AJAX Error on the ComboBox with a inner TreeView

Hi,

I'm using the telerik Rad controls for ASP .NET AJAX version 2009_3_1103

I have two RadComboBox with a RadTreeView each one.
When I check a node in the first TreeView (in the first ComboBox) the second treeview is rebinding with a new information.
The all is ajaxifing with a RadAJAXManager.

The thing is that this work fine when I check one and two times but on the third time the following error is occurring!

The error is:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Best regards.

Hi,

I am using the WebBlue as the theme. When the list is long, in IE8 overflow is not working, so the items get transparent, but the default skin is working in IE8.

These are the configuration i have used in the config file,

    <appSettings>
       <add key="Telerik.Skin" value="WebBlue"/>
       <add key="Telerik.EnableEmbeddedSkins" value="false"/>
   </appSettings
        <pages theme="WebBlue" enableViewStateMac="true" maintainScrollPositionOnPostBack="false" viewStateEncryptionMode="Auto">
           <controls>
               <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
               <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
               <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
           </controls>

RadControls In MOSS !!!!

Hello,

I want to use RadMenu and RadGrid controls in moss2007, both of these controls will be in hierarchy. In each row of RadGrid I have to load actions from the database on ItemDataBound event of grid.
I've done the configurations provided at the "Incorporating RadControls in MOSS sites" page.
When I load the menuitems statically, It works but when I load it from database, the page doesn't show up and some error occurs.

Second thing, I want to apply the radcontrols' skin on both RadGrid and RadMenu, how to do that?
I copied the "RadControls/Grid" and "RadControls/Menu" folders to the Images folder of the website and changed the properties of the controls respectively but some IOException is thrown by MOSS.

Please help me asap.

Regards,

Talha Majeed.

Issue with RadWindow and focus on controls

Hello.

We have an ASP page showing a list of tasks. When clicking on one of the tasks, we show the task in a RadWindow using the radopen function. The RadWindow then shows a new asp page. This works fine, but if we in the page load event of the asp page shown in the RadWindow, set focus to an asp textbox, the scrollbar in the web browser moves to the top. This cause the RadWindow to scroll out of visibility for the user when user has scrolled down in the task list to open a task.

Is this a bug in the RadWindow control?

We use the latest version - 2009 Q3 SP2.

Regards, Rolf
