I have been using the Google based filtering example (http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandcombo/defaultcs.aspx?product=grid) to extend the GridDropDownColumn to support a RadComboBox rather than text filter. I am looking for a way to utilize the AutoCompleteSeperator to allow to multiple value selection. So the user could pick 3 items from the list and get a result set of any rows with any one of those columns set. Is this possible? My working code is bellow, it follows the Google example closely.
/// Summary description for DDLColumn
public class DDLColumn : GridDropDownColumn
//RadGrid will call this method when it initializes the controls inside the filtering item cells
You can accumulate the filter and trigger it at once, for example.
Give this approach a try and let me know how it goes and if any other questions arise.
All the best,
the Telerik team
