    dear friends,

    I need a working sample that shows me if radeditor changed or not. I cannot simply use "if radeditor1.changed then savecontent" command. there are many possibilities and solutions of the forum. keydown event is first to control, copy paste, menu events etc. there are several solutions but nobody posted a fully functional example. I coluldn't manage combine all of them: can somebody help me please, I'm going crazy for 2 days. isnt there a simple way to learn if user changed the content of radeditor ? it cannot be so hard. I'm ready to accept that I'm an idiot but couldnt make it.

    best regards...

    (to admins: I posted code library section by mistake, sorry)

    Hi,

    You can use the following code:

    <telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="OnClientLoad">
    </telerik:RadEditor>
    <script type="text/javascript">
    var contentChanged = false;
    function OnClientLoad(editor) {
    editor.attachEventHandler("keydown", function(sender, e) {
    contentChanged = true;
    });
    }
    window.onbeforeunload = unloadMessage;
    function unloadMessage() {
    message = "Content has changed, save before exit?"
    if (contentChanged)
    return message;
    }
    </script>
    <asp:Button ID="Button1" Text="text" runat="server" />

    If the content is updated, the browser will ask the user whether she/he wants to proceed if the user tries to close the window or navigate to another page.

    Of course this is a base solution that should be enhanced by the developer working with the control.
