Bound DataGridView not updating to display information + sorting issues

Question

I have a bound DataGridView1 and several bound TextBoxes and DateTimePickers.

Everything is working well, except when I try to accomplish these two things in conjunction

Answer 1

DGV shows edited value after cell validation and this seems to be an issue around DGV. In order to do that (considered as workaround) you can simulate/force by yourself your grid validation (calling the method below) after you have setted the value on your cell:

Private Sub SimulateDGVValidation()

    Try

        Dim currentCell As DataGridViewCell = Me.DataGridView1.CurrentCell

        If (currentCell) IsNot Nothing Then
            Dim c As Integer = IIf(currentCell.ColumnIndex > 1, currentCell.ColumnIndex - 1, 1)
            Me.DataGridView1.CurrentCell = Me.DataGridView1(c, currentCell.RowIndex)
        Else
            Me.DataGridView1.CurrentCell = Me.DataGridView1(0, 0)
        End If


        Application.DoEvents()

        'Return in the initial cell 
        If (currentCell) IsNot Nothing Then
            Me.DataGridView1.CurrentCell = currentCell
        End If


    Catch ex As Exception
        Console.WriteLine(ex.ToString)
    End Try

End Sub
