    Optimize your ASP.NET data entry validation

    With RadControls for ASP.NET AJAX Q3 2008 we introduced our brand new component called RadInputManager. You can find more info about this unique control on following articles: Introducing the RadInputManager control for ASP.NET AJAX Using Regular Expression TextBox Using RadInputManager RadInputManager First Look I've made small demo to check how the input manager will perform compared to standard validation approach in ASP.NET and here is the result: - RadInputManager: 200 standard TextBox controls with skins (hover, focus, empty, negative, enabled/disabled, read-only & invalid styles), in-place validation and formatting and many more.   - Standard Validation controls: Huge render size & JavaScript, no in-place validation (only on...

    Taming Ajaxified asp:HiddenField Controls in Internet Explorer

    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.

    Don'ts in Software Testing

    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®”. Check out Alan’s and BJ’s posts on the subject here and here. 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 ...
