catch (DatabaseNotEnabledForNotificationException ex)
{
  enabledTables.Visible = false;
  disableTable.Visible = false;
  enabledTablesMsg.Text = "Cache notifications are not enabled in this database.";

  tableName.Visible = false;
  enableTable.Visible = false;
  tableEnableMsg.Text = "Must enable database for notifications before enabling tables";
}

Catch ex As DatabaseNotEnabledForNotificationException
  enabledTables.Visible = False
  disableTable.Visible = False
  enabledTablesMsg.Text = "Cache notifications are not enabled in this database."
