Getting Started - Problems

[Adrian]

I've recently converted an ASP.NET 2.0 application to 3.5 and have been trying to add telerik.

vs2013 & Telerik asp.net ajax v2015.1.401.35

Recently converted an ASP.NET 2.0 web application to 3.5 and it runs fine.

I've used the telerik wizard to add the necessary bits to web.config.

Tried replacing the scriptmanager with RadScriptManager, but that errors with

JavaScript critical error at line 4, column 1 in http://localhost/iWebTest/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_ScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=3.5.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:eb198dbd-2212-44f6-bb15-882bde414f00:ea597d4b:b25378d2;Telerik.Web.UI:en-US:bfbc94e0-0f9b-4d52-9983-75ffc518eea7:16e4e7cd:f7645509:22a6274a\n\nSCRIPT1002: Syntax error 

so reverted to normal scriptmanager for now until that can be resolved.  

Created a new web form, added a radtextbox and a button then in click event in the code behind I tried to retrieve the textbox.text value..  it just returns the original value, not the changed one..

What the heck have I done wrong ?

Hello Adrian,

I advise that you follow this article: http://docs.telerik.com/devtools/aspnet-ajax/general-information/adding-the-telerik-controls-to-your-project.

It is important to first get MS AJAX working, i.e., have the needed WebResource handlers and references. You should firsts be able to use asp:UpdatePanels to initiate AJAX requests without script errors.

Afterwards, just add and reference our assemblies and copy the HTTP handlers we use from this article: http://docs.telerik.com/devtools/aspnet-ajax/general-information/web-config-settings-overview#mandatory-additions-to-the-webconfig.

Regards,

Marin Bratanov

I have a page that uses a standard update panel, which works just fine without errors.

I've added my web.config below (some lines removed for security)

The script manager is on the masterpage if that makes a difference?

Hello Adrian,

Remove the runtimeVersionv2.0 instruction from the Telerik handlers, because this causes IIS to skip them for .NET 3.5 and above.

Then add a location element for the handlers in use to allow access to them because authentication will block them otherwise. You can find an example here: http://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/general-troubleshooting#using-the-telerik-controls-with-radscriptmanager-on-your-login-page-throws-an-error.

Also, if this does not help, remove the AjaxControlToolkit from your project (make sure to also delete the assemblies from the bin, not just their references) and test again, because it is known to cause issues by modifying core MS AJAX scripts: http://www.telerik.com/forums/telerik-ui-for-asp-net-ajax-and-ajax-control-toolkit.

Ok, removed the runtimeversion2's and removed the ajax control toolkit, but it's still having problems.

Trying to use the RadScriptManager still brings up the same script error, and the textbox still contains the original value.

When looking at the properties for the textbox in debug mode, the text is set to the original, but the LastSetTextBoxValue is set to the new changed value.

Hi Adrian,

Have you tried adding location elements for the handlers? For example:

<location path="Telerik.Web.UI.WebResource.axd">
   <system.web>
     <authorization>
       <allow users="*"/>
     </authorization>
   </system.web>
 </location>

If you get script errors, it should be expected that the controls will not function properly. With authentication enabled, which will prevent access to the webresources handlers, the controls will not be able to download their scripts, so script errors are to be expected.

Another way you can avoid this is by enabling the scripts CDN: http://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/overview.

I already added the location element (as it was listed in that page you sent).

Can't use the CDN as the site is hosted by several customers on intranets with no access to the outside world.

As long as I use the standard script manager, I don't get any script errors, I only get the error I listed in the original post if I attempt to use the RadScriptManager

Hello,

Most likely, something goes wrong with the request RadScriptManager generates, because it combines the requests. If the ones from the asp:ScriptManager pass, you can use that.

On a side note - you can host a CDN on your own site for intranet use: http://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/custom-cdn-provider.

Finally found what we'd done wrong..   because we're using the standard scriptmanager, we have to add the following...

<asp:ScriptManager ID="ScriptManager1" runat="server">
    <Scripts>
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
    </Scripts>
</asp:ScriptManager>

The textboxes then have the correct values in them.
