    I am trying to use the  Telerik ComboBox control and  it keeps throwing me "stop running this script". This happens whenever I select  the item from the  dropdown or while typing and  changing on the  combo inputbox. I have  read the  performance optimization telerik web article but that has not helped me in anyway. At any given  time the  number of combo items could be around 1500 - 2000. 

    I have added the  Telerik RadComboBox control as below, 

     <telerik:RadComboBox ID="radComboCityNames" runat="server"  EnableLoadOnDemand="true" OnClientBlur="" OnClientFocus=""
       OnClientItemsRequesting = "StopRequest" onitemsrequested="radComboCityNames_ItemsRequested" skin="Default" 
       MarkFirstMatch="false" AutoPostBack="false" EnableItemCaching="true"  EnableEmbeddedScripts="false" EnableViewState = "false">

    And on the  ItemsRequested handler I have  coded as follows, 

    RadComboBox combobox = (RadComboBox)sender; 
    string text = string.Format("{0}%", e.Text);

    DataTable dat = dt.GetCityNamesTable(1, text);
    combobox.DataTextField = "cityname";
    combobox.DataSource = dat;

    Script used ,

        function StopRequest(combobox) {
            var combo = $find("<%=radComboCityNames.ClientID  %>");
            if (combo.get_text().length < 1) {
                return false;
            else {
                return true;

    Your assistance is much appreciated. It seems may people have  raised this but none has got a proper solution.! :(

    Hello Subbaraya,

    Do you receive this error in particular browser or in all of them? Also please change you event handler function as following:
    function StopRequest(sender, args) {
                if(sender.get_text().length < 1) {

    Kind regards,
