Hi,
I would try to use the "Javascript to execute on asynchronous postback" about "Read Only Display Field" but there's a lack of documentation, have u understand this use, can u give me some examples please ?
Grid fields are very user-friendly, as you can show multiple columns. Settings the width is done via CSS casses, that you need to add to 'customer.css'. You can set the width per column (in pixels). I will post some examples below.
