Hello,

Can you please provide some more details on exactly what you are trying to achieve here?

There are a lot of different ways you can handle the row deletion,
First and foremost the most easiest way is to handle the UserDeleting/UserDeletedRow event and update db there.
Another option would be to handle the RowsChanging event and check for the Remove action, like so:

void radGridView1_RowsChanging(object sender, GridViewCollectionChangingEventArgs e)
{
    if (e.Action == NotifyCollectionChangedAction.Remove)
    {
        //update db
    }
}

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,

Hello again,

Please take a look at the following sample:

Private Sub button_Click(sender As Object, e As EventArgs)
    Dim selectedRows = radGridView1.SelectedRows.ToArray()
    For i As Integer = selectedRows.Length - 1 To 0 Step -1
        Dim row = selectedRows(i)
            ' do something else maybe here
        radGridView1.Rows.Remove(row)
    Next
End Sub

Hope this helps, if you have any other questions or comments, please let me know,
