I have a set of 7 radcombobox controls on a page. When any one of them has their selected index changed I want the value of that combobox to "fill" to the right via a javascript function.

The combobox definitions are:

And the Bridge_Fill function is defined as:

Cases 1, 2, 3, 4, and 5 are essentially the same as Case 0 with one less combobox. The code is a little sloppy but that's not the problem.

When I change the first combobox, everything works and the other 6 comboboxes change their value correctly. It also works the second time. On the third time though the OnClientSelectedIndexChanged event does not fire and I cannot determine why. Any ideas?

I recently upgrade  to  2026.2.708 from 2025.1.416      

After upgrading there is a border appearing when I click on the menu item/radsitemap.    How do I remove the border?    Attached screenshot shows the border appearing.    The border is either dark blue or red depending on if I select or just right click the item, otherwise the border is not currently showing.    

my current css.  

        .RadSiteMap .rsmLevel > .rsmItem .rsmLink {
            color: #1c4259 !important;
            font-size: 12px !important;
        }

            #GDIV > .RadSiteMap .rsmLevel > .rsmItem .rsmLink:hover,
            .RadSiteMap .rsmLevel > .rsmItem .rsmLink:hover {
                color: #b31d3d !important;
                font-size: 12px !important;

            
            }


        #GDIV > .RadSiteMap .rsmLevel > .rsmItem .rsmLink {
            color: #1c4259 !important;
            font-size: 11px !important;
            line-height: 12px !important;
         
        }

            #GDIV > .RadSiteMap .rsmLevel > .rsmItem .rsmLink:hover {
                color: #be1d3d !important;
                font-size: 11px !important;
                line-height: 12px !important;
             
            }

        .RadMenu.RadMenu_Context.higherMenu {
            z-index: 2147483647 !important;
        }

        .RadMenu_Default .rmRootGroup .rmFocused > .rmLink {
            border-color: transparent !important;
            box-shadow: none !important;
        }

Thanks,   

I have a page with multiple RadHtmlCharts onit which generates following errors:

Hi,

I'm trying to download the UI for ASP.NET AJAX trial installer.

When I click Download Free Trial, I'm redirected to a request form instead of receiving a download link. I submitted the request, but I haven't received any response or email with the installer.

Could you please let me know:

• Is there any other way to obtain the trial installer?
• How long does it typically take to receive the download link after submitting the request?
• Is there a direct download page available?

Any guidance would be appreciated.

Thank you!

After receiving the email from Progress titled "Action Required: Security Vulnerabilities for Telerik UI for ASP.NET AJAX" regarding a security vulnerability in the RadAsyncUpload control, I updated my nuget packages to the latest version:  2025.3.812.462 --> 2026.2.708.462.  Everything else in the update is working successfully except for any page in which the RadAsyncUpload control lives.  

When the page loads, I receive the following error:

Another application updated to the latest version using the RadAsyncUpload works perfectly fine.  After researching, I discovered that my "broken" application is session-less, and my other application (which updated successfully) had no issues whatsoever.  In the previous version, 2025.3.812.462, RadAsyncUpload worked perfectly with a session-less application.  I've since had to implement session in order to resolve both the page load issue and the security vulnerability for the RadAsyncUpload.

If your worksheet contains repeated records, you can either use Excel's built-in Remove Duplicates feature or a more advanced utility for greater control. The advantage of specialized software is that it allows you to define exactly how duplicates should be identified.

You can compare selected columns, remove duplicate records, and retain only unique entries while preserving the workbook's original structure and formatting.

Hi,

After updating to 2026.2 the layout of the spinbuttons changed. See attached screenshots, Any idea what causes this?
