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... -

How To: Export grid to PDF file and show the result using the window
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 ...December 08, 2008 4 min read -

Easily persist RadTabStrip Selected Tab using client-side API
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,... -

The Survey Results are In!
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...December 05, 2008 1 min read -

Custom format strings and DateTime support in RadChart for WPF
One of the most common requests we got after the Q3 2008 release was to improve our label customization. Well I believe many of you will be pleasantly surprised to learn that we will most certainly deliver on those expectations for the Q3 SP1 release and then some! This news is really twofold. The first part is the support for custom format strings in our axis and series items labels. What this means is that with the SP1 release of RadChart for WPF you will be able to apply all .NET supported standard numeric format strings. The easiest way to enable... -

Auto-complete ComboBox with WCF Service and RadControls for Silverlight
Sometimes we need to load very large amount of items in a ComboBox and let the user select one of them. Usually in those cases the ComboBox allows typing in order to auto-select the items, that contain the text in the control. Such scenarios are possible with RadComboBox for Silverlight and now I will show you a simple application, that demonstrates what I think is a better practice for the implementation. We want to put all words from the English dictionary of RadSpell for ASP.NET in a RadComboBox for Silverlight and allow the user to select one of them, that will... -
