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.

CheckState vs. IsChecked The TreeView exposes two properties used to manipulate items' check state - CheckState (of type ToggleState) and IsChecked...

They also asked everyone to play musical chairs. Nicely done, very Agile of...

The new Test Scheduling and Remote Execution feature we added with the Q3 release is a powerful addition to our Automated Testing Tools offering. The feature pushes WebUI Test Studio into multi-machine execution and enables customers to leverage the physical & virtualized environments to schedule and execute test runs. You can also collect results across this distributed environment into a centralized repository. This feature makes WebUI more appealing to large enterprises with larger test labs and machine pools. With this blog post I’m sharing all the basics of the feature in the form of FAQ. In addition I will also ...

One of the major goals for our AJAX RadEditor control is to provide an accessible content creation experience. For us, this task is divided into two major categories - having an accessible editor UI and helping the end user produce accessible content. With the Q3 2010 release, we made improvements to both and I want to share the results with you.  The first major improvement is the new AccessibleRadEditor control. It is a stripped down version of the full featured RadEditor and has a simpler toolbar to allow easy navigation using only the keyboard. All tools have assigned shortcuts and even the...
