First solution:

Just expose a public property in UserControls_CategoryDropdown user control and return dropdown list via this property instead of finding the control.

Second Solution: All server controls converted in the html control during the page rendering on client side so controls id changed to. Therefore when you are finding the control through the id which given in code it will not available on client side.
- For actual id, view the source page the see the actual id generated on client side then try to find through that id.
- If you are using Framework 4.0/3.5 then set attribute "ClientIDMode=Static" of Dropdownlist then you will get your actual id ("ddlcategory") on client side.
