User Control implementing IScriptControl with several Rad controls

[Troy]

I have a user control that I've implemented IScriptControl on to allow the addition of a client side api to the control.  The user control contains a few RadComboBoxes.  Everything is almost working, however, during the initial page load my client side dispose method is called, which in-turn causes a client side error in the RadScriptManager client side code in CreateCallback with error a is undefined.  

We have a master page that is being used, which contains the RadScriptManager.

I'm sure I'm just missing something, but any help you can provided would be greatly appreciated.

After further debugging, the error appears to occur in Sys.UI.Control=function(a){Sys.UI.Control.initializeBase(this);this._element=a;a.control=this}

I am new to using IScriptControl, so please forgive the shortcomings.

It appears that the element passed to my javascript constructor is null because the clientID of my user control does not actually end up on the page.

Can someone please help me out here?

I have resolved the issue.  The issue was that the clientId for the UserControl is not rendered to the page, only the child items.  So, the $find could not find my userControl by it's clientId.

I simply added code the Render method to wrap the control in a div with the UserControl's clientId as the Id.
