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;
}
