RadEditor looses contet

[Kalyani]

Hello,

I have a radwindow inside which I have a radeditor.  I load the radeditor with content from a database.  I have a preview button in the radwindow and when I click that it opens another radwindow.  When I close this radwindow it deletes the content in the radeditor.  It does not affect the rest of the controls in the radwindow.  It just affects the radeditor.  How do I fix this.

Here is my code with both the radwindow- 

<tlrk:RadWindow ID="Dialog1" runat="server" Width="900px" VisibleStatusbar="false" Behaviors="Close,Move">
  <ContentTemplate>
   <asp:UpdatePanel ID="Dialog1UpdatePanel" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
     <div class="DialogBase DialogShading1" style="width:100%">

      <asp:Label ID="lblSql" runat="server" Text =""/>
      <table class="center" style="width: 100%;">

        <td align="left" style="padding:10px"><strong>Help ID</strong> <br />
         <asp:TextBox ID="D0_txtHelpID" runat="server" Width="300px"  /></td>
        <td align="left"><strong>Title</strong> <br />
         <asp:TextBox ID="D0_txtTitle" runat="server" Width="500px"  /></td>

Hello,

I tried to reproduce the unwanted behavior on my end, but no avail.
I wasn't able to run your project due to various dependencies missing in it such as the database you are using. What I could advise you at this point is to to review the following demo showing a configuration similar to yours. If the provided information doesn't help you please try to isolate the issue in a simple, fully runnable project so that we will be able to reproduce and examine it locally.

Regards,
