Question

我有这个片段：

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:external="clr-namespace:ToggleSwitch;assembly=ToggleSwitch"
        xmlns:modern="clr-namespace:Tools.Views.New_Project"
        xmlns:Controls="clr-namespace:Assergs.Windows.Controls;assembly=Assergs.Windows"
        x:Class="Tools.FirstInterface"
        Title="Nouveau projet" Height="Auto" Width="Auto"
    WindowStyle="None"
        >

    <Grid  >
        <DockPanel>
        <Grid   DockPanel.Dock="Bottom" Height="38" VerticalAlignment="Bottom" Background="LightGray"  >
        <Button Content="Annuler"   Background="White" HorizontalAlignment="Right" Width="80" Height="22" VerticalAlignment="Bottom" Margin="0,0,0,8" BorderBrush="CadetBlue"  BorderThickness="2" FontWeight="Bold" FontFamily="Times New Roman"  />
        <Button Content="Suivant >>"  Background="#FFF9F7F7" Margin="0,0,94,8" HorizontalAlignment="Right" Width="81" Height="22" VerticalAlignment="Bottom" RenderTransformOrigin="0.5,0" BorderBrush="CadetBlue"  BorderThickness="2" FontFamily="Times New Roman" FontWeight="Bold" Click="Button_Click_4"/>
        <Button Content="&lt;&lt; Précédent" Background="White" Margin="0,0,180,8" HorizontalAlignment="Right" Width="82" Height="22" VerticalAlignment="Bottom" BorderBrush="CadetBlue"  BorderThickness="2" FontFamily="Times New Roman" FontWeight="Bold"/>

      </Grid>
            <UserControl x:Name="container"></UserControl>
        </DockPanel>
    </Grid>
</Window>

问题是网格中的按钮不可点击!!!即使我在后面的代码中添加此方法：

private void Button_Click_4(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("hello world!!");
        }

当我点击按钮时没有任何反应。

修改我认为问题来自用户控制

<UserControl x:Class="Tools.Views.New_Project.TypeOfProject"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

为什么？
我该如何解决？
