無法在窗口上設置自定義位置

Question

我正在使用http://wpfmdi.codeplex.com/庫來處理我的WPF應用程序中的MDI。

我有一個Canvas其中包含一個子容器，所有的小窗口將被放置在這裏。我想要在x = 500，y = 500的位置打開窗戶。然而，用我現在的代碼，窗口總是在畫布的左上角打開。

下面我粘貼了我的XAML和在畫布上打開一個新窗口的代碼。

<Canvas Name="cnvsMain" Background="LightGray" AllowDrop="True" Drop="cnvsMain_Drop"> 
    <mdi:MdiContainer Name="mainContainer" Background="LightGray"> 
    </mdi:MdiContainer> 
</Canvas> 


      TableWindow tableWindow = new TableWindow(tableName); 
      listTableWindows.Add(tableWindow); 

      mainContainer.Children.Add(new MdiChild() 
      { 
       MaximizeBox = false, 
       MinimizeBox = false, 
       Resizable = true, 
       ShowIcon = false, 
       Title = "X", 
       Position = new Point(500,500), 
       Content = tableWindow.Content as UIElement //Opens new instance of my window class 
      }); 

任何想法？我也嘗試從我的窗口課程中設置位置，但無濟於事。

只是spitballing在這裏，因爲我還沒有與特定的圖書館工作，但不是

mainContainer.Children.Add(new MdiChild() 
{ 
    MaximizeBox = false, 
    MinimizeBox = false, 
    Resizable = true, 
    ShowIcon = false, 
    Title = "X", 
    Position = new Point(500,500), 
    Content = tableWindow.Content as UIElement //Opens new instance of my window class 
}); 

你試過

var child = new MdiChild 
{ 
    MaximizeBox = false, 
    MinimizeBox = false, 
    Resizable = true, 
    ShowIcon = false, 
    Title = "X", 
    Position = new Point(0, 0), 
    Content = tableWindow.Content as UIElement //Opens new instance of my window class 
}; 

mainContainer.Children.Add(child); 
child.Position = new Point(500, 500); 
//  or 
//child.Margin = new Thickness(500, 500, 0, 0);
