[Solved] Enable Save button when content in RadEditor has changed (client-side)

[Scott]

I'm trying to achieve the following:

On a page I have a series of radeditor controls that will load the last saved data. I have a Save button that I do not want to be enabled until the user begins typing or makes a change of some kind into any of the radeditors. I tried the advice on http://www.telerik.com/help/aspnet-ajax/editor-attacheventhandler.html to attach a handler to the "onkeydown" event but it does not seem to be firing at all. "Onclick" works, but not "onkeydown".

Here is what I have in a demo page:

<div>
    <telerik:RadScriptManager ID="ScriptManager1" runat="server" >
    </telerik:RadScriptManager>

   <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">

            function OnClientLoad(editor, args) {
                var element = document.all ? editor.get_document().body : editor.get_document();
                $telerik.addExternalHandler(element, "onkeypress", function (e) {
                    $('#<%=btnSave.ClientID %>').text = "Save";
                    $('#<%=btnSave.ClientID %>').disabled = false;
                });
            }

        </script>
    </telerik:RadCodeBlock>

    <telerik:RadEditor runat="server" ID="reText" Height="400px" Width="100%" EditModes="Design" Skin="WebBlue"
        DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.axd" StripFormattingOnPaste="MSWordRemoveAll"
        StripFormattingOptions="MSWordRemoveAll" AjaxUrl="~/Telerik.Web.UI.SpellCheckHandler.axd" EnableResize="false" OnClientLoad="OnClientLoad" >
    </telerik:RadEditor>

    <telerik:RadButton ID="btnSave" runat="server" Text="Current" Enabled="false" />
</div>

Any help to achieve my scenario is appreciated!

Thanks,

Typo in the function, but still the same result

​

function OnClientLoad(editor, args) {

    var element = document.all ? editor.get_document().body : editor.get_document();

    $telerik.addExternalHandler(element, "onkeydown", function (e) {

        $('#<%=btnSave.ClientID %>').text = "Save";

        $('#<%=btnSave.ClientID %>').disabled = false;

    });

}

Hi scott,

Please do the following modification in your JavaScript which works fine at my end.

JavaScript:

function OnClientLoad(editor, args) {
    editor.attachEventHandler("onkeypress", function (e) {
        $find("<%=btnSave.ClientID%>").set_text("Save");
        $find("<%=btnSave.ClientID%>").set_enabled(true);
    });
}

Thanks,
Shinu.
