Hi Everyone

just been playing around but cant seem to find any way to hook the WebDropDown to a web service on the client side like the ajaxtoolkit autocompleteextender see link and example  below:

 http://www.asp.net/ajaxlibrary/ajaxcontroltoolkitsamplesite/autocomplete/autocomplete.aspx 

Example:

<AjaxToolKit:AutoCompleteExtender ServiceMethod="ExampleMethod" ServicePath="~/AutoComplete.asmx" MinimumPrefixLength="1"
 CompletionInterval="10" TargetControlID="txtbxExample" ID="AutoCompleteExtender1" runat="server">
</AjaxToolKit:AutoCompleteExtender>

i would want the WebDropDown to populate after a number of characters had been entered unlike the example given by infragistics which binds on the server side see link below:

http://help.infragistics.com/Help/Doc/ASPNET/2011.1/CLR4.0/html/WebDropDown_Binding_WebDropDown_to_a_Web_Service.html

i would also want to group the items if possible

any help would be appreciated

Thanks
