    Re: opening xml file to datagrid view for editing

    How did you save that xml file in the first place?
    You need to be more especific then that.

    Re: opening xml file to datagrid view for editing

    this is how i saved it
    Code:
    If MainForm.SaveFileDialog.ShowDialog = DialogResult.OK Then
                Dim writer As New XmlTextWriter(MainForm.SaveFileDialog.FileName, System.Text.Encoding.UTF8)
                writer.WriteStartDocument(True)
                writer.Formatting = Formatting.Indented
                writer.Indentation = 3
                writer.WriteStartElement("Table")
                For r As Integer = 0 To ActiveSheet.dgvScoreSheetTable.RowCount - 2
                    Dim c0 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(0).Value)
                    Dim c1 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(1).Value)
                    Dim c2 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(2).Value)
                    Dim c3 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(3).Value)
                    Dim c4 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(4).Value)
                    Dim c5 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(5).Value)
                    Dim c6 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(6).Value)
                    Dim c7 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(7).Value)
                    Dim c8 As String = CStr(ActiveSheet.dgvScoreSheetTable.Rows(r).Cells(8).Value)
                    WriteData(c0, c1, c2, c3, c4, c5, c6, c7, c8, writer)
                Next
                writer.WriteEndElement()
                writer.WriteEndDocument()
                writer.Close()
            End If
    the file opens quite alright but when i want to edit it, it generates an error

    Re: opening xml file to datagrid view for editing

    Diferent aprouche to xml saving and reading, using a datatable as datasource of the datagridview control you have:

    main form code:

    Code:
    Public Class mainFrm
    
        Private SHEETCOUNT As Integer = 1
    
        Private Sub mainFrm_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    
        End Sub
    
        Private Sub NewToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles NewToolStripMenuItem.Click
    
            CREATE_NEW_WORKSHEET()
    
        End Sub
    
        Private Sub CREATE_NEW_WORKSHEET()
    
            Dim NWRKSHEET As New NWSHEET
            With NWRKSHEET
                .Name = String.Format("NEWWRK{0}", SHEETCOUNT)
                .Text = String.Format("New worksheet {0}", SHEETCOUNT)
                .MdiParent = Me
                .Show()
            End With
            SHEETCOUNT += 1
    
        End Sub
    
        Private Sub SaveAsToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles SaveAsToolStripMenuItem.Click
    
            Dim F = CType(ActiveMdiChild, NWSHEET)
            F.SaveAsXmlFile
    
        End Sub
    
        Private Sub OpenToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles OpenToolStripMenuItem.Click

                        .MdiParent = Me
                        .Show()
                    End With
                    SHEETCOUNT += 1
                End If
            End Using
    
        End Sub

                'Use Expression to calculate the total score
                .Expression = "C2 + C3"
            End With
            TB.Columns.Add(CL4)

        Friend Sub SaveXmlFile()
    
            TB.WriteXml(Tag.ToString, True)
    
        End Sub
    
        Friend Sub SaveAsXmlFile()
    
            Using SVDLG As New SaveFileDialog
                SVDLG.Filter = "Xml file|*.xml"
                SVDLG.Title = "Save an Xml File"
                SVDLG.ShowDialog()
                If SVDLG.FileName <> "" Then
    
                    TB.WriteXml(SVDLG.FileName, True)
                    Tag = SVDLG.FileName
                    ISNEW = False
    
                End If
    
            End Using
    
    
        End Sub
    
    End Class
    Note that main form is a mdicontainer and only has a menustrip control and the new sheet form only has a datagrid called DGV1.
    Thats raw code, it can be improved in many points, its just to give you a ideia of how easy is to load xml to a table and save it back to a xml file.

    Re: opening xml file to datagrid view for editing

    what if i want to use this kind of expression on a column how will i place it
    Code:
    Dim rows = dgvScoreSheetTable.Rows.
            Cast(Of DataGridViewRow)().OrderByDescending(Function(row) CInt(row.Cells(6).Value)).ToArray()
            For a = 0 To rows.GetUpperBound(0)
                rows(a).Cells(7).Value = a + 1

    I agree. You have shown a solution, not a statement of the problem.

    If you want / have to use XML then show the XML file (or part of it) also.

    Re: opening xml file to datagrid view for editing

    People are scratching their heads because this is sort of a weirder question than you think.

    DataGridView was made for displaying database data. It has a concept of "tables". Tables are made of "Rows", and each row has "Columns" that contain values. The logic of what "a value" means is separated from what .NET considers as "variable types". It has concepts of "constraints" and "relations" that aren't modeled well by the object-oriented approach of .NET languages unless you do work to implement those features yourself.

    XML is a text format for representing object models. But it's a very bad format for representing object models, because for any given object there's more than one "obvious" way to represent the object. For example, consider this simple "Customer":
    Code:
    Public Class Customer
        Public Property Name As String
    End Class
    If you pick 100 developers and ask them to describe a customer with XML, you are going to get a 50/50 split between:
    Code:
    <Customer Name="Dale Cooper" />
    Code:
    <Customer>
        <Name>Dale Cooper</Name>
    </Customer>
    99% of developers in the world have standardized on JSON instead, because there's only one "sane" way to describe this Customer in JSON:
    Code:
    { "Name" : "Dale Cooper" }
    But that's a different story, we're using XML.

    "Objects" and "tables" have a lot in common. We can argue that "columns" are like "properties". So it ought to be true that we can convert from XML to objects, objects to tables, thus via transitive logic we think "objects", "tables", and "XML" should all be compatible.

    So DataTable and DataSet have some methods that will read XML and create tables/columns/rows for you. But because XML is ambiguous, there are a lot of limitations. If you want it to work best, your XML needs to provide a full schema so the code can generate the correct columns for each table. If you don't provide a schema, the "easy" code doesn't have a clue whether this XML represents an Integer, a String, or some other type entirely:
    Code:
    <Value>25</Value>
    So if you don't have a schema, the best you'll get out of the "easy" methods is "everything in your XML is considered a String, it's up to YOU to do conversions. Fun.

    (To be fair, JSON isn't much better. Oversimplifying, it recognizes String, Double, and Boolean as variable types and nothing else. So if you want Integer and Byte to be distinct types, you have work to do with JSON.)

    When you don't have a schema, it is YOUR job to do to the work to tell VB what type each XML element corresponds to. That generally means you can't use a simple method like ReadXml(). You have to follow this process:
    1. Define the DataTables you need, making sure to set up DataColumns with the right types.
    2. Open the XML document with your favorite XML parser (MS has provided three so far, and will add more when they decide people aren't confused anymore.)
    3. Parse each XML element into the appropriate DataRow of the appropriate DataTable in your DataSet.
    4. Profit!

    That means you either have to 1) follow the rules that ReadXML() expects, which means writing a schema for your XML or 2) do all the work yourself.

    So the question you're asking is overly broad. There's no one way to "get an XML document into a DataGridView". You have to start with, "This is my XML", then answer questions like, "Can you change the format?" or "Can you write a schema?".
    Nothing I post is production-ready. It is provided as-is, use it at your own risk.

    Re: opening xml file to datagrid view for editing

    ok defining my question more vividly read this
    Code:
    'This code is in the parent form
    Public Class MainForm
     
    Private Sub NewToolStripMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripMenuItem1.Click

    You originally asked about opening an XML file to edit it. You suggested using a DGV for that purpose. I pointed out that that might not be the best approach and asked that you describe the problem without a 'solution' and to show the XML file or portion.

    Good luck.

    Re: opening xml file to datagrid view for editing

    I think it has been suggested that you process the XML manually within your OpenScoreSheet() sub instead of trying to directly read in into a data table. If it was me, I would do something like this, to get each 'value' and then populate the DGV for each row, or add to the data table.

    Code:
    Dim document As XmlReader = New XmlTextReader('your file name')
    While (document.Read())
           Dim type As XmlNodeType = document.NodeType
           If (type = XmlNodeType.Element) Then 
                 Select Case document.Name.ToUpper
                            Case "ADMIN_NAME"
                                m_admin = document.ReadInnerXml  ' You can convert each string value to the correct type as required, int, decimal etc.
                            Case "C.A.1"
                                m_CA1element = document.ReadInnerXml)
                            ' Etc. Etc.
                 End Select 
           End If
    End While

    Re: opening xml file to datagrid view for editing

    Here is an example. Create a form and add a button and DataGridView. Use the default names. Use this code
    Code:
    Public Class Form1
    
        Private xe As XElement
        Private myRecs As Records
    
        Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing
            Stop 'examine xe and myRecs
            ' myRecs.Save("PATH HERE")
        End Sub
    
        Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
            Me.Button1.Visible = False
            'test data
            xe = <Table>
                     <Record>
                         <ADMIN_NUMBER>5565</ADMIN_NUMBER>
                         <NAME>yyghjj</NAME>
                         <C.A.1>65</C.A.1>

    Click button 1. Make changes to the DGV and then close the app. There is a breakpoint in the close so you can see what happened. I only added a few of the properties to give you an idea of what to do

    Re: opening xml file to datagrid view for editing

    Application events:

    Code:
    Imports Microsoft.VisualBasic.ApplicationServices
    
    Namespace My
        ' The following events are available for MyApplication:
        ' Startup: Raised when the application starts, before the startup form is created.
        ' Shutdown: Raised after all application forms are closed.  This event is not raised if the application terminates abnormally.
        ' UnhandledException: Raised if the application encounters an unhandled exception.
        ' StartupNextInstance: Raised when launching a single-instance application and the application is already active. 
        ' NetworkAvailabilityChanged: Raised when the network connection is connected or disconnected.
        Partial Friend Class MyApplication

    Re: opening xml file to datagrid view for editing

    You can dowload it from here:

    Link removed...

    In the project i added also another function to save columns width under the event ColumnWidthChanged



    Code:
      Private Sub TABLEDGV_ColumnWidthChanged(sender As Object, e As DataGridViewColumnEventArgs) Handles TABLEDGV.ColumnWidthChanged
    
            Try
    
                Dim STR1 As String = CType(e.Column.Width, String)
                Dim STR2 As String = CType(DirectCast(BSOURSE.DataSource, DataSet).
                    Tables(BSOURSE.DataMember).Columns(e.Column.Index).ExtendedProperties("Width"), String)
    
                If CBool(String.Compare(STR1, STR2)) Then
    
                    If Not DirectCast(MainFrm.ActiveMdiChild.Tag,
                    WORKBOOK_CLS).CHANGE_PROPERTIES(TABLEDGV.Columns(e.Column.Index).DataPropertyName,
                                                    "Width", TABLEDGV.Columns(e.Column.Index).Width.ToString) Then
    
                        MessageBox.Show("Wasn't possible to perform the changes...", "Table to xml...", MessageBoxButtons.OK, MessageBoxIcon.Error)
    
                    End If
    
                End If
    
            Catch ex As Exception
                MessageBox.Show(ex.Data.ToString & vbNewLine & ex.StackTrace, "Table to xml...", MessageBoxButtons.OK, MessageBoxIcon.Error)
            End Try

    Re: opening xml file to datagrid view for editing

    By the way, how did you save this file?
    You didnt use DataSetWriteXml("FileName", XmlWriteMode.WriteSchema)?

    Re: opening xml file to datagrid view for editing

    Ok, like i said the 1 is the extended properties thats this project requires, the second is thats in fact 3 tables, or 1 table and 2 child tables.
    If i use DataTable.ReadXml(OFDLG.FileName) it gives me a error "DataTable does not support schema inference "

    this is the code i used:

    Code:
    Friend Sub OPEN_TABLE()
    
            Try
                Using TB As New DataTable()
    
                    Using OFDLG As New OpenFileDialog
    
                        OFDLG.Filter = "mXml file|*.mXml|Xml files |*.xml"
                        OFDLG.Multiselect = False
    
                        If OFDLG.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
    
                            TB.ReadXml(OFDLG.FileName)
                            WBDATASET.Tables.Add(TB)
    
                        End If
    
                    End Using
    
                End Using
    
            Catch ex As Exception
                MessageBox.Show(ex.Message & vbNewLine & ex.StackTrace, "Simple sable to xml...", MessageBoxButtons.OK, MessageBoxIcon.Error)
            End Try
    
        End Sub
    If i modify the code i had to open a xml file originaly to this:

    Code:
     ''' <summary>
        ''' Opens a saved workbook or creates a new one from a template
        ''' </summary>
        ''' <param name="File_Name">File full name</param>
        Friend Sub New(FILE_NAME As String)
    
            Try
    
                WBDATASET = New DataSet
                WBDATASET.ReadXml(FILE_NAME)
                Dim FL As New IO.FileInfo(FILE_NAME)
    
                Dim FRM As New WB_FORM
                WBPARENT = FRM
    
                With FRM
    
                    .Text = FL.Name
                    .Name = WBDATASET.DataSetName
                    .MdiParent = MainFrm
    
                    For Each T As DataTable In WBDATASET.Tables
    
                        Dim UC As New TABLEVIEWER_UC(WBDATASET, T.TableName)
                        'T.ExtendedProperties.Item("Caption").ToString
    
                        Dim TBPAGE As New TabPage(T.TableName) With {
                                                    .Tag = T.TableName}
                        TBPAGE.Controls.Add(UC)
                        .TBCONTAINER.TabPages.Add(TBPAGE)
    
                    Next
    
                    .Tag = Me
                    .Show()
                    WBFULLNAME = FILE_NAME
                    IsNEW = False
    
                    If WBDATASET.Tables.Count > 0 Then
    
                        DirectCast(MainFrm.ActiveMdiChild, WB_FORM).TBCONTAINER.SelectedIndex = 0
                        ACTIVE_TABLE = DirectCast(MainFrm.ActiveMdiChild, WB_FORM).TBCONTAINER.SelectedTab.Tag.ToString
    
                    End If
    
                End With
    
            Catch ex As Exception
                MessageBox.Show(ex.Message & vbNewLine & ex.StackTrace, "Simple sable to xml...", MessageBoxButtons.OK, MessageBoxIcon.Error)
            End Try
    
        End Sub
    also had to comment the folwing code under TABLEVIEWER_UC

    Code:
    'Dim ALGN = DST.Tables(Table_Name).Columns.Item(I).ExtendedProperties("Alignment")
                'If ALGN.ToString.Length > 0 Then
    
                'If ColumnAlign.Values.Contains(CInt(ALGN)) Then
    
                'TABLEDGV.Columns(I).DefaultCellStyle.Alignment = CType(ALGN, DataGridViewContentAlignment)
    
                ' End If
    
                'End If
    It creates me 3 tables.
    So i wonder if this is not a dataset with a Parent table and 2 childtables with relationship's?
    In that case to open it in my project you will need to do some adjustmens in one of the projects.
    This was made save and read from a dataset.

    Re: opening xml file to datagrid view for editing

    A single table with out schema would look like this

    Code:
    <?xml version="1.0" standalone="yes"?>
    <DataSetName>
      <TableName>
        <EmpId>1</EmpId>
        <Name>Sam</Name>
        <Sex>Male</Sex>
        <Home phone>423-555-0124</Home phone>
        <Work phone>424-555-0545</Work phone>
        <Address>7A Cox Street</Address>
        <City>Acampo</City>
        <State>CA</State>
        <Zip>95220</Zip>
        <Country>USA</Country>
      </TableName>
    </DataSetName>
    With the schema and extended properties:

    Code:
    <?xml version="1.0" standalone="yes"?>
    <Workbook1>
      <xs:schema id="Workbook1" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop">

    Re: opening xml file to datagrid view for editing

    You welcome, i think thats a better way to deal with tables and store them in xml files then use a unbound datagridview.
    Improve the code to your needs, correct any errors that i may have not paid atention to.

    Use the project in the last link, code has been modified since i post it the first time.
