Hi Telerik support team;

We have a web page which is opening a modal radwindow.  This radwindow loads another aspx page.  In the modal popup, a search is done and the search results are shown in a radgrid.  When a row is clicked on the radgrid, then the window closes and passes values back to the calling page and populates a text box.

The problem is that on the popup, if the search returns about 5000+ rows, and if one of the rows is clicked, then window closes but causes a javascript endless loop which in IE produces a dialog that says "Stop running this script? A script on this page is causing your web browser to run slowly.  If it continues to run, your computer might become unresponsive."  Could you please suggest a fix for this?  I have attached the javascript code on the calling page and the lookup page loaded in the radwindow.  Thanks in advance,

Meera

Calling Page:

Js code:

function openRadWindow(windowname) {

var accPage = '<%=Page.ResolveUrl("LookUpProducts.aspx") %>';

var txthiddenproduct = document.getElementById("<%= hiddenProductName.ClientID %>");

txthiddenproduct.value =

"";

var oWnd = radopen(accPage, "Product Lookup");

oWnd.add_close(clientClose);

oWnd.setSize(920, 600);

oWnd.set_modal(

true);

oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Resize + Telerik.Web.UI.WindowBehaviors.Maximize)

var y = document.documentElement.scrollTop;

var x = document.documentElement.scrollLeft;

oWnd.moveTo(x + 50, y + 50);

}

function

clientClose(sender, eventArgs) {

var arg = sender.argument;

sender.SetUrl(

"about:blank");

var products = document.getElementById("<%= acProductNames.ClientID %>");

var txthiddenproduct = document.getElementById("<%= hiddenProductName.ClientID %>");

if (arg) {

if (txthiddenproduct.value == "") {

products.value = arg;

txthiddenproduct.value = arg;

}

}

}

Popup page within radwindow:
Javascript code:

function RowSelected(sender, args) {

var productname = args.getDataKeyValue("ProductName");

if (productname === null || productname === "") {

productname =

"NoValue";

}

var returnvalue = args.getDataKeyValue("ProductName");

returnArg(returnvalue);

}

var oWnd;

function pageLoad() {

oWnd = GetRadWindow();

}

function returnArg(value) {

oWnd = GetRadWindow();

oWnd.argument = value;

// Set the updated value in button click

oWnd.close();

}

function GetRadWindow() {

var oWindow = null;

if (window.radWindow)

oWindow = window.radWindow;

else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow;

return oWindow;

}
