WPF TabControl Change selected tab
提问by Kent Boogaart
Hi I have two questions.
你好，我有两个问题。
- How do I programatically change the selected tab in a WPF Tab control from one tab to another.
- How would I get a reference to this "other tab" in which I want to set the selected tab?
- 如何以编程方式将 WPF Tab 控件中选定的选项卡从一个选项卡更改为另一个选项卡。
- 我如何获得对要在其中设置所选选项卡的“其他选项卡”的引用？
回答by Kent Boogaart
- Use
SelectedIndexorSelectedItemor by changing the value of the property to which those properties are bound - If you're using
SelectedIndex, you don't need a reference to the tab. If you're usingSelectedItem, you need a reference to the data itemfor that tab - not the tab itself. If you've bound one of those properties to another property, you change that property rather than changing the property on theTabControl.
- 使用
SelectedIndex或SelectedItem或 通过更改绑定这些属性的属性的值 - 如果您正在使用
SelectedIndex，则不需要对选项卡的引用。如果您使用的是SelectedItem，则需要对该选项卡的数据项的引用- 而不是选项卡本身。如果您已将这些属性之一绑定到另一个属性，则更改该属性而不是更改TabControl.
