如何在C＃/ WPF（.NET 3.5）中将自定义UserControl显示为对话框？

Answer 1

private void Button1_Click(object sender, EventArgs e)
{
    Window window = new Window 
    {
        Title = "My User Control Dialog",
        Content = new MyUserControl()
    };

    window.ShowDialog();
}

Answer 2

Window window = new Window
            {
                Title = "My User Control Dialog",
                Content = new OpenDialog(),
                SizeToContent = SizeToContent.WidthAndHeight,
                ResizeMode = ResizeMode.NoResize
            };
            window.ShowDialog();

对我来说就像魔术一样。它可以作为模态对话框吗？

Ans：ShowDialog它自己将其作为模态对话.. ...

据我所知你不能这样做。如果你想在对话框中显示它，那就完全没问题，只需创建一个只包含UserControl的新窗口，并在创建该窗口的实例后调用ShowDialog（）。

修改 UserControl类不包含ShowDialog方法，因此您尝试做的事实上是不可能的。

然而，这是：

private void Button_Click(object sender, RoutedEventArgs e){ new ContainerWindow().ShowDialog(); }

Answer 4

namespace System.Window.Form
{
    public static class Ext
    {
        public static DialogResult ShowDialog(this UserControl @this, string title)
        {
            Window wind = new Window() { Title = title, Content = @this };
            return wind.ShowDialog();
        }
    }
}

使用它可能就像UserControlInstance.ShowDialog（）一样简单。更好的自定义实现是扩展Window类并使用设计器和代码自定义它以获得任何功能。

Answer 5

我知道这适用于.net 3.5，但这是适用于.net 2.0的解决方案

  MyUserControl myUserControl= new MyUserControl();

  Form window = new Form
  {
    Text = "My User Control",
    TopLevel = true,
    FormBorderStyle = FormBorderStyle.Fixed3D, //Disables user resizing
    MaximizeBox = false,
    MinimizeBox = false,
    ClientSize = myUserControl.Size //size the form to fit the content
  };

  window.Controls.Add(myUserControl);
  myUserControl.Anchor = AnchorStyles.Top | AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right;
  window.ShowDialog();

Answer 6

您还可以使用MaterialDesignThemes.Wpf（可从NuGet下载，.NET 4.5+）。然后，您可以简单地执行以下操作：

{
    var view = new YourUserControl();
    var result = await DialogHost.Show(view, "RootDialog", ClosingEventHandler);
}

private void ClosingEventHandler(object sender, DialogClosingEventArgs eventArgs)
{ }  //Handle Closing here

如果“sixlettervariables”的答案被修改为如此，则可以正常工作

private void button1_Click ( object sender, RoutedEventArgs e )                  
{
    Window window = new Window
    {
        Title = "My User Control Dialog",
        Content = new UserControl ( ),
        Height = 200,  // just added to have a smaller control (Window)
        Width = 240
    };

    window.ShowDialog ( );
}
