inherited treeview throws exception when using LoadXmlString

[wg]

Hi,

When I use my own TreeView which is inherited from RadTreeView, it doesn't work like the base class and throw exception. 
My version is 2013.1.403.40

First I create the new TreeView, very simple.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Telerik.Web.UI;

namespace TreeViewTest
{
    public class XTreeView:RadTreeView
    {
    }
}

Then I drag it to a aspx page. on the code behind. I write code like this.

                string xmlStr = @"<Tree>
  <Node Text='Desktop' Expanded='True' ToolTip='Desktop' ImageUrl='~/TreeView/Img/Vista/desktop.png'>
    <Node Text='Administrator' ImageUrl='~/TreeView/Img/Vista/folder-personal.png' Expanded='True'>
      <Node Text='AppData' ImageUrl='~/TreeView/Img/Vista/folder.png'>
        <Node Text='Microsoft'  ImageUrl='~/TreeView/Img/Vista/folder.png'/>
      </Node>
      <Node Text='Contacts' ImageUrl='~/TreeView/Img/Vista/folder-contacts.png' />
      <Node Text='Downloads'  ImageUrl='~/TreeView/Img/Vista/folder-open.png'/>
      <Node Text='Documents' ImageUrl='~/TreeView/Img/Vista/folder-documents.png' Selected='True' />
      <Node Text='Favorites' ImageUrl='~/TreeView/Img/Vista/folder-favorites.png' >
        <Node Text='Links'  ImageUrl='~/TreeView/Img/Vista/folder.png'/>
      </Node>
      <Node Text='Music' ImageUrl='~/TreeView/Img/Vista/folder-music.png' />
      <Node Text='Pictures' ImageUrl='~/TreeView/Img/Vista/folder-pictures.png' />
      <Node Text='Saved Games' ImageUrl='~/TreeView/Img/Vista/folder-open.png'  />
      <Node Text='Searches' ImageUrl='~/TreeView/Img/Vista/searches.png'  >
        <Node Text='History'  ImageUrl='~/TreeView/Img/Vista/folder.png'/>
      </Node>
      <Node Text='Videos' ImageUrl='~/TreeView/Img/Vista/folder-videos.png' />
    </Node>
    <Node Text='Computer' ToolTip='My Computer'  ImageUrl='~/TreeView/Img/Vista/computer.png' Expanded='True' >
      <Node Text='WebServer (\\10.0.0.80) (W:)' ImageUrl='~/TreeView/Img/Vista/network-drive.png' />
      <Node Text='Local Disk (C:)' ImageUrl='~/TreeView/Img/Vista/system-drive.png' Expanded='True' >
        <Node Text='inetpub'  ImageUrl='~/TreeView/Img/Vista/folder.png' Expanded='True'>
          <Node Text='AdminScripts'  ImageUrl='~/TreeView/Img/Vista/folder.png'></Node>
        </Node>
      </Node>
    </Node>
  </Node>
</Tree>";
                XTreeView1.LoadXmlString(xmlStr);

Just xml string and LoadXmlString. It gives me error.  The same code works well with base RadTreeView.

Could you please take a look at it?

Thank you very much.

Hello Bill,

I would like to clarify that some of the attributes are not inherited directly and need to be declared explicitly. Please add the XML serialization attribute [XmlRoot("Tree")]  as shown in the code snippet below:
//code behind

[XmlRoot("Tree")]
public class XTreeView : RadTreeView
{
}
