[Solved] jQuery chosen plugin not applied to AJAX Cascading DropDownList in ASP.Net

I implemented AJAX cascading drop down in one of my project. The code works too. But if I apply JQuery UI's .chosen() method for the drop downs the cascading functionality stops working. Is there any work around for this issue?

Source code for reference -

<asp:DropDownList ID="ddlSearchProduct" runat="server" ClientIDMode="Static" Width="99%"></asp:DropDownList>
<asp:DropDownList ID="ddlSearchItem" runat="server" ClientIDMode="Static" Width="99%"></asp:DropDownList>
<ajaxToolkit:CascadingDropDown ID="ccdItem" runat="server" Enabled="True" TargetControlID="ddlSearchItem" Category="Item" ServiceMethod="BindItemDetails"
    ServicePath="~/Webservices/CommonService.asmx" LoadingText="Loading..." PromptText="Select" PromptValue="0" ParentControlID="ddlSearchProduct" ClientIDMode="Static">
</ajaxToolkit:CascadingDropDown>

Thanks
