Hi,

I am trying to add ability to delete multiple rows from a DataGridView
in my application. When user selects multiple rows and presses delete
button, I want to show a message asking to user to confirm delete. I am
using UserDeletingRow event.

My problem is that if 5 rows are, 5 different events are triggered. If
I handle UserDeletingRow, I will have to ask for user's confirmation 5
times. Is there any way to avoid this and ask for confirmation only
once.

Thanks in advance for your help,

Manju

The problem with so many uses of DataGridView is that people forget that it
was intended to be a UI component displaying data that is not held in the
grid.

If your data is held in either a list or table, then the answer is to remove
the items from the list or table, then the grid will update to reflect the
changes in the underlying data.

You may use KeyPress event instead of UserDeletingRow. Detect if DEL was
pressed and if there are any rows selected. If so, delete all these rows
with foreach statement.
