XAML保證金錯誤

我試圖在Windows通用應用程序上生成一個動態表單，並且存在保證金問題。XAML保證金錯誤

我喜歡讓Radiobutton和Textbox在邊界0的左側。問題在於文本框不能停留在左邊，我有兩個控件，邊界爲0，不知何故，文本框正在推到屏幕的右側。

這是我運行應用程序後的結果。

在Windows 10

我的腳本文件名MainPage.xaml.cs中項目AppTestTrash

using System; 
using System.Collections.Generic; 
using System.IO; 
using System.Linq; 
using System.Runtime.InteropServices.WindowsRuntime;

namespace AppTestTrash 
{ 
    /// <summary> 
    /// An empty page that can be used on its own or navigated to within a Frame. 
    /// </summary> 
    public sealed partial class MainPage : Page 
    { 
     public MainPage() 
     { 
      this.InitializeComponent(); 
     } 

     private void Page_Loaded(object sender, RoutedEventArgs e) 
     { 
      //Add dynamic RadioButton 
      var dynamicRadiobtn = new RadioButton(); 
      dynamicRadiobtn.Name = "testme"; 
      dynamicRadiobtn.Height = 30; 
      dynamicRadiobtn.Width = 50; 
      dynamicRadiobtn.Margin = new Thickness(0, 100, 0, 0); 
      dynamicForm.Children.Add(dynamicRadiobtn); 

      //Add dynamic texbox 
      var dynamicTextbox = new TextBox(); 
      dynamicTextbox.Name = "testme2"; 
      dynamicTextbox.Height = 30; 
      dynamicTextbox.Width = 50; 
      dynamicTextbox.Margin = new Thickness(0, 120, 0, 0); 
      dynamicForm.Children.Add(dynamicTextbox); 
     } 
    } 
}

XAML文件MainPage.xaml中的Windows通用應用的輸出結果

要解決此問題，您可以將dynamicTextbox的HorizontalAlignment屬性設置爲Left像下面這樣。

//Add dynamic texbox 
var dynamicTextbox = new TextBox(); 
dynamicTextbox.Name = "testme2"; 
dynamicTextbox.Height = 30; 
dynamicTextbox.Width = 50; 
dynamicTextbox.HorizontalAlignment = HorizontalAlignment.Left; 
dynamicTextbox.Margin = new Thickness(0, 120, 0, 0); 
dynamicForm.Children.Add(dynamicTextbox);

的HorizontalAlignment的默認值是拉伸，所以你的文本框將在您的網格甚至左邊距爲0。欲瞭解更多信息的中心，請參閱備註HorizontalAlignment。
