RadEditor added to a Server Composite Control

[Jun]

I have successfully added a radeditor control inside a server compositecontrol:

protected override void CreateChildControls()
  {
    Controls.Clear();
    _txtBox = new TextBox();
    _txtBox.ID = "txtEdit";
   _edrBox = new RadEditor();
    _edrBox.ID = "edrEdit";

    _txtBox.TextChanged += new EventHandler(txtBox_TextChanged);
    _edrBox.ValueChanged += new EventHandler(edrBox_ValueChanged);
    this.Controls.Add(_txtBox);
    this.Controls.Add(_edrBox);
  }

But the problem is, when the server control is placed inside a formview and that formview is ajaxified by a radgrid (ie, in a master/detail relationship, clicking a row on the radgrid should refresh the details inside a formview), an Ajax javascript error shows up that a null reference is detected at the time of sys.load????

Attached is the javascript code (from microsoft ajax) showing the error where variable a is NULL.

Thanks for the response. The purpose of the server compositecontrol I created is to dynamically render a TextBox or RadEditor control on a page. The MicrosoftAjax.js is giving ajax error when only textbox is rendered by the composite control although the radeditor is added to the controls collection.

I think I am missing something to make this works when Ajax comes in. So I decided to create two composite controls, one for the textbox and one for the radeditor. So far, it is working good.

Thanks!
