How to restrict the filtering issue in WinForms GridControl?

3 mins read

Restrict the filtering issue

The Filter bar can be added to the virtual grid of the WinForms GridControl when you set BrowseOnly or ReadOnly to the grid, you cannot filter using the filter bar because BrowseOnly is also applied to the filter bar. To resolve this, use the following method.

Solution

Instead of setting ReadOnly or BrowseOnly, you can cancel the cell editing for the all the cells except the Filter bar row by setting e.cancel as True in the CurrentCellStartEditing event. The following code example is for cancelling the row.

C#

//Hooking Currentcell startEditing event.
this.gridControl1.CurrentCellStartEditing += new CancelEventHandler(gridControl1_CurrentCellStartEditing);
void gridControl1_CurrentCellStartEditing(object sender, CancelEventArgs e)
{
    GridCurrentCell cc = this.gridControl1.CurrentCell;
    if (cc != null && cc.RowIndex != 1 && cc.ColIndex > 0)
    {
        //Cancel editing process except filterbar and rowheader before it starts.
        e.Cancel = true;
    }
}

VB

'Hooking Currentcell startEditing event.
Private Me.gridControl1.CurrentCellStartEditing += New CancelEventHandler(AddressOf gridControl1_CurrentCellStartEditing)
Private Sub gridControl1_CurrentCellStartEditing(ByVal sender As Object, ByVal e As CancelEventArgs)
 Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell
 If cc IsNot Nothing AndAlso cc.RowIndex <> 1 AndAlso cc.ColIndex > 0 Then
  'cancel editing process except filterbar and rowheader before it starts.
  e.Cancel = True
 End If
End Sub
