Disable or stop AutoCompleteExtender (Javascript)

To disable or stop the AutoCompleteExtender from running or calling its service to load auto suggested list, (Using Javascript)

Its very simple

-Set the BehaviorID property for the AutoCompleteExtender

<ajaxToolkit:AutoCompleteExtender
   runat="server"
   ID="autoSuggest"
   TargetControlID="SearchBox"
   ServiceMethod="GetSuggestedList"
   ServicePath="~/_Services/AutoSuggest.asmx"
   MinimumPrefixLength="2"
   CompletionInterval="1"
   EnableCaching="true"
   CompletionSetCount="10"
   CompletionListCssClass="AutoSuggestSearch"
   CompletionListItemCssClass="listItem"
   CompletionListHighlightedItemCssClass="highlightedListItem"
   BehaviorID="autoSuggest"
     />

Then using javascript just write:

function selectType()
{
   var a = $find("autoSuggest");
   a.set_serviceMethod('');
}

By setting the service method to empty, the autosuggestextender will not find the service to call and will stop working
