RadGrid Custom Filtering Not working

[Kannan]

Hi,

I am using Radgrid with Filtering options. In that i need to make a column filter to customized drop down. I am using this telerik version 2011.2.726.35. I have used the same example which is provided in this link http://www.telerik.com/help/aspnet-ajax/grid-filtering-with-dropdownlist.html .  But i am getting an error like unknown tag customFilter. customFilter is the prefix which is used in registering class file. And the class name is FilterColumn.

This is the code which i used for registering and in telerik columns.
<%@ Register TagPrefix="customFilter" Namespace="TestProject.Common"  %>

<customFilter:FilterColumn DataField="TaskStatus" UniqueName="TaskStatus1" FilterControlWidth="80px" HeaderText="Status"></customFilter:FilterColumn>                   

Please any one help me to get rid of this error.

Thanks & Regards
Kannan

Hi,

 Please make sure the custom class is defined in a separate file in the App_Code folder of the web site. Then you you reference it in the suggested way:

<%@ Register TagPrefix="custom" Namespace="MyNamespace1" %>

Hi Marin,

Thanks for your reply.

I have found another solution like giving assembly name while referencing. And that worked for me.

<%@ Register TagPrefix="custom" Namespace="MyNamespace1" Assembly "Project1"%> 


Thanks a lot once again
