Hello adel,

You will find the required information along with a sample at the following blog post:
http://blogs.telerik.com/vladimirenchev/posts/08-12-03/new_feature_asp_net_ajax_grid_filter_template.aspx

In addition, do keep in mind that you need to set EnableLinqExpressions=false in order for the filtering to work with a column bound to an Enum type of object.

Hope it helps.
