[Daniel Qin]

Hello

i am using RadEditor(it's DNNRichTextEditor really) inside RadWindow. 
such like :

<telerik:RadWindow ID="WinAddNew" runat="server">
    <ContentTemplate>
         <cc1:DNNRichTextEditControl ID="txtContent" runat="server" Width="500" Height="300" />
    </ContentTemplate>
</telerik:RadWindow>

var editor;

        function pageLoad()  

        {  

            editor = $find("<%=txtContent.ClientID%>"); //get a reference to RadEditor client-side object   

        }

editor is null. 
even i am using $get. 
could you give me some advices?

Thank you.

Hello Daniel,

You can try the following code to get a reference to RadEditor

<script type="text/javascript">

    function pageLoad() {
        if (typeof ($telerik) != "undefined") {
            if ($telerik.radControls && Telerik.Web.UI.RadEditor) {
                for (var i = 0; i < $telerik.radControls.length; i++) {
                    var control = $telerik.radControls[i];
                    if (Telerik.Web.UI.RadEditor.isInstanceOfType(control)) {
                        //control is a radeditor object
                        control.set_html("<b>hello<b>");
                    }
                }
            }
        }
    }
</script>

The code should be run after our controls have been initialized (after the Sys.Application.Init event). The code I have pasted includes some extra checks to make sure it does not fail if there is no RadEditor on the page. To check the type of the control I use the isInstanceOfType method. See this article for more information: How-to create a javascript array of all particular RadControls on the page.

Another approach is to attach the OnClientLoad event to get a reference to RadEditor. See this KB article for more information: Executing custom code called on RadEditor's events.
