"This is an invalid webresource request " error on Telerik grid load

Hi,

We are using Telerik grids in our website built on ASP.Net 4.0. We are getting an internal exception as:

System.Web.HttpException (0x80004005): This is an invalid webresource request.
   at System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext context)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)}

This exception is thrown every time any grid loads. Though, this is not affecting grid's working but we want to track at which point this exception is thrown and how much this can affect our website's performace.

Please help us regarding this.

Is there anyway to get the data from the ItemTempate (All the information is coming from the same datasource) to the export. (VB Example if you can).

WeekView support on a WCF Bound Scheduler with Date Grouping

I have a Scheduler with the appointments and resources bound from a WCF service.

According to this page on the help site I should be able to use WeekView and MonthView as long as I use ResourcePopulationMode="ServerSide".

With this setting in place and the scheduler set to show WeekView by default I get a server error saying "Date grouped WeekView is not supported when using Web Service binding" (ysod.png)

Which of these is correct? Should I be able to use WeekView and MonthView with date grouping or not?

Also, if I set the scheduler to show DayView by default and then click on the WeekView button on the scheduler it renders as attached (halfrender.png) but also gives an error in Visual Studio (vserror.png)

I am using Telerik.Web.UI.dll version 2011.3.1305.40

Thanks

Simon

RadMonthYearPicker without input field

Is there a way to disable, or rather replace the input field of a RadMonthYearPicker with a label? Or just show the image?

I'm trying to create a GridView that emulates a calendar since the functionality I need doesn't exist with the RadCalendar and I'd really like to emulate the way the RadCalendar uses the paged month/year label as the trigger to open the MonthYearPicker. Is there anyway I can accomplish that myself?

RadContextMenu as a popup, controlled by serverside codebehind..

ASPX
<script type="text/javascript">
//<![CDATA[
function showMenuAt(e) {
var contextMenu = $find("RadContextMenu1.ClientID");
var x = parseInt($get("contextX").value);
var y = parseInt($get("contextY").value);

if (isNaN(x) || isNaN(y)) {
alert("Please provide valid integer coordinates");
return;
}

contextMenu.showAt(x, y);

$telerik.cancelRawEvent(e);
}

function showMenu(e) {
var contextMenu = $find("RadContextMenu1.ClientID");

if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget))) {
contextMenu.show(e);
}

$telerik.cancelRawEvent(e);
}
//]]>
</script>

  <Telerik:RadContextMenu id="RadContextMenu1" runat="server"
         EnableRoundedCorners="true" EnableShadows="true">
                <Items>
                    <Telerik:RadMenuItem Text="Trees" />
                    <Telerik:RadMenuItem Text="Sunset" />
                    <Telerik:RadMenuItem Text="Mountains" />
                </Items>
            </Telerik:RadContextMenu>

And from VB.net codebehind I try to SHOW the popup.
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "reloadamchart" & Guid.NewGuid.ToString, "showMenu(e);", True)

Another tricky part is that Google Map right_click gives you map coordinates lat/lng insted of the client pixel where the right click took place. I gues all clients will have different screen resolutions making this very difficult ?

'This is example of what I would like to accomplish using RadContextMenu.

and all is ok
but why I have to inlcude the link to jquery.js in the head section of the page ?
( some like <script src="/js/jquery-1.6.2.min.js" type="text/javascript"></script> )
if telerik use jquery - why this is not usable from all the code in the page?
I test it with this simple script
if (jQuery) {

}
If I don't inlcude jquery in the head section the alert don't fire
thanks in advance
