Delete datagridview row using right click context menu does not behave like the delete key

Question

I have a datagridview with editing enabled. If I click the row header and press the delete key, the row is removed no questions asked. I don't recall doing any coding to make this happen but I couldn't do copy and paste using keys so I created a context
menu with copy, paste, & delete.  The delete option calls
dgvVX130.Rows.RemoveAt(dgvVX130.SelectedRows[0].Index);
The row is removed but the problem is this fires other events like RowValidating which fails.  I presume because the row is no longer there.
The delete keypress is definitely a lot cleaner so my question is 3fold. 
1) Why doesn't Rows.RemoveAt behave like the delete key? 
2) Is it possible to issue a delete keypress to do the same thing?
3)  Is it possible to suppress the RowValidating event or other events when Rows.RemoveAt is fired?

Answer 1

Interesting.  My delete key does not fire the row validating event.  When I use the delete key I click on the row header which does fire the row validating event and then I press the delete key.  Row is deleted and no event fires.  Works
just the way I want it to.  I wish my context menu delete worked that way.  I wouldn't know what chunk of code I can provide to show the Row Validating NOT firing when delete key is pressed but here is the context menu code that does fire Row Validating.

ToolStripItem item = e.ClickedItem;

try
// Add the selection to the clipboard.
Clipboard.SetDataObject(
dgvVX130.GetClipboardContent());
// Replace the text box contents with the clipboard text.
catch (System.Runtime.InteropServices.ExternalException)
MessageBox.Show("The Clipboard could not be accessed. Please try again.");
