EDK Web Controls - Unique Control IDs

Question

After following the EDK Web Controls Developer Guide and making all the control IDs unique by appending the PortletID, the LinkButton controls in the portlet lose their OnClick Event Handlers.
The portlet works perfectly when not modifying the ControlIDs.
If I comment out all the portal specific code, modify the ControlIDs, and run in a standard web page, I also lose the Event Handlers.Any suggestions....

You can do it this way but you need to be careful when you do it (otherwise the control won't find it's state in the viewstate). I'd recommend changing the ClientID property - this will only affect how it gets rendered on the page, not how ASP.NET treats it.
Jonathan,
Here is the code below. I cannot modify the ClientID because the property is read-only.
privatevoidUniqueControlIDs(Control control)
foreach(Control ChildControl incontrol.Controls)
if(ChildControl.ID != null)
ChildControl.ID += PortletID;
UniqueControlIDs(ChildControl);
protectedoverridevoidOnPreRender(EventArgs e)
base.OnPreRender(e);
UniqueControlIDs(this.Page);
