WPF获取活动/聚焦选项卡 [英] WPF Get Active/Focused Tab

问题描述

Heya，



我正在使用带有多重TabElements的TabControl（在运行时动态添加）。



如何找出它们中的哪一个是焦点/当前有效，所以我可以检索它的索引？



谢谢

推荐答案

用户用

.SelectedItem

public void Test_focus(Object o, EventArgs e)
        {
            if (stageTabCtrl.SelectedItem == EventBrowser)
            {
                MsgBox.Show("EventBrowser");
            }
            else if (stageTabCtrl.SelectedItem == Live_View)
            {
                MsgBox.Show("Live_View");
            }
}

<tabcontrol borderthickness="1,0,1,1" name="stageTabCtrl" gotfocus="Test_focus"></tabcontrol>
