Hi, I'm using RadGrid, to show a list of transactions. In one of the scenarions, we have to show nearly 2000 records to the user at the same time, on click of search button.

When we execute this functionality in IE8, IE9 it works perfectly and the page is rendered in 5-6 seconds, but if we use the same code in IE7 then the page takes more than 30 seconds to render.  Once the page is loaded at client side, if we try to scroll the page then the browser hangs and we have no other option but to kill the browser process.

I am not sure why there is so much difference in performance in IE7 and IE8.

Any assistance in this problem would be of great help.

 
Thanks
Nilesh Patel.

When I try to upload a file that is open in Excel, the upload fails.  I added a handler for OnFileUploadFailed that will display the error message - "IO.IO_SharingViolation_File". However, after the user closes that alert box, then there is an unhandled exception thrown by the control.  On my dev machine, I get the boxes asking if I want to use Visual Studio to debug the script error.  On another users machine, what they see is the file to be uploaded with the red light and the X Clear button.  When they click Clear, the file disappears but the text box and Browse button do not reappear, they are still invisible.  I assume this is because of the unhandled exception.

I found one other post here that was a similar problem, but the only response was that it was a known issue with Silverlight and to add "Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function () { return false; }" to the page.  However, I notice that doing that makes the control ignore its AllowedFileExtensions property, so that there is no filter for file types when browsing for a file to upload.  However, it will upload a file open in another app.  But it is not acceptable to not have that type filter.  I tried setting it in the page_load event in code behind but no success.

I am not very good at javascript; is there a way to catch this exception thrown by the control so that I can handle it gracefully or at least get the browser to ignore it?  Or is there another way to fix or work around this?

Hi

I have a number of rad windows in the page which pull a page from a related external site with video
content. Instead of a blank window waiting for the external page, I would prefer a text message or a default
loading panel as for radAjaxPanel for example, but I can't see how to make this work.

I have seen reference in posts to a default loading panel but see no property of the window that relates to that.

Help would be appreciated!   (Using Q2 2010 and asp.net 4.0 on this site)

Thanks

Clive

My current window is 
<telerik:RadWindow ID="RadWindowVid" runat="server" OpenerElementID="div495" Width="560px"
        Animation="Fade" Behaviors="Close" VisibleStatusbar="False" Title="Bessacarr Cameo 495"
        Skin="WebBlue" OnClientClose="OnClientClose">
</telerik:RadWindow>

Hello,
For some reasons I have to build my gridview programmatically. 
One of the column is build like this: 

  Dim myColumn As GridBoundColumn
        myColumn  = New GridBoundColumn
        myColumn .DataField = "myValue"
        myColumn.HeaderText = "Value"
        myColumn.UniqueName = "myValue"

The gridview is editable. When I click on the edit button (and an input text appears) I want to get the input id with javascript. 
How can I do that? 
Thanks in advance

I have a problem.
I need to create a dynamic image button and assign the event "click"  on a node of a "treeview", the problem is that when you click the image button disappears and never calls the event "lkbEliminar_Click".
    ImageButton lkbEliminar = new ImageButton();
      lkbEliminar.ImageUrl = "~/images/delete.png";
       lkbEliminar.ToolTip = "Eliminar Documento";
        lkbEliminar.Click += new System.Web.UI.ImageClickEventHandler(lkbEliminar_Click);  
      nodoHijoMenor.Controls.Add(lkbEliminar);
         nodoHijoMayor.Nodes.Add(nodoHijoMenor);
 
  protected void lkbEliminar_Click(object sender, ImageClickEventArgs e)
        {
            string x = "asdas";
            x = x + "asdsa";
 
           }
