This sticky thread lists known issues and breaking changes introduced in the UI for ASP.NET AJAX releases.


Q3 2011 (Version number: 2011.3.1115)

Problem: When adding items to OData-enabled controls (RadMenu, RadTreeView, RadListBox, RadComboBox) through design time erroneous markup is applied to the control:

<telerik:RadListBox runat="server" ID="RadListBox1">
    <Items>
    </Items>
    <WebServiceSettings>
        <ODataSettings InitialContainerName="">
        </ODataSettings>
    </WebServiceSettings>
</telerik:RadListBox>

Please note the added ODataSettings section. It will cause JavaScript errors on the page.

Solution: Remove the ODataSetting section and the issue will vanish. The problem is also fixed in the Q3 SP1 release, version number 2011.3.1305

When I run my project I'm getting this error

Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

In my web.config I checked that the version in the web.config is the same as the version I'm using in references

<assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2020.2.617.45" newVersion="2020.2.617.45" />

Hi,

Does anyone know where to find the EOL dates for each version, especially 2016.1.225.45 and 2020.1.219?

Thanks.

I have an old ASPX Web Forms application.  I am trying to pick the right update to replace the old Telerik UI for ASP.NET AJAX version 2014.2.724.40.  The application is build using .Net Framework 4.7.2.

I have downloaded TelerikUIForAspNetAjaxSetup, but all the options seem to be for the more modern .Net Core.  Where can I find the per-core library?

thank you

Philip

I've used Telerik for 15 years, or when it came out. I've stepped away from development as I moved up in ranks. Today, I'm going to develop an application. I purchased the software, installed it and opened Visual Studio. After opening Visual Studio, I selected "Telerik Web Forms Application" and clicked next. I selected a blank project from the Progress create new project screen. The app did it's thing and i was presented with a project with a Default.aspx. I tried to run it and it is nothing but errors, ( Unknown server tag 'telerik:RadStyleSheetManager'.)  (telerik, unknown tag prefix and so on) This has never happened in the past and I'm following Teleriks own project start. SMH. So much for quickly knocking out an application. Now I have to spend time trying to Unscrew Telerik's poor quality deployment and installation. SMH! So frustrating and annoying. 
So, what hoops do I need to jump through to get this working that was not done when I used Telerik to build this project?

Hello.

I need to check on each row of the grid if its checkbox is checked or not.

<tel:GridTemplateColumn HeaderStyle-Width="15px" UniqueName="gridTemplateColumnCheckbox">
                                    <ItemTemplate>
                                        <asp:CheckBox ID="chkItem" runat="server" AutoPostBack="false" CssClass="checkbox-item" />
                                    </ItemTemplate>
                                    <HeaderTemplate>
                                        <asp:CheckBox ID="chkSelectAll" runat="server" AutoPostBack="false" CssClass="checkbox-item-header" onclick="toggleCheckAll();" />
                                    </HeaderTemplate>
                                </tel:GridTemplateColumn>

A project in production works partially, on clients internets (phone, pc etc...) and works on our intranet.

A resource.axd generate an "ERR_CONNECTION_RESET"

difference with other ressource is long url auto generated :

<script src="/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RSM_TSM&amp;compress=1&amp;_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3afr-FR%3a10395c91-0c67-4b5f-be67-7f60b4835745%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2022.2.622.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3afr-FR%3adbbf043d-66df-4172-9982-e8bb59918fa4%3a16e4e7cd%3af7645509%3a88144a7a%3aed16cbdc%3a4877f69a%3a24ee1bba%3af46195d3%3a33715776%3ab2e06756%3a92fe8ea0%3afa31b949%3ac128760b%3a19620875%3a874f8ea2%3a490a9d4e%3ab7778d6c%3ae085fe68%3acda80b3%3a383e4ce8%3aa064d040%3a59462f1%3a7c926187%3aa51ee93e%3ac08e9f8a%3a58366029%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3afr-FR%3a10395c91-0c67-4b5f-be67-7f60b4835745%3a76254418" type="text/javascript"></script>

i can send you (in private domain base of url, before /Telerik..) to test.

how to reduce this url ? i think is size.

example of resource work in site :

/ScriptResource.axd?d=Acr7YYngYOcLwDrz111yAmfTtNXdiT2AVa5sxCuSkDiFfzEWUyUZNnYbx9cuBqADt0N7LO5fkpvKchmSSPLRCFpBkbQWzKznqT47xPMkxIKzMFwRcsSZO1XF28E6FKpA6I6deov79BgFLTYERhXvYwXJY1EGFuA2PN_d3WFfV_k1&t=14d69f50

 

Thanks for your help.

Hello -

We are using Telerik forms for our internal website. When I download one page with all its components, it is 73 files and 11.2 MB total size. Screen captures attached.

  • 10 axd files (4.4 MB)
  • 8 css files (328 KB)
  • 47 js files (2.7 MB)
  • 7 image files (84 KB)
  • 1 html file (3.7 MB)

Most of our site is made up of similar pages. Our site has an average 500 connections per second. During peak times, the website crawls, with 20-30 seconds to return one page for each user.

We are accessing only text, with about 200 KB of text returned for each request.

It looks like 99.3% of the size of our pages is Telerik related files (mostly axd and js).

What could we be doing wrong? What should we be doing differently to reduce the size or count of Telerik files returned to the client?

Thank you!
