    Enabling Asp.net development on Vista 64

    Well as I figured it out it was not a complicated thing, but there are some specifics of course: Installing IIS By default IIS7 is included in the distribution (I use the Enterprise edition of Windows Vista), but is not installed by default. To do so open ControlPanel > Programs and Features. On the right side of the window click the "Turn Windows features on or off" link and a dialog will open: Installing required features You can select and check the Internet Information Services feature. By default not everything required gets selected. You have to check also the Internet Information Services>World Wide Web Services>Security>...

    RadMessageBox for WinForms

    Hello folks. I am sure all of us are enjoying with Telerik’s good looking and reach theming mechanism for WinForms. But in every application there is a need for user interaction and very often it uses some type of question or message to guide the user what he is supposed to do.   I am sure that you have used the default WinForms MessageBox class and its Show method  The standard appearance of this message box, however, does not fit nicely in the slick design of an application built with RadControls for WinForms, and I know how boring it is to implement your own...

    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...
