Excel and Datagridview

Hi All

The end of my current project is in site.

However, one thing still to sort.

I have a datagridview which I would like to be able to export the information to an Excel spreadsheet, and be able to reload the information later on from a spceified worksheet.

I've found a few "solutions" online, but none of them seem to work and so I need some major help.

My level of programming is very, very basic and so please forgive any ignorance which may happen throughout this!

Also, I'd like to avoid using Databases with Access etc because I am aware that some of the machines I'll be deploying the programme on do not have Access installed and would not want to have to install it either.

Thanks for your help

What do you mean "reload the information later on from a specified worksheet?

basically, save the information to that spreadsheet, and should the programme with the DGV in it be closed for whatever reason, be able to select the worksheet to reload to continue working on it .. :)

open it from excel??
Here is some code that will create an excel sheet for you, may have to tweak it a bit but it should get you there

Code:

---

Dim misValue As Object = System.Reflection.Missing.Value
        Dim i As Integer
        Dim j As Integer

        xlApp = New Excel.ApplicationClass
        xlWorkBook = xlApp.Workbooks.Add(misValue)
        xlWorkSheet = CType(xlWorkBook.Sheets("Sheet1"), Excel.Worksheet)

        For Each col As DataGridViewColumn In DataGridView1.Columns

            xlWorkSheet.Cells.Columns.CurrentRegion.Columns(col.Index + 1) = col.HeaderText.ToString
        Next
        For i = 0 To DataGridView1.RowCount - 2
            For j = 0 To DataGridView1.ColumnCount - 1
                If worker.CancellationPending Then
                    e.Cancel = True
                    Exit For
                End If
                xlWorkSheet.Cells(i + 2, j + 1) = _
                    DataGridView1(j, i).Value.ToString()

                  Next
        Next

            xlWorkBook.Close()
            xlApp.Quit()
            releaseObject(xlApp)
            releaseObject(xlWorkBook)
            releaseObject(xlWorkSheet)

Thanks for this! Getting some blue underlines saying "declaration expected" ...sorry for my lack of knowledge :S

You might consider not dealing with Excel at all. Excel can open XML files easily, Excel can also write XML files easily, and that will be much easier for exporting and importing.

Would help if you gave more information

but you probably need these place under you Public class form

Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet

just go to this thread & find the signature "Export DGV to word ~ excel " in .pouls signature.

this is a good note
