Hi,
Custom events in a custom data bound control are not firing in DataRepeater control. When I debug it I found that the DataRepeater Control recreates the control using Activator.CreateInstance and Copies the Properties and Events. In my case copying events doesn't copy the custom events that I hooked in.
For example
public class MyClass : Control { public event EventHandler MyEvent;
protected virtual void OnMyEvent() { if(this.MyEvent != null) { this.MyEvent(this,EventArgs.Empty); } }
private int selectedIndex= -1; public int SelectedIndex { get { return this.selectedIndex; } set { if(this.selectedIndex != value) { this.selectedIndex = value; this.OnMyEvent(); } } } // // DataBinding stuff goes here //
}
public Form1() { InitialiseComponent();
ArrayList list = new ArrayList(); list.Add("one");
this.dataRepeater1.DataSource = list; // One Repeater
MyClass test = new Myclass(); test.DataSource = GetDataTable();
this.dataRepeater1.ItemTemplate.Controls.Add(test);
test.MyEvent +=new EventHandler(test_MyEvent);
}
// This Event should fire when selected index of Datatable is changed and is firing when placed directly in the form and not firing when place in DataRepeater control/////////////////////// private void test_MyEvent(object sender, EventArgss e) { // This event is not fired/////////////////////// }
private DataTable GetDataTable() { ..// Create a data Table and return }
Any help Appreciated.
Thanks,
