UserDeletingRow sender

[Nadia Sangiovanni]

Hi Support,

Is there a way to know if the UserDeletingRow have been called from the delete button or from cell context menu delete or from row header context menu?

Regards,

Hi Nadia,

Thank you for writing.

Currently, there is no direct way to determine what triggered the deletion from within the event. This thought is a good idea and I have logged it into our Public Issue Tracking System - PITS. You can track its status and add your vote/comment to it at the following link - PITS Feature. A possible work around is to use flags which are raised when the context menu is opened. Here is an example:

bool cellContextMenu = false;
bool rowHeaderContextMenu = false;

private void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
  if (e.ContextMenuProvider is GridDataCellElement)
  {
    this.cellContextMenu = true;
  }
  else if (e.ContextMenuProvider is GridRowHeaderCellElement)
  {
    this.rowHeaderContextMenu = true;
  }
}

private void radGridView1_UserDeletingRow(object sender, GridViewRowCancelEventArgs e)
{
  if (this.cellContextMenu)
  {
    this.cellContextMenu = false;
    MessageBox.Show("Cell context menu");
  }
  else if (this.rowHeaderContextMenu)
  {
    this.rowHeaderContextMenu = false;
    MessageBox.Show("Row header context menu");
  }
  else
  {
    MessageBox.Show("Pressed delete key");
  }
}

I have updated your Telerik points for the suggestion.

I hope this will be useful. Should you have further questions, I would be glad to help.
