Examples
The following example demonstrates how to cancel a deletion in the DeletingItems event handler.
Private Sub DataRepeater1_DeletingItems(
ByVal sender As Object,
ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterAddRemoveItemsCancelEventArgs
) Handles DataRepeater1.DeletingItems
' Check whether the user is a supervisor.
If My.User.IsInRole("Supervisor") = False Then
' Cancel the deletion and display a message.
e.Cancel = True
MsgBox("You are not authorized to delete.")
End If
End Sub
private void DataRepeater1_DeletingItems(object sender,
Microsoft.VisualBasic.PowerPacks.DataRepeaterAddRemoveItemsCancelEventArgs e)
{
// Check whether the user is a supervisor.
ClientRolePrincipal rolePrincipal =
System.Threading.Thread.CurrentPrincipal
as ClientRolePrincipal;
if (rolePrincipal.IsInRole("supervisor") == false)
{
e.Cancel = true;
MessageBox.Show("You are not authorized to delete.");
}
}
