Well what debugging have you done? What's the value of `e.row.index`? (That doesn't look like it should even compile, by the way...) — Jon Skeet, Feb 19 '13 at 14:45

Check that e.Row.Index is greater than 0, there are reasons that it could be -1 which is an invalid index in the BindingSource.

public void UserDeletingEvent(object sender, EventArg e)
{
    if (e.Row.Index >= 0)
    {
        BindingSource.RemoveAt(e.Row.Index);
    }
}

I found the index did not represent an actual row when the user clicked on the heading or the background area. You have to test that it is a valid index.
