Hi ,

I have one telerik modal popup window in which I am loading some event, after session timeout occurs, page in the modal pop window redirects to login page.

What I want achieve is, On session Expiration modal window should disappear and parent page should be redirected to login page.

Any views on this.... attached is the snap?

Hi,
I have an issue when running RadGrid in IE8 where the columns are not aligned properly when I group on one or more columns.  When I don't have any grouping in the grid, then the column headers are aligned correctly with the rows.  See Screenshot 01.jpg.  However, if I put a column in the 'group by' then the column headers are off.  See Screenshot 02.jpg.  Please advise if anyone has seen this before and if there is a resolution.

Hi Guys,

I have a rad rotator in a rad notification. This rad notification is included in a panel which can be updated after an ajax request. If so, the radrotator is not displaying the content anymore.
i saw that 
http://www.telerik.com/help/aspnet-ajax/rotator-coverflow-animation-and-ajax.html
saying you need to register the script in the code behind.

I have not been able to translate my parameters to have a persistent radrotator. Could you please help me? here is my radrotator:


Thank you

Hi,

Bit of a long shot this, but here we go. It's more of a generic Javascript issue than a problem with the Telerik controls, although I am using the controls.

I have a problem where when I try to $find a telerik control in an ASP.NET user control it is always returned as null. However, if I $get this control using the same ID then a HTML Input Object is returned. I've tried using the $find function on a stand alone page and it works fine with either:


The ID of the control I am looking for is rendered like this in the HTML:

ctl00_ucRTKTemplate_ctl04_ctl00_cmFileView

ucRTKTemplate being an ASP.NET user control that loads another ASP.NET user control that contains the Telerik context menu I am attempting to find. If I type the above ID directly into the $find function then I do find the control, but obviously I would like to be able to find this control dynamically.

Any ideas?

Thanks,

Michael

Hi,
    I got licensed version of 2013 Rad Grid. While it works fine in a test project. When I use the same demo code, On databind, in my application, I get an exception like below. I checked and rechecked any differences between the demo project and my application. There seems to be no difference at all. I used the same dummy datasource like in the Demo project, still I get the error. Any help is appreciated.

I have a RadNumericTextBox in a RadGrid.  I'm using the OnClientValueChanging event to validate the numeric value (I have to do a calculation).  It works great, except when I'm editing in the RadGrid, and I change the value to an undesired value, and I click the Update ImageButton, the OnClientValueChanging event is not raised.  It just posts back and updates the row.

Any idea how I can raise the OnClientValueChanging event before the Update button posts back?

Hi,

Hello,

I'm using a client template in a search box. The box is bound to a web service and the template looks like this:

Things are working just fine in Chrome and IE but, in Firefox, I'm getting an error in firebug that the DataItem is not defined:

Sys.InvalidOperationException: Sys.InvalidOperationException: Error rendering template: DataItem is not defined. There's no reason why the web service would return the dataitem for Chrome and IE but not firefox... right?

Any ideas?

Thanks,

Mike

When switching between Design and Html views, html that contains a newline in a tag's attribute value, the tags <> will be converted to &lt; &gt;

This behavior can be replicated in the current RadEditor Demo

Initial Html:
<html>
    <head>
    </head>
    <body>
        <div class="class_a
        class_b">
        Hello
        </div>
    </body>
</html>

After switching between Design and Html modes its converted to:
<html>
    <head>
    </head>
    <body>
        &lt;div class="class_a
        class_b"&gt;
        Hello
    </body>
</html>
