Date filter in Radchart throwing exception in javascript

[Manishkumar]

Hi,

We are using Radgrid having date field colums with AllowFilteringByColumn="true" property.
While the page is loading we get this error 'ct100_ContentPlaceHolder1_GridName_gdtcSharedCalendar'  was not found. Could you please tell us where are we possibly going wrong.

Also because of this error, the page does not load properly and  the grid becomes distorted.
Here's our code:

can you please provide the solution for this ASAP. 

<telerik:RadGrid GridLines="None" HorizontalAlign="Left" BackColor="#EFF7FF" ID="gvDrilDown"
