stop running this script

[Subbaraya Prabu]

Hi 

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">
 </telerik:RadComboBox>

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;
combobox.DataBind();

Script used ,

    function StopRequest(combobox) {
        var combo = $find("<%=radComboCityNames.ClientID  %>");
        if (combo.get_text().length < 1) {
            combo.hideDropDown();
            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) {
                args.set_cancel(true);
                sender.hideDropDown();
            }
        }

Kind regards,
