默认情况下,Silverlight自带的ListBox控件如果内部有多个TextBox,用户无法用键盘上的Tab键,在ListBox内部的TextBox之间切换。但Teterik RadControls 中的telerik:ListBox却很好的解决了这个问题,只要把telerik:ListBox的IsTabStop设置成false,同时把TabNavigation设置成Local即可(而SL自带的ListBox就算设置了这二个属性,Tab键需要按二次才能切换焦点)

意外惊喜:之前写过一篇博文,讲述了 Silverlight自带的ListBox,无法应用Blend中的MouseDragElementBehavior(即:应用该行为仍然无法拖动ListBox),但是telerik:ListBox发现居然可以(本例中,用鼠标按住telerik:ListBox中的任一文本框的边框,即可拖动整个ListBox)--商业控件就是给力!
