I have two radtreeviews on a page and i would like to drag and drop nodes between the two. I have the drag working fine the destination treeview is adding nodes correctly, but the source treeview is DELETING the dragged node. I am trying to CLONE the source node and reinsert it, to prevent the deletion, but when i simply call:

sourceNode.TreeView.Nodes.Insert(sourceNode.Index, sourceNode.Clone());

I receive the following error. How is it possible that the sourceNode does not match the sourceNode in a CLONE()??? We are using the version v 2008.2.1001.35 of the RadAjax controls.

System.Reflection.TargetException was unhandled
  Message="Object does not match target type."
  Source="System"
  StackTrace:
       at System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object component, Object value)
       at Telerik.Web.UI.RadTreeNode.Clone()

I am adding dynamic tabs within a tab, not sure what I am doing wrong. I get a javascript error. UserControl gets loaded dynamically into a Tab and withing that tab I am trying to add more tabs. It worked when I used NavigateUrl in the content page Tabs.

Could someone please check my code and advise.
Thanks
p.s. I accidentally posted in the asp.net forum.

Hi:

I installed the Telerek controls and launched the Live Demo - got this - It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.    C:\Program Files\Telerik\RadControls for ASPNET AJAX Q3 2008\Live Demos\backup\web.config

Can you help me pls.

In ie6 the Title bar does not appear for the RadWindow. I'm just using a customised version of the RadWindow Css. Is it a problem with my code?

Hello, I am having a strange issue.

First I should note that I am working with the Telerik control suite for the first time with a new company. I am working with the ASP.NET Ajax controls and am running an application with the .NET 2.0 framework.

The specific problem I am running into is that adding a control to a web form causes a blank page to render.

What I am doing is this; creating a page which will use multiple Telerik controls.

First I successfully designed a page which uses the RadSplitter control and this page renders correctly.

The next step was to add a RadPanelBar to one of the Splitter's panes, however when I did this, none of the web page markup renders, all I get is a blank page.

To begin troubleshooting, I removed all other code/controls on the page and simply added the Script Manager and the example code for a basic RadPanelSplitter as given in the "First Look" example on the main site. This is the only code now in the page besides the basic page tags requisite for any ASPX form.

When this page is run I get, again, nothing but a blank page. In fact none of the web form markup is rendering, the markup the "blank" page contains (using the browser's view source) is this:


Besides there being almost nothing but basic tags, it almost appears that the form element is just completely missing from the markup (which is necessary), but also there is code in the Head tag besides the one meta tag shown which is not rendering.

This is very strange behavior, and I'm not getting any errors at all... Perhaps since I have not worked with the Telerik controls before I have made a simple mistake, but any help would be greatly appreciated.

Thanks!

I have two websites. Both have a scheduler that read all appointments from an appointments.xml file.
Website 1 insert appoitments into the appointments.xml and the scheduler on that website 1 refreshes and shows all appointments correctly. But, website 2 has a lag. All new appointments inserted by website 1 are not shown. 

How could I get website 2 to immediately pick up the changes?
I hope my question is clear. Thanks in advance for any tips.

Can you help me in it with a little code example? Please.....!!!

I want all this working more optimize and more on client side, whatever things are possible.

I have a strange problem with a sample test web application.

I put a single radtextbox on the aspx page along with a standard asp.net button. What I do is, I set the value to the text property of the radtextbox in Page_Load method and after I change the value of the radtextbox and click the button to go to the server side, the text value is still the same.

Same thing applies to all radinput controls, radeditor, etc.

Am I doing something wrong?

Here are the contents of my sample application:
ASPX:

C#:

When I change the value aaabbbccc to something else and click the button, the value of RadTextBox1.Text is still aaabbbccc!
