Using a DatagridView in .net 2.0

How would you go about implementing an "undo" event?

So if the user selects a row in the datagridview, then hits the delete key,
I handle the deletion by using the "datagridviews.rows.removeat" function.

This removes the row from the datagridview, but the row should still be
available because I have not yet committed the change to the database.

Is there a simple property or method I can use to make the row visible again?

thanks

I don't know if this is the correct way to do it...but I managed to get what
I wanted by doing the following..

For the datasource (in my case a datatable), I called the "RejectChanges"
method and then with the bindingsource, i called "resetbindings"

this reset the status of the deleted row, then reset the datagridview so
that the value was now showing again.

Hi Ausclad,

Don't know if it's what your looking for (Or if it's the best way...):
Store the complete row(s) you want to delete within a private
DataGridViewRowCollection before deleting them. When you click on your
'Undo' - Button or whatever, you can raise your event which should then
pump the deleted values into the grid.

Does that help?
