AsyncUpload Handler Exeption

Hi all,
I am using the latest version of async control with a handler to upload user images.

The handler code is inside a try...catch statement:

    protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration                      configuration, string tempFileName)
   {
       SampleAsyncUploadResult result = new SampleAsyncUploadResult();
       result.ImageUri = string.Empty;
       result.ImageID = 0;
        try
        {
             .... process image stream......
        }
       catch (Exception e)
        {
           Logger.Error("Error in IAsyncUploadResult Process.....", e);
           result.ImageUri = string.Empty;
           result.ImageID = 0;
        }
       return result;
    }

However, I never see the above error in my log files... Instead I often see the following error, which is logged on the application error even of global.asax:

ERROR 2011-07-19 19:18:47,994 - Application Error by user: 
Telerik.Web.UI.AsyncUpload.AsyncUploadHandlerExeption: RadAsyncUpload handler is registered succesfully, however, it may not be accessed directly.
   at Telerik.Web.UI.AsyncUpload.RequestData..ctor(HttpContext context)
   at Telerik.Web.UI.AsyncUploadHandler.EnsureSetup()
   at Telerik.Web.UI.AsyncUploadHandler.ProcessRequest(HttpContext context)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Can you please help me troubleshoot this problem....

Thank you for your time,
Panagiotis.

customized file upload popup window

Hi Telerik Team,

We try to find a way to customize the file upload control in the Editor's *.manager. The idea is we want to make two tabs in the file upload window, one is select files from local computer which is the same function as now and we also want to add a new tab for external applications. We will implement the new tab feature by ourselves.

We are struggling to find a solution to add two tabs and implement our customized feature in file upload control. Could you please help us out ?

The interface should look like what we see in the attachment.

Thanks in advance!

Must call clearSelection before clearItems() in latest Q1 '14 release

I think a bug might have cropped up into the latest Telerik release (Q1 '14, April SP release). Typically, when clearing and adding items to a combo box client side, script like this has worked:

var combo = $find("MyComboList")
combo.trackChanges();
combo.clearItems();
// code to add items
combo.commitChanges();

However, with the current release, the above code will leave the previously selected item in the combo box as well. In order to remove it, you have to manually clear it, so the above code now becomes this:

var combo = $find("MyComboList")
combo.trackChanges();
combo.clearSelection(); // ensures that the current selected item will be removed as well
combo.clearItems();
// code to add items
combo.commitChanges();

This seems like a bug to me. Can someone from Telerik confirm?

Thanks,

Mike Oliver
