16.        </div>
17.    </InlineInsertTemplate>
18.    <AdvancedForm Modal="true" />
19.</telerik:RadScheduler>

In C# within the "JobNumSelected" method I can type RadScheduler1 and it will be a valid reference to the object. I cannot type RadDropDownList1 and have it be a valid reference I can only see the base object not the instance I created. If I move the RadDropDownList object outside of the RadScheduler I can reference it just fine. 

I'm trying to make a scheduler where a user can select a job and a phase and that would show them being busy for whatever time period they selected.
