Can't access Cell data in DataGridView VB.Net












0















I've got a project in Visual Studio 2017, using VB.NET that populates a DataGridView using a DataTable. The data appears fine in the grid, but when I try to access the cell value in the SelectionChanged event, I always get Nothing. Here's the event:



    Private Sub grdBooks_SelectionChanged(sender As Object, e As EventArgs) Handles grdBooks.SelectionChanged
If Not grdBooks.CurrentRow Is Nothing Then
If grdBooks.CurrentRow.Index > -1 Then
Dim X As String = grdBooks.Rows(0).Cells(0).Value
Dim Y = grdBooks(0, 0).Value
UpdateEditPanel(False)
End If
End If
End Sub


So both X and Y should give me the same value from the grid at position 0,0 but they don't. I've used this before in other projects. Does anybody have any ideas?



Thanks, Colin

  • Did you by chance add a DataGridviewColumn with (Visible=False) to the DataGridview prior to binding the DataTable? Possibly via the designer. Try adding DataGridView1.Columns.Clear() before setting the DataSource.

    You have a confusing post. You say the cell is always nothing, but then you say x and y should be the same value but aren't. Which issue is it? The code you posted does not support either issue.

  • The code sample you provided works for me. I see the value in cell 0/0 when I select different items in the grid.

I am a bit confused by this post aswell but I hope this helps you resolve the problem. Possible solution #1



Dim X As String = DataGridView1.SelectedRows(0).Cells(0).Value.ToString 


or



Dim X As String = DataGridView1.SelectedRows(0).Cells(0).Value.ToString() 


If you are able to provide more code, I'm sure we can resolve this Issue. Cheers.

    If you just want to click the cell from the Grid, try this:



    Private Sub grdBooks_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles grdBooks.CellContentClick

    Dim selectedRow As DataGridViewRow

    selectedRow = grdBooks.Rows(e.RowIndex)

    Dim x as string = selectedRow.Cells(0).Value.ToString()


    End Sub
