“We were able to create a grid that supports hierarchical data by leveraging the ListBox control in the framework”
“We were able to implement the grid without writing a single line of code for doing rendering, hit testing, scrolling or measuring text. All of this functionality, and more, we got for free”
“In addition, the styling infrastructure of the framework allowed us to expose an incredible level of customization support for users of the control with minimal effort”
