控制WPF在Winforms内不刷新

本文关键字：刷新 Winforms WPF 控制 | 更新日期: 2023-09-27 18:02:40

我很抱歉我的英语。

我有一个WINFORMS项目，其中有一个WPF用户控件。

WPF正确地显示了我，但是当我更新WPF中的一些控件时，没有更新我这样的控件。(文本框，标签，图像等)

在Winforms中留下一个简单的WPF示例，当您单击该按钮时，应该在文本框中显示"Hello World"。但我没有工作。

Form1.cs 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace IntegracionWPF
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
    {
        // Create the ElementHost control for hosting the
        // WPF UserControl.
        ElementHost host = new ElementHost();
        host.Dock = DockStyle.Fill;
        // Create the WPF UserControl.
        UserControl1 userControl1 = new UserControl1();
        userControl1.setText("Hola Mundo");
        // Assign the WPF UserControl to the ElementHost control's
        // Child property.
        host.Child = userControl1;
        // Add the ElementHost control to the form's
        // collection of child controls.
        this.Controls.Add(host);
    }
    }
}

userControl1.xaml.cs 

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace IntegracionWPF
{
    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
        }
        public void setText(string text)
        {
            textBox1.Text = text;
        }
    }
}

希望您正在寻找元素宿主。这对你有帮助。修改按钮，点击form1 

    private void button1_Click(object sender, EventArgs e)
    {
        // Create the ElementHost control for hosting the
        // WPF UserControl.
        ElementHost host = new ElementHost();
        host.Dock = DockStyle.Fill;
        // Create the WPF UserControl.
        UserControl1 userControl1 = new UserControl1();
        userControl1.setText("Hola Mundo");
        // Assign the WPF UserControl to the ElementHost control's
        // Child property.
        host.Child = userControl1;
        // Add the ElementHost control to the form's
        // collection of child controls.
        this.Controls.Add(host);
    }
