我正在构建一个WPF应用程序。 WPF对我来说很新，所以也许这是一个简单的问题：）
Catch是我构建DLL WPF库。现在我想将UserControl从这个dll导入我的应用程序几次（准确地说是6次）。
WPF DLL库它是带有点的Graph。到目前为止我导入DLL UserControl，但只显示没有点的ListBox（图形）。点可以与连接器（点之间）一起移动。
我的应用程序XAML：
<ScrollViewer>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<dr:UserControl1 Grid.Row="0" DataContext="{Binding UCData1, UpdateSourceTrigger=PropertyChanged}"/>
<dr:UserControl1 Grid.Row="1" DataContext="{Binding UCData2, UpdateSourceTrigger=PropertyChanged}"/>
<dr:UserControl1 Grid.Row="2" DataContext="{Binding UCData3, UpdateSourceTrigger=PropertyChanged}"/>
<dr:UserControl1 Grid.Row="3" DataContext="{Binding UCData4, UpdateSourceTrigger=PropertyChanged}"/>
<dr:UserControl1 Grid.Row="4" DataContext="{Binding UCData5, UpdateSourceTrigger=PropertyChanged}"/>
<dr:UserControl1 Grid.Row="5" DataContext="{Binding UCData6, UpdateSourceTrigger=PropertyChanged}"/>
</Grid>
</ScrollViewer>
我的C＃App： {
public MainWindow()
{
//InitializeComponent();
UserControl1 UCData1 = new UserControl1();
UserControl1 UCData2 = new UserControl1();
UserControl1 UCData3 = new UserControl1();
UserControl1 UCData4 = new UserControl1();
UserControl1 UCData5 = new UserControl1();
UserControl1 UCData6 = new UserControl1();
}
public object UCData1 { get; set; }
public object UCData2 { get; set; }
public object UCData3 { get; set; }
public object UCData4 { get; set; }
public object UCData5 { get; set; }
public object UCData6 { get; set; }
}
UserControl XAML DLL：

因此只显示“静态”事物。我的“节点”（点）和“连接器”（点之间的线）在哪里？如有任何问题，请询问。
