wpf拖拽

简单拖拽的实现是，实现源控件的MouseDown事件，和目标控件Drop事件。调用DragDrop.DoDragDrop()以启动拖放操作，DragDrop.DoDragDrop()函数接受三个参数：dragSource、data以及allowedEffects。特别需要注意的 是dragSource参数。该参数标示了拖拽操作的消息源，也决定了所有的消息源事件由谁发出。参数data则用来包装Drag&Drop所操 作的数据。一般情况下，其都是一个DataObject类型的实例。该实例内部应包装拖拽所实际操作的数据。最后，allowedEffects可以用来 指定拖拽操作的效果。调用该函数的片断可以如下所示：

DragDrop.DoDragDrop(mListBox, dataObject, DragDropEffects.Copy);

例子1：从groupBox中拖动TextBlock控件到右侧Listbox中
