how can i create a custom RadGrid Filter?
in other words i have a gridview, and i want to create a custom Filter on a certian GridBoundColumn. i know that i should use this:

<

 

telerik:GridBoundColumn DataField="ID" HeaderText="ID"

 

 

<FilterTemplate>

 


</

 

FilterTemplate>

 

 

</telerik:GridBoundColumn>

but lets say i have a listbox inside the above filterTemplate. how can i add the FilterButton (that shows equalto,notequalto.... when clicked) so a user can choose an item from the listbox, and filters accordingly.

i have already seen this link:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx
but this link adds a dropdownlist to the GridBoundColumn Filtertemplate, but it filters when the selectedValue of the dropdownlist changes. what i need is the same filterButton that appears by default (that contains the filter criteria when selected)
