I looked at the custom filter demo at : http://demos.telerik.com/aspnet-ajax/filter/examples/customeditors/defaultcs.aspx?#qsf-demo-source 

I followed everything that is being said in this demo. I copied the code and pasted it in my webform. However, I am getting lots of errors.

Does anybody have a working example (ie. zip file or solution file) of this demo?

Thanks
