VB 2008  - How to avoid (and commit) a deletion; DataGridView

My concern is with activating the Deletion Icon on the BindingNavigator.  I want the user to confirm that the deletion should go forward after clicking on the Delete Icon.  If the user says NO, then there does not appear to be any way to prevent the deletion in code.

So the only way I can see is to set the BindingNavigator.DeleteItem to (none).  However, if the user desires to let the deletion occur, what code will accomplish that for a single selected record in the DataGridView?  (MultiSelect = False in this app.)

The BindingNavigator has a property called 'DeleteItem'.
Change this property from 'BindingNavigatorDeleteItem' to '(none)'.
You can then delete the item (after confirmation) by using the BindingSource.RemoveCurrent method.


 Private Sub BindingNavigatorDeleteItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorDeleteItem.Click
        If MessageBox.Show("Do you really want to delete?", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1) = Windows.Forms.DialogResult.Yes Then
            YourBindingSource.RemoveCurrent()
        End If
    End Sub
