Telerik has introduced the Grid / Filter Template feature which enables you to add any control into the filter row for a particular columns.You can make use of this feature to add the combobox with checkboxes for the required column.
Here is just an outline of what you can do. Please modify to suit your requirement.
I have added a radcombobox with chekboxes in the filter template. On each checkbox click we loop through the items in the combobox and concatenate the checked item text. We can then fire an ajax request and pass the argument containing the datafield and checked values. In the server side you can set the Filter Expression for the column accordingly.
