Hi, 

I have used RadListBox control at many places in my project. The issue is intermittent, especially in IE10 and IE11.
The icons(rlbButton) appears blank i.e. without the arrows etc... Please provide a solution or a workaround for the same.
Please find attached the snapshot.

Thanks

I'm trying to have my controls get updated when the SkinChooser changes value to some other Skin (I'm using the embedded DLL skins provided).

in my code behind: 

fairly basic stuff, but my controls don't update with the newly selected skin ... what am I missing?

Cheers, Rob.

Hi, I'm using a treeview control on my application, and in my Dev, Test and UAT environments, I'm seeing the arrows for the expand/collapse icons.  However, on my Prod environment, which theoretically is the same as my UAT environment, I see the plus/minus signs.

Looking at the css coming down as a WebResource, on UAT, I see:

/* START Telerik.Web.UI.Skins.TreeViewLite.css */

But on the css that comes down from Prod, I see this:

/* START Telerik.Web.UI.Skins.TreeView.css */

I've gone through my code trying to figure out why, can't see anything.  Also, after looking through documentation on this site, I have added the following lines to my web.config, but with no change:

   <appSettings>

      ...
      <add key="Telerik.Web.UI.RenderMode" value="lightweight" />
   </appSettings>

...

   <system.webServer>

...

      <httpProtocol>
        <customHeaders>
          <add name="X-UA-Compatible" value="IE-Edge" />
        </customHeaders>
      </httpProtocol>
   </system.webServer>

Is there any other things I should know about my production environment that might be causing this behavior?

I'm currently using version 2017.1.228.40 of the Telerik assemblies &  running .NET 4.5.1

Thanks,

Phil

Is there any mechanism in the Spreadsheet classes that would allow me to insert or extract an object file from a spreadsheet?  I cannot seem to locate anything on the matter in the API documentation or on the objects when debugging.

Thanks,

I am looking for the most efficient way to load data outside of the main datasource control into the grid edit formTemplate. In the past I have loaded data for a asp gridview on the edit command and would use the findControl to bind to the child datasource. I do not see an example for the FormTemplate mode only for the GridTableView.DetailTables. Is this possible and is there an example on the correct way to do it?

Thanks in advance

We're looking for a simple way to turn a workbook to read-only.

Since the workbook includes some 11 sheets, each with a different number of rows and columns we cannot use the spreadsheet range setting (range.set_enabled(false)).

We tried using the workbook.Protected parameter in code-behind, but the "Protected" parameter is somehow not accepted.

Any tips would be appreciated.

I've search thru all the thread regarding RadAlert not working and I still can't figure out why I get nothing at all, no errors in code, no exceptions triggered, nothing.

Here is my code:

and code behind 

I also tried without the callBackFn which was pulled direction from your documentation sample.

Any suggestions?

Cheers, Rob.

We use the Cloudflare service for a site that uses RadEditor controls on several pages. When the Cloudflare web application firewall is turned on, a POST with HTML in a RadEditor control triggers several XSS and SQL Injection rules in the web application firewall. There were so many false positives that the web application firewall was immediately turned off.

Does anyone have experience resolving this issue by either changing the settings/configuration of the RadEditor controls, or by tweaking the Cloudflare Web Application Firewall rules?

Please note that I'm not suggesting that this is a flaw in the RadEditor control. The RadEditor provides an amazing amount of functionality.

Thanks
