WPF选项卡控件拖放：将选项卡置于前面的行为
问题描述：
我想用tab控件实现拖放操作，即将项目拖到标签条上将其放在最前面。
哪一种是最有效且最不干扰的方式？
I would like to implement drag 'n drop with a tabcontrol in a way that dragging an item to tag strip brings it to front. Which is the most efficient and non obtrusive way?
谢谢
答
private void TabControl_DragEnter(object sender, DragEventArgs e)
{
TabItem item = e.Source as TabItem;
TabControl tabControl = sender as TabControl;
if (item != null && tabControl != null)
{
if (tabControl.SelectedItem != item)
tabControl.SelectedItem = item;
}
}
