Paste Special option in right click menustrip

Hello Rajasekaran,
We provide the PasteSpecialCommand command, which allows you to invoke the Paste Special dialog. To open the dialog programmatically, invoke this command as follows:

C#
PasteSpecialCommand cmd = new PasteSpecialCommand(spreadsheetControl1);  
cmd.Execute();  

If you want to add the "Paste Special" item to the context menu, handle the SpreadsheetControl.PopupMenuShowing event as shown below:

C#
private void SpreadsheetControl1_PopupMenuShowing(object sender, DevExpress.XtraSpreadsheet.PopupMenuShowingEventArgs e)  
{  
    PasteSpecialCommand cmd = new PasteSpecialCommand(spreadsheetControl1);  
    SpreadsheetMenuItemCommandWinAdapter menuItemCommandAdapter = new SpreadsheetMenuItemCommandWinAdapter(cmd);  
    SpreadsheetMenuItem menuItem = (SpreadsheetMenuItem)menuItemCommandAdapter.CreateMenuItem(DevExpress.Utils.Menu.DXMenuItemPriority.Normal);  
    menuItem.BeginGroup = true;  
    e.Menu.Items.Add(menuItem);  
}  

You may also use the CTRL+ALT+V shortcut to invoke the Paste Special dialog.
I hope that you find this information helpful.
