WPF选项卡控件:如何获得当前选中的选项卡?

In my tab SelectionChanged event (is this the correct event, I can't find a tab changed event?), how do I access the new tab?

在我的选项卡选择更改事件(这是正确的事件吗，我找不到选项卡更改事件吗?)中，我如何访问新选项卡?

Also from outside this event in normal code, how do I access the currently selected tab?

同样，在普通代码中，从这个事件之外，我如何访问当前选中的选项卡?

  TabControl.SelectionChanged += new System.Windows.Controls.SelectionChangedEventHandler(TabControl_SelectionChanged);

  void TabControl_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
  {
      //How so access my currently selected tab???
  }

3 个解决方案

#1

TabControl.SelectedItem is the selected tab.

TabControl。SelectedItem是选中的选项卡。

cast it to a TabItem to get the properties.

将其转换为TabItem以获取属性。

What I mostly do is bind it to a viewmodel.

我主要做的是将它绑定到一个viewmodel。

#2

you can use the TabControl.SelectedItem property, it will get you the selected TabItem

您可以使用TabControl。SelectedItem属性，它将获取所选的选项卡项

Sample shown below

示例如下所示

TabItem ti = Tabs1.SelectedItem as TabItem;
MessageBox.Show("This is " + ti.Header + " tab");

#3

TabControl.SelectedIndex gets you the currently selected tab index in version 3.0 and later of the .NET Framework.

TabControl。SelectedIndex在3.0版本和。net框架的稍后版本中为您提供当前选定的选项卡索引。
