    We've created a custom widget for SF5.4 with title and content fields. The title field is a normal textbox so that's easy, but the content section needs to be a RadEditor. It's displaying, but the dialog window isn't resizing correctly. See attached screenshot.

    Any ideas why this would happen?

    I would hazard a guess that the RadEditor is doing some stuff in pageLoad or post pageload perhaps and the dialog doesn't know it's new size?

    Try setting a timeout of like 1-2 seconds, then run this
    function resizeDesigner() {
        if (dialogBase != null){
            dialogBase.resizeToContent(); //Refresh

    If that works, you know that's the culprit and maybe can hook into the OnClientLoad load event of the radeditor to call the above.

    Thanks for the response Steve,

    Where would I put this code? I've tried putting it directly in the widget control, but raises a client side exception saying: Uncaught ReferenceError: dialogBase is not defined.

    This happens even if I take out the dialogBase.resizeToContent(); expression within the if statement block.

    Am I supposed to get a reference to the dialog window first somehow?

    You could use css to re-size the dialog for example using  width 100% !important in a style section of the template:
    <style type="text/css">

    Note that you need to use the id/class of the dialog.

    Furthermore, you could take a look at the following blog post:
