更新选项卡控制来自另一个类的wpf [英] update tab control wpf from another class

问题描述

早上好



我有两节课

1级Window1：包含添加的标签控件

2级DesignerCanvas：必须在选项卡控件中添加文本

然后我在类DesignerCanvas中添加以下代码

good morning

I have two class
1-class Window1 : that contains the tab control added
2-class DesignerCanvas :must add a text in tab control
I then add the following code in the class DesignerCanvas

public  Window1 form;
      public  DesignerCanvas(Window1 form)
 {
     this.form = form;
 }
   public void SendBackward_Executed( object sender, ExecutedRoutedEventArgs e)
     {
         ((Window1)form).tabItem1.Content = "new text"  ;
     }

在类window1中我添加以下代码

In class window1 I add the following code

private DesignerCanvas test = new DesignerCanvas();

和方法public window1我添加：

and in the method public window1 I add:

public Window1()
       {
           InitializeComponent();
           test.form = this;
         //here is the error
           test.SendBackward_Executed(object sender , System.Windows.Input.ExecutedRoutedEventArgs e);

       }

有没有其他方法可以调用方法？

is there any other way to call the method??

推荐答案

即使前两行代码也不会编译，因为第一行中有一些代码垃圾。从代码中删除乱码，然后提出问题。但是从其他类中调用任何东西都没有任何麻烦：它只是访问修饰符的问题，更重要的是，正确设计代码。

Even the first two lines of code won''t compile, due to some code garbage in a very first line. Remove gibberish from the code and then ask a question. But there are no any hassles to call anything from "other class": it''s just the matter of access modifiers and, more importantly, proper design of the code.
