onbeforepaste event handler does not seem to work

[John]

onbeforepaste does not seem to work when attatched (client side) at the OnClientLoad_RadEditor event.  If I change 'onbeforepaste' to 'onclick' it works. My goal is to eventually prevent when certain conditions exist.

function OnBeforePaste_Editor(e){
    debugger;
    alert("paste attempted");
    e.returnValue=false; /* disable pasting to test*/
}
function OnClientLoad_RadEditor(editor, args) {
    editor.attachEventHandler("onbeforepaste", OnBeforePaste_Editor);
    ...
}

Thanks in advance,

Hi John,

It is not possible to assign handlers to the onbeforepaste / onafterpaste DOM events because they are handled by the editor itself to perform various manipulations to the pasted content.

In order to prevent pasting of content into the RadEditor's content area you can use its OnClientPasteHtml event, e.g.:

<telerik:RadEditor ID="RadEditor1" runat="server" OnClientPasteHtml="OnClientPasteHtml">
</telerik:RadEditor>

<script type="text/javascript">
    function OnClientPasteHtml(editor, args)
    {
        alert("paste attempted");
        args.set_cancel(true); //cancel further execution
    }
</script>

All the best,
