If you are using asp:HiddenField controls (rendered as <input type="hidden" />) in your website and update their values with AJAX requests, you may observe some unexpected changes in the page layout in Internet Explorer (IE). It will seem that an empty line is inserted at each location where a HiddenField control resides. The behavior is observed only in IE and looks like a problem caused by the browser or the MS AJAX client-side framework. A quite easy workaround for this glitch is to wrap the HiddenField in a container with no height and reduced font size. Here is an...

I've made small demo how to export the grid content to a PDF file and show the result using RadWindow: When you click the "Export" button in RadToolBar the page will be reloaded and if the export is successful the application will open RadWindow to show the exported file. Initially the "Delete" button is disabled however once the window is shown the button will be enabled. To delete the exported file you can click the "Delete" button or just close the window.

Sounds like a book title, doesn’t it? No, I haven’t written a book on software testing. I’m on my way though, I just need fifteen or twenty years of Alan Page’s, Ken Johnston’s and BJ Rollisson’s experience and I’m ready to go with a new testing bible like the just announced “How We Test Software at Microsoft®”.

I’m sure the authors, who lead the Microsoft testing division of about 8000 testers, have a lot to share, but I was also happy to see the post ...

While working on a recent "real" project for Telerik, I used the RadTabStrip for ASP.NET AJAX to provide users with a list of content they could navigate. It was simple enough. A RadTabStrip with a few tabs, a RadMultiPage holding each tab's content, and content on each pageview that linked to new pages in the website. With very little effort, I had a rich, tabbed interface that worked completely cross browser. But then during beta testing, a tester reported a bug: if they navigated to a new page by clicking on content in the TabStrip, then clicked their browser's back button,...

I put out a survey about two weeks ago to ask you what controls you want to see in upcoming RadTips episodes. The 155 responses I received were spread fairly evenly, but it looks like the controls you are most interested in learning more about are the RadGrid, RadAjax, OpenAccessDataSource, & RadInputManager controls. Thanks to all who participated in the survey. Keep an eye out on my blog in the coming weeks as I start to deliver new RadTips that help you squeeze all the functionality out of these controls. If you have any specific features that you'd like to see me...
