Examples

The following example demonstrates how to handle the NewItemNeeded event. It assumes that you have a DataRepeater control named DataRepeater1 that has its VirtualMode property set to True, and that you have a data store for a data source named Employees.

Private Sub DataRepeater1_NewItemNeeded(
  ) Handles DataRepeater1.NewItemNeeded

    Dim newEmployee As New Employee
    Employees.Add(newEmployee)
    blnNewItemNeedEventFired = True
End Sub
private void dataRepeater1_NewItemNeeded(object sender, System.EventArgs e)
{
    Employee newEmployee = new Employee();
    Employees.Add(newEmployee);
    blnNewItemNeedEventFired = true;
}
