Did you try showing your window using the <a href="http://msdn.microsoft.com/en-us/library/system.windows.window.showdialog.aspx" rel="noreferrer">ShowDialog</a> method?

Don't forget to set the <a href="https://www.codeproject.com/tips/226984/make-a-wpf-dialog-window-as-application-modal" rel="noreferrer">Owner property</a> on the dialog window to the main window. This will avoid weird behavior when Alt+Tabbing, etc.

Given a Window object myWindow, myWindow.Show() will open it modelessly and myWindow.ShowDialog() will open it modally. However, even the latter doesn't block, from what I remember.

blocks|key|2060405|text|这些答案中有很多都是简单的，如果有人开始使用WPF，他们可能不知道所有的“细节”，因为这比仅仅告诉某人“使用.ShowDialog()!”要复杂得多。但这正是您想要使用的方法(而不是.Show())，目的是为了阻止底层窗口的使用，并防止代码在模式窗口关闭之前继续执行。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2060406|首先，你需要2个WPF窗口。(其中一个将呼叫另一个。)|2060407|在第一个窗口中，假设它被称为MainWindow.xaml，在其代码隐藏中将是：|2060408|public+partial+class+MainWindow+:+Window
{
++++public+MainWindow()
++++{
++++++++InitializeComponent();

}|code-block|syntax|javascript|2060409|然后将您的按钮添加到您的XAML：|2060410|<Button+Name="btnOpenModal"+Click="btnOpenModal_Click"+Content="Open+Modal"+/>|2060411|右键单击Click例程，选择"Go+to+definition“。它将在MainWindow.xaml.cs中为您创建它：|2060412|private+void+btnOpenModal_Click(object+sender,+RoutedEventArgs+e)
{
}|2060413|在该函数中，您必须使用其页面类指定另一个页面。假设您将另一个页面命名为"ModalWindow"，这将成为它页面类，也是您实例化(调用)它的方式：|2060414|private+void+btnOpenModal_Click(object+sender,+RoutedEventArgs+e)
{
++++ModalWindow+modalWindow+=+new+ModalWindow();
++++modalWindow.ShowDialog();
}|2060415|假设您有一个需要在模式对话框上设置的值。在ModalWindow+XAML中创建一个文本框和一个按钮：|2060416|<StackPanel+Orientation="Horizontal">
++++<TextBox+Name="txtSomeBox"+/>
++++<Button+Name="btnSaveData"+Click="btnSaveData_Click"+Content="Save"+/>+
</StackPanel>|2060417|然后，再次创建一个事件处理程序(另一个Click事件)，并使用它将TextBox值保存到ModalWindow上的公共静态变量中，然后调用this.Close()。|2060418|public+partial+class+ModalWindow+:+Window

A lot of these answers are simplistic, and if someone is beginning WPF, they may not know all of the "ins-and-outs", as it is more complicated than just telling someone "Use <code>.ShowDialog()</code>!". But that is the method (not <code>.Show()</code>) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.

First, you need 2 WPF windows. (One will be calling the other.)

From the first window, let's say that was called MainWindow.xaml, in its code-behind will be:

<pre><code>public partial class MainWindow : Window
{
 public MainWindow()
 {
 InitializeComponent();
 }
}
</code></pre>

Then add your button to your XAML:

<pre><code>&lt;Button Name="btnOpenModal" Click="btnOpenModal_Click" Content="Open Modal" /&gt;
</code></pre>

And right-click the <code>Click</code> routine, select "Go to definition". It will create it for you in MainWindow.xaml.cs:

<pre><code>private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
}
</code></pre>

Within that function, you have to specify the other page using its page class. Say you named that other page "ModalWindow", so that becomes its page class and is how you would instantiate (call) it:

<pre><code>private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
 ModalWindow modalWindow = new ModalWindow();
 modalWindow.ShowDialog();
}
</code></pre>

Say you have a value you need set on your modal dialog. Create a textbox and a button in the <code>ModalWindow</code> XAML:

<pre><code>&lt;StackPanel Orientation="Horizontal"&gt;
 &lt;TextBox Name="txtSomeBox" /&gt;
 &lt;Button Name="btnSaveData" Click="btnSaveData_Click" Content="Save" /&gt; 
&lt;/StackPanel&gt;
</code></pre>

Then create an event handler (another <code>Click</code> event) again and use it to save the textbox value to a public static variable on <code>ModalWindow</code> and call <code>this.Close()</code>. 

<pre><code>public partial class ModalWindow : Window
{
 public static string myValue = String.Empty; 
 public ModalWindow()
 {
 InitializeComponent();
 }

 private void btnSaveData_Click(object sender, RoutedEventArgs e)
 {
 myValue = txtSomeBox.Text;
 this.Close();
 }
}
</code></pre>

Then, after your <code>.ShowDialog()</code> statement, you can grab that value and use it:

<pre><code>private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
 ModalWindow modalWindow = new ModalWindow();
 modalWindow.ShowDialog();

 string valueFromModalTextBox = ModalWindow.myValue;
}
</code></pre>

If I have a Xaml Window, how does one open it as a child window, and then have the parent window wait for the child to close before the parent window continues executing?
