如何在Wpf TabControl中更改Tab项？ [英] How to change Tab Item in Wpf TabControl?

问题描述

嗨


我正在研究WPF MVVM项目。在视图上有Tab Control，它有4个Tab项。我想导航到按钮单击时的第一个选项卡项。我实现了一个SelectedIndex属性，如图所示



这里 [ ^ ]



我成功实施了它，但Tab Item在视图中没有变化。我还调试了CurrentIndex的值，更改了值。



在ViewModel中

  private   int  _CurrentIndex; 
 
  public   int  CurrentIndex 
 {
  get  { return  _CurrentIndex; } 
  set  
 {
 _CurrentIndex =  value ; 
  if （PropertyChanged！=  null ）
 {
 PropertyChanged（ 此， new  PropertyChangedEventArgs（  CURRENTINDEX））; 
} 
} 
} 

查看

 SelectedIndex =   {Binding Path = CurrentIndex，Mode = TwoWay}  

请帮助

解决方案

经过大量搜索后我找到了解决方案

我必须要写更多代码

 e.Handled =  true ; 

Hi
I am working on WPF MVVM project. On view there is Tab Control and it has 4 Tab Items. I want to navigate to the first Tab Item on button click. I implement a "SelectedIndex" property as shown

I successfully implemented it but Tab Item not changing in view. I also debug the value of "CurrentIndex", the value changed.

    get { return _CurrentIndex; }
    set
    {
        _CurrentIndex = value;
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs("CurrentIndex"));
        }
    }
