    On closing IFRAME tags

    I was debugging some obscure problem the other day. For some reason the __doPostBack JavaScript function was not defined (or “undefined” in JavaScript terms ;) ). It wouldn’t be so suspicious if I was able to view the source of the page and see the declaration of __doPostBack routine. It turned out some iframe break the whole thing. Consider the following html (notice that the iframe is in minimized form): <div>I am before the iframe</div><iframe src="http://www.telerik.com" /><div>I am after the iframe</div> In that case the second div was not rendered at all.

    RadInput 2.0 and Date Parsing: Where Compiler Theory Meets User Needs
