I'm running into a problem with the Q1 '08 build of the Editor specifically with the Image Manager.

The problem occurs when the Rad Editor is inside of an update panel and is initially not visible. Then if it is made visible via a postback and then the image manager is clicked, the Image Manager doesn't get rendered properly. Only bits and pieces of it show up and it is unusable. If I take it out of the update panel all works fine. Here is the basic test code:

Front-End:
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="scriptManager" EnablePartialRendering="true" runat="server" />
        <asp:UpdatePanel runat="server">
            <ContentTemplate>
                <asp:Button runat="server" OnClick="buttonclick" Text="Make Editor Visible" />
                <Telerik:RadEditor runat="server" ID="radEditor" Height="400px" EditModes="Design"
                    AutoResizeHeight="true" Skin="Web20">
                </Telerik:RadEditor>
            </ContentTemplate>
        </asp:UpdatePanel>
    </form>
</body>

Back End:

    protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
        {
            radEditor.Visible = false;
        }
    }

    protected void buttonclick(object sender, EventArgs e)
    {
        radEditor.Visible = true;
    }

What's the workaround for this?

Hi Erin,

Indeed, you are right - I was able to reproduce the problem.

I logged it in our ToDo list and we will do our best to fix as soon as possible.

In the meantime you can easily workaround the problem by adding the following code to the page's head - if the skins' path is different please change it:

    
            <link href="Skins/Web20/Window.Web20.css" rel="stylesheet" type="text/css" /> 
        
            <link href="Skins/Editor.css" rel="stylesheet" type="text/css" /> 
        
            <link href="Skins/Window.css" rel="stylesheet" type="text/css" />

Your points were updated.
