jQuery UI Dialog issue

jQuery UI Dialog issue

I have faced this many time with different controls. What happens is, when control like DevExpress RichEdit, SpreadSheet, or Telerik Editor is being used inside a jQuery UI Dialogue, and when we open the dialog on a button click then these controls inside the dialog won't be loaded properly (I mean loaded without any CSS). This also happens with many jQuery widgets that I use inside jQuery UI Dialogue. To sort this out, what I do is, put the same control outside jQuery UI Dialogue with display:none, so CSS get loaded properly first and that solves issue with controls which is inside jQuery UI Dialogue.
Question, is that a proper method to resolve this issue?
