Our ASP.NET web forms project was updated from .NET 3.5 to .NET 4.5. This also meant we switched from Classic to Integrated pipeline mode for the App Pool. I began to see this error on pages that loaded the Telerik controls.

'~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use
the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

I made the following changes...

I removed <httpHandlers> and <httpModules> from <system.web>

I removed the reference to the .NET 2 Telerik.Web.Design and Telerik.Web.UI DLLs, and added a reference to the .NET 4 DLLs.

I added <add name="Telerik.Web.UI.WebResource" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" /> to the <system.webServer><handlers> section of web.config.

On my local workstation, this fixes the problem.

But, moving to our test web server, it still throws the same exception.

Test Server is confirmed running Windows Server 2008, IIS7, Integrated pipeline mode, .NET 4.5.

I've also tried leaving the <httpHandlers> in place, but that didn't work, either.

<httpHandlers>
            <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
            <add verb="*" path="Telerik.ReportViewer.axd" type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=4.1.10.714, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" />
</httpHandlers>

Hello,

I have a RadSplitter with 2 RadPanes

In Left pane i am loading TreeView List. In RightPane i am loading Radgrid with 10,000 rows.

Each page load, about 5-7 seconds RadSplitter shows small then expanding(Please see attachment) to full screen.

       var minWidth = 1000;
           var minHeight = 600;

           window.onresize = ResizeSplitter;

           function ResizeSplitter() {
               var splitter = $find("<%=RadSplitter1.ClientID %>");
               if (!splitter) return;
               var viewport = $telerik.getViewPortSize();
               var widthToSet = viewport.width > 1000 ? viewport.width : 1000;
               var heightToSet = viewport.height > 600 ? viewport.height : 600;
               splitter.set_width(widthToSet);
               splitter.set_height(heightToSet);
               var wrapper = $get("ParentDivElement");
           }


      </div>

We are using RadPivotGrid and was working fine until we change the sessionState to SQLServer. And now getting the error:

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

Hi,

I have a diagramming application which uses a RadToolBar to set attributes such as Bold, Italic and Underline - pretty standard stuff.

The RadToolBarButton's need to serve a dual purpose:

1. To set the attribute (e.g., Bold) of the selected object
2. To indicate the attribute setting for the selected object

I am using the check() method of the item to "highlight" it if the selected shape has that attribute set.

Unfortunately it seems that only 1 item can be checked at a time.

How do I go about checking/selecting/highlighting multiple toolbarbutton's?

Thanks in advance for any suggestion and code snippets.

Jim
