Sony Kdl 32v4500 Update Itunes here. May be this question is not much important for you but I am facing problem in this. I have a DataGridView in which I add rows. If Me.Dgv.Rows.Count = 0 Then SlNo = 1 Else SlNo = Me.Dgv.Rows.Count + 1 End If Me.Dgv.Rows.Add(SlNo, ItemId, ItemName, Qty, ItemRate, Amt) and the rows display like.

DataGridView.RowPrePaint event will be raised every time when datagridview must be repainting. This will happened for example when you drag over datagridview another form or MessageBox or when you minimize/hide form and reopen it again. In your case you need update Serial No only after count of the rows was changed. 'Method looping all rows and update value of `Sl No` column based on index of row Private Sub Dgv_RowCountChanged() For Each dgvr As DataGridViewRow in Me.Dgv.Rows dgvr.Cells(0).Value = dgvr.Index + 1 Next End Sub Method Dgv_RowCountChanged will be executed in the event handlers of RowsAdded and RowsRemoved Private Sub Dgv_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e) Handles Dgv.RowsAdded Me.DgvCountChanged() End Sub Private Sub Dgv_RowsRemoved(object sender, DataGridViewRowsRemovedEventArgs e) Handles Dgv.RowsRemoved Me.DgvCountChanged() End Sub.
