Sometimes it can be valuable to display hierarchy data in a grid.  It can allow users to quickly drill down into the data at the click of a button.  Below you will see a sample database with just three tables. Notice that this is very elementary example, but it works well to demonstrate how easy it is to leverage hierarchy within the RadGridView control.  I am using LINQToSQL to pull the data from the database.  Below you will see the classes created after I did a drag and drop of the tables using Server Explorer in Visual Studio 2008. Now I can...

I've already blogged about the new RadInputManager control in the Beta of Q3 2008 for RadControls ASP.NET AJAX. One of the other very useful features that you can now take advantage of in the RadInputManager is its RegExpTextBox setting. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information. You can use it to constrain input, apply formatting rules, and check lengths. If you capture input by using TextBox controls, you can use the RegExpTextBoxSetting settings to validate that input - for example to restrict the range of valid characters, to strip...

Our insatiable commitment to deliver more than expected in every aspect of our products resulted in me being curious, if we are as flexible as we think and whether one can always achieve his goal be it out of the box or with custom solution using our API and other controls if necessary. Hmmm what could that custom solution be – how about a custom Toolbar for our web ReportViewer. For those of you, who are unfamiliar with our Web ReportViewer , here is a short description – it is designed to render Telerik Reports within ASP.NET projects and it has a toolbar that...

The ImageEditor dialog in RadEditor has been around for about half a year, providing much wanted common image editing capabilities to the editor's end users.      This dialog in fact is the front-end of a basic image editing engine that has been built into the Telerik.Web.UI.dll. Some time ago our colleague Todd Anglin suggested that we make the API public so it can be used independent of the editor. Sounded like a good idea - and the coming Q3 2008 will allow you to take advantage of it :)  And since the functionality is already available in the already released RadControls Futures (which acts...

Last week the ASP.NET team released a Beta of Q3 2008 for RadControls ASP.NET AJAX.  You can download it from http://www.telerik.com/community/forums/thread/b311D-bgmcha.aspx  , and run examples built with it on the online samples page here http://demos.telerik.com/aspnet-ajax-beta/Controls/Examples/Default/DefaultCS.aspx.  The Q3 2008 will be shipped with a new server control - RadInputManager. The RadInputManager offers an easy and intuitive way to extend a standard ASP.NET TextBox. Sometimes web apps will contain, for whatever reason, a large number of Input controls that can significantly impact the page performance. A great solution in these cases is to use RadInputManager. The big benefit with this control is that it...
