答

您好Salwa，

如果更改文本框文本意味着您想知道哪个标签页包含该文本框（活动标签页），据我所知。试试这个;

Hi Salwa,

If the Textbox text is changed means you want to know which tab page is contain that Textbox(Active Tab Page), For my understanding. try this;

string pare = textBox1.Parent.Controls.Owner.ToString(); //Here give your control instead of textBox1

我希望这会对你有所帮助。

谢谢

如果我理解你的问题，你问的是如何确定哪个标签是活跃的。如果这是你想要实现的，你只需要查看 TabControl 的 SelectedItem ，就像这样

If I understand your question properly, you are asking how do you work out which tab is active. If this is what you are trying to achieve, you simply need to look at the SelectedItem of the TabControl, like this

TabItem currentTab = MyTabControl.SelectedItam as TabItem;
