    RadTreeView's TriState Mode in Deep

    November 19, 2010 Share
    Many of you have probably used Telerik's TreeView or going to do so in the future. One of its many features is the TriStateMode. In this blog post I'm going to explain how TriStateMode mode is designed to work and propagate the values up and down the tree. When in TriStateMode (IsTriStateMode=”True”) checking/unchecking an item makes the TreeView propagate the value. The value propagation actually checks/unchecks all items’ children and updates the chain of parents with appropriate value (checked, unchecked or undetermined). CheckState vs. IsChecked The TreeView exposes two properties used to manipulate items' check state - CheckState (of type ToggleState) and IsChecked...

    Want to see the (bright) Future of Silverlight?

    November 16, 2010 Share
    The latest release of Silverlight - ver.4 was released earlier this year. For me this was the first Silverlight release that was stable and mature enough so that I could recommend to anyone building business applications to use it broadly. Now, six months later, we can see that the Silverlight adoption is very high and that there are a lot of great tools built with it. Regardless of all the recent comments and mostly speculations about the future of Silverlight I believe that this will be the primary MS platform for building applications for Windows and Mac in years to come. At MIX this year, the Silverlight platform was also introduced to...

    Expression Descriptors in Q3 2010 for WPF & Silverlight

    November 11, 2010 Share
    Another four months have gone by and another awesome release of RadControls has arrived! One of the exciting new features in this release are the so-called 'Expression Descriptors'. Previously, whenever our clients wanted to filter data but needed even more control than our good old FilterDescriptor could provide, they had to subclass it and override some of its methods. Even though that approach works, it is tedious and cumbersome. And, as much as LINQ Expressions rock, having to manually generate expression trees by hand... yuck! The new FilterDescriptor<T> allows you to directly plug a predicate that determines which items are filtered. You...

    Bookvar goes open source

    It is a great pleasure for me to share an exciting news with you. As of today we are opening the source code of Bookvar mind mapping tool. You can find the source on Codeplex right next to other open source initiatives of ours, like Telerik MVC Extensions and CAB Enabling Kit for WinForms. A few caveats about the source code There are a few things that you need to know about the source code: Most of the code was written when we were quite new to WPF and we were pioneering all those concepts. Looking back at that time I realize there are things that...
