[Resolved]Displaying item on datagrid?

I've been trying to add an item to my datagrid but when I add one it just displays a blank row. When I use msgbox to see the item text it shows the value I want to display. So my question is, why doesn't the datagrid display "test"?

Here's my vb:

Code:

---

Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
        'add columns to datagrid
        Dim linkColumn As New DataGridTextColumn : Dim titleColumn As New DataGridTextColumn
        linkColumn.Header = "Links:" : titleColumn.Header = "Titles:"
        linkColumn.Width = DataGrid1.Width / 2 : titleColumn.Width = DataGrid1.Width / 2
        linkColumn.Binding = New System.Windows.Data.Binding("Links") : titleColumn.Binding = New System.Windows.Data.Binding("Titles")
        DataGrid1.Columns.Add(linkColumn) : DataGrid1.Columns.Add(titleColumn)

        mainTimer.Interval = 5000 : mainTimer.Enabled = True

        DataGrid1.Items.Add("test")
        MsgBox(DataGrid1.Items.Item(0).ToString) 'although the datagrid won't show it, this displays "test". why?
End Sub

---

Not sure if it's needed to help me but here's my XAML:

Code:

---

<DataGrid AutoGenerateColumns="False" Height="289" HorizontalAlignment="Left" Margin="10,10,0,0" Name="DataGrid1" VerticalAlignment="Top" Width="481" Grid.ColumnSpan="2" ItemsSource="{Binding}" />

Hi,

Here's a code sample:

Code:

---

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            DataGridTextColumn c1 = new DataGridTextColumn();
            c1.Header = "Test";
            c1.Binding = new Binding("test");
            c1.Width = 473;
            dataGrid.Columns.Add(c1);
            dataGrid.Items.Add(new Names() {test="just testing"});
   
        }

---

And here's a simple class declaration

Code:

---

class Names
    {
        public string test { get; set; }
    }

---

Make sure the column is bound to the property of Names class.

Ok so I tried something like that:

Code:

---

DataGrid1.Items.Add(New DataItems() With {.Link = "http://test.com", .Title = "test"})

---

and the class for dataitems is:

Code:

---

Public Class DataItems
    Private _link As String
    Public Property Link() As String
        Get
            Return _link
        End Get
        Set(l As String)
            _link = l
        End Set
    End Property

    Private _title As Integer
    Public Property Title() As Integer
        Get
            Return _title
        End Get
        Set(t As Integer)
            _title = t
        End Set
    End Property
End Class

---

But it didn't display anything on runtime.

Hi,

Your property title is wrong, you should change the property type to String. It will create a type cast error.

I've created a VB version out from this.

Here are some of the snippets:

Code:

---

Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded

        Dim linkColumn As New DataGridTextColumn : Dim titleColumn As New DataGridTextColumn
        linkColumn.Header = "Links:" : titleColumn.Header = "Titles:"
        linkColumn.Width = dataGrid.Width / 2 : titleColumn.Width = dataGrid.Width / 2
        linkColumn.Binding = New System.Windows.Data.Binding("Link") : titleColumn.Binding = New System.Windows.Data.Binding("Title")
        dataGrid.Columns.Add(linkColumn) : dataGrid.Columns.Add(titleColumn)
        dataGrid.Items.Add(New DataItems() With {.Link = "http://testingme.com", .Title = "mytesting"})
    End Sub

---

Code:

---

Public Class DataItems
    Private _link As String
    Public Property Link() As String
        Get
            Return _link
        End Get
        Set(ByVal l As String)
            _link = l
        End Set
    End Property

    Private _title As String
    Public Property Title() As String
        Get
            Return _title
        End Get
        Set(ByVal t As String)
            _title = t
        End Set
    End Property
End Class

---

For the xaml code:

Code:

---

<Grid>
        <DataGrid AutoGenerateColumns="False" Height="289" HorizontalAlignment="Left" Margin="10,10,0,0" Name="dataGrid"
                  VerticalAlignment="Top" Width="481" Grid.ColumnSpan="2" ItemsSource="{Binding }">
        </DataGrid>
    </Grid>

---

This works fine on my end..

Cheers!
