Hi,
I use CellPainting to show column total in datagridview...
When I load my form totals are calculated OK...
After I change content of cell in datagridview I expect totals to be changed but unfortunatelly it does not happens....It's recalculated when I change for eg width  of column where cell value is changed
How can I call cellPainting to recalculate totals after cell value is changed....

Please help

Thanks...

Code below...
Public Sub DataGridView1_CellPainting(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellPaintingEventArgs) Handles DataGridView1.CellPainting

        Dim sum As Decimal = 0.0
        If (e.RowIndex = DataGridView1.NewRowIndex And e.ColumnIndex > 1) Then
            For i As Integer = 0 To DataGridView1.NewRowIndex - 1
                If (DataGridView1.Rows(i).Cells(e.ColumnIndex).Value.ToString().Trim() <> "") Then
                    sum += Convert.ToDecimal(DataGridView1.Rows(i).Cells(e.ColumnIndex).Value)
                End If
            Next i

            e.PaintBackground(e.CellBounds, False)
            e.Graphics.DrawString(sum.ToString(), DataGridView1.Font,
 Brushes.Black, e.CellBounds.Left + 2, e.CellBounds.Top + 2)
            e.Handled = True
        End If
    End Sub

Try using the CellEndEdit event of the datagridview instead

Hi,
thank you for your reply...
Errors are as follows:
'PaintBackground' is not member of System.Windows.Forms.DataGridViewCellEventArgs
'Handled' is not member of System.Windows.Forms.DataGridViewCellEventArgs
'Graphics' is not member of System.Windows.Forms.DataGridViewCellEventArgs
......

Do you have any other idea what should I do?
Thanks

Something like this do what you need?

Private Sub dataGridView1_CellEndEdit(ByVal sender As Object, _
    ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
    Handles dataGridView1.CellEndEdit

Dim sum As Decimal = 0.0
        If (e.RowIndex = DataGridView1.NewRowIndex And e.ColumnIndex > 1) Then
            For i As Integer = 0 To DataGridView1.NewRowIndex - 1
                If (DataGridView1.Rows(i).Cells(e.ColumnIndex).Value.ToString().Trim() <> "") Then
                    sum += Convert.ToDecimal(DataGridView1.Rows(i).Cells(e.ColumnIndex).Value)
                End If
            Next i
           
        End If
        DataGridView1.Rows(NewRowIndex + 2).Cells(e.ColumnIndex + 2).Value = sum
End Sub
