How to prevent the grid cell from allowing paste in WinForms GridControl?
Handle the PasteCellText event
You have to
handle the PasteCellText event of the GridControl and
cancel the event that prevents the cells from allowing paste. This event is not
triggered when the current cell is in Edit mode.
//In Form_Load
this.gridControl1[1, 2].Text = "HI";
this.gridControl1.ActivateCurrentCellBehavior = GridCellActivateAction.DblClickOnCell;
//using the PasteCellText Event
void gridControl1_PasteCellText(object sender, Syncfusion.Windows.Forms.Grid.GridPasteCellTextEventArgs e)
{
//Row 3 as prevent from paste
if (e.RowIndex == 3)
e.Cancel = true;
}' In Form_Load
Me.gridControl1(2, 2).Text = "HI"
Me.gridControl1.ActivateCurrentCellBehavior = GridCellActivateAction.DblClickOnCell
Private Sub gridControl1_PasteCellText(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.GridPasteCellTextEventArgs)
' Row 3 as prevent from paste
If e.RowIndex = 3 Then
e.Cancel = True
End If
End SubWhen you want to avoid pasting into a cell that is in Edit mode, you can make use of the CurrentCellControlKeyMessage event. In the following code, the paste operation is specified by the shortcut key Ctrl+V.
void gridControl1_CurrentCellControlKeyMessage(object sender, GridCurrentCellControlKeyMessageEventArgs e)
{
Keys keyCode = (Keys)((int)e.Msg.WParam) & Keys.KeyCode;
//Condition for Ctr+V keys
if ((Control.ModifierKeys & Keys.Control) != 0 && keyCode == Keys.V )
{
GridCurrentCell cc = this.gridControl1.CurrentCell;
//set the row 3 as prevent from paste
if(cc.RowIndex == 3)
e.Handled = true;
e.Result = true;
}
}Private Sub gridControl1_CurrentCellControlKeyMessage(ByVal sender As Object, ByVal e As GridCurrentCellControlKeyMessageEventArgs)
Dim keyCode As Keys = CType(CInt(Fix(e.Msg.WParam)), Keys) And Keys.KeyCode
If (Control.ModifierKeys And Keys.Control) <> 0 AndAlso keyCode = Keys.V Then
' set the row 3 as prevent from allow paste
Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell
If cc.RowIndex = 3 Then
e.Handled = True
End If
e.Result = True
End If
