Good afternoon,

I'm currently running Telerik UI for ASP.NET AJAX R3 2023.  I am using the RadAsyncUpload with a AsyncHandler.ashx to copy the file to a RadUploadTemp on a file share.

This has been working perfectly for ages but recently large file updates have been failing e.g. a 2.1 GB file failing at 61%.  I'm being told this is due to a TCP Zero Window issue.

I assumed the chunked upload mechanism mitigates the issues caused by TCP window size restrictions, which can cause slowdowns or failures when uploading very large files in a single request. I am setting the upload ChunkSize value to 4194304.

I have the following settings in web.config:

  <system.web>    
    <httpRuntime maxRequestLength="2097151" executionTimeout="18000"/>
  </system.web>

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="4294967295"/>
      </requestFiltering>
    </security>
  </system.webServer>

Have you got any ideas as to why it might be failing for larger files, or what I can do to the configuration to prevent the TCP Zero Window error by pausing data transmission until the receiver is ready to accept more data?

Kind regards,

Richard

1. If there is any workaround we can implement using the current RadMenu to meet this requirement?
2. Whether there is an estimated timeline for when the RadMenu will support WCAG 2.2 natively?

Dear,

I use RadNumericTextBox with these options: 
 MinValue = 0
 MaxValue = 9999999
 NumberFormat.DecimalDigits = 2
 MaxLength = 10
 ShowSpinButtons = true

I see specific problem when I use any decimals. When I click on arrows (or type keyboard arrows) it increases/decreases by 1, but sometimes it stops on specific number (e.g. for 8.42 arrow down do nothing or for 63.42 arrow up doesn't work). I think there is a problem with javascript rounding and 8.42 - 1 is sometimes like 7.419999999999. It looks like a inner bug of the component.

Is it possible to format number first and make validation of length aftewards?
Is there any workaround for it?

Thank you

Hi

Im using visual studio 2019 .netframework using c#

I have a telerik Rad grid that is in Batch Mode and works great.  Within rg_SalesPlan_BatchEditCommand it goes through each edited row and does an update to the database, if one of the records fails to update the error message is added to a variable which collects any other errors. One finished in the foreach loop if any errors occured a popup alert is displayed with the errors.

My problem is once I click OK to the alert to acknowledge the errors, the grid refreshes but Im unable to continue editing any other rows, If I click on  a row nothing happen, until I click on Cancel or Save Changes button, then the grid goes back to normal.

Whats the best way to refresh the state of the grid so its back to normal please? 

Thanks

Good morning

Was there issues with any recent updated to Telerik?  I have just noticed that in Design View of my visual studio project, none of my Telerik RadGrds are displayed anymore.  Instead I get a control box on each grid with the error "Sysem.NullReferenceException"

Hi, I recently received a new laptop at work.  I was eventually able to compile and run both of my 2 applications in localhost, and deploy one of them to Dev and Prod.  However, I am having problems deploying my 2nd application. 

Again, it works fine in localhost.  When I deploy to the Dev environment, I get the error:

Could not load file or assembly 'Telerik.Web.UI, Version=2018.1.117.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The version my reference points to is 2018.2.516.45.  So I don't know where the 2018.1.117.45 version is coming from, or why it is attempting to load this version.

Yes, I KNOW that this is an old version. If need be, I can probably upgrade to a newer version.  But if I can't figure out the version mis-match now, I think I will have the same problem with a newer version.  

Any help is appreciated.  

Thanks!

I'm using a Telerik RadGrid with nested grids (using NestedViewTemplate) inside an ASP.NET Web Forms page. I've enabled scrolling with AllowScroll="true" and UseStaticHeaders="true", and set a fixed width for the outer container with horizontal scrolling.

The issue is that when I scroll horizontally to the right and then expand a nested row, the inner RadGrid (in the nested view) does not align properly or its scroll resets to the left. I want both the parent and child grids to stay aligned and scroll consistently, especially when expanding/collapsing rows.

Has anyone faced a similar issue or found a good way to synchronize scrolling between parent and nested grids?

I have web projects that I am trying to update with the new 2025 Q1 assemblies and am getting a build error of the TelerikLicense.vb file.

I followed these instructions:

1. Search for AJAX.
2. Click on View key next to the Progress® Telerik® UI for ASP.NET AJAX.
3. Copy the Script Key.
4. Add a file to your project, e.g. TelerikLicense.cs (for VB projects add TelerikLicense.vb).
   • In case of ASP Web Site solution, add the file to the App_Code folder.
5. Paste the Script Key into the file.
6. Build the project.
