如何使用C＃链接两个Wpf Windows [英] How Do I Link Two Wpf Windows Using C#

问题描述

我有两个WPF窗口，即 MainWindow 和 Window1 。在 MainWindow 我有一个文本框（ textbox1 ）和一个按钮，在 Window1 中我有一个文本框（ textbox2 ） 。



我想要完成的是当我点击按钮时， textbox1 中输入的内容现在显示在 textbox2中。



我相信我的xaml对于两个窗口都是正确的，我在我的中添加了private void button_click_1 ..... MainWindow.cs 的。但是当我尝试输入动作时：



textbox2.Text = textbox1.Text;



它无法识别 textbox2





我是WPF的新手c＃所以任何帮助将不胜感激。谢谢

I have two WPF windows, that is MainWindow and Window1. In MainWindow i have a textbox(textbox1) and a button, in Window1 i have a textbox(textbox2).

What i am trying to accomplish is that when i click the button, whatever is typed in textbox1 is now displayed in textbox2.

my xaml i believe is correct for both windows and i have added the "private void button_click_1....." in my MainWindow.cs. however when ever i try to type the action:

textbox2.Text = textbox1.Text;

it does not recognize textbox2


I am fairly new to WPF and c# so any assistance would be appreciated. Thanks

推荐答案

请看我对这个问题的评论以及我过去的答案：在另一个窗口文本框中重复wpf Datagrid数据 [ ^ ]。



请学习一些OOP基础知识，否则你会在不理解基础知识的情况下学习太高级的东西。最终，它可能会带来很多挫折。

Please see my comment to the question and my past answer: Repeat wpf Datagrid data in another window text boxes[^].

Please learn some OOP basics, otherwise you are going to too advanced stuff without understanding of fundamentals. Eventually, it may end up with a lot of frustration.

首先，为两个窗口文件创建两个viewModel。



定义一个属性，它将从每个ViewModel中的文本框获取和设置值

。



为打开窗口创建NavigationService.cs类：

让NavigationService.cs



现在将以下代码放在该类文件中。

First, Create two viewModels for both window files.

Define one property which will get and set values from textbox
in each ViewModel.

Create NavigationService.cs class for opening window:
Let NavigationService.cs

Now put following code in that class file.

public void ShowWindow1Screen(Window1ViewModel window1ViewModel)
       {
           Window1= new Window1();
           Window1.DataContext = window1ViewModel)
           Window1.Owner = nicknameView;
           Window1.ShowDialog();
       }

然后。





创建NavigationService实例.cs类MainWindowViewModel文件。

然后

then.


Create instance of NavigationService.cs class MainWindowViewModel file.
then

Window1ViewModel window1ViewModel = new Vindow1ViewModel();
window1ViewModel.Name = MainWindowTextValue;
NavigationService navigationService = new NavigationService();
navigationService.ShowWindow1Screen(window1ViewModel);
