c# - WPF - 在文本框旁边动态添加按钮

Question

我正在动态创建标签、文本框和按钮。我需要 Button 与其右侧的文本框出现在同一行中。

这是我使用的代码:

    Label lbl = new Label()
    {
        Content = "Some Label",
        HorizontalAlignment = HorizontalAlignment.Left,
        VerticalAlignment = VerticalAlignment.Top,
        HorizontalContentAlignment = HorizontalAlignment.Center,
        VerticalContentAlignment = VerticalAlignment.Center,
        Height = 28,
    };

    TextBox tb = new TextBox()
    {
        Text = "Some Text",
        IsReadOnly = true,
    };

    Button btn = new Button()
    {
        Content = "Click Me",
        HorizontalAlignment = HorizontalAlignment.Left
        Margin = new Thickness(tb.ActualWidth),
    };

我将按钮边距分配给文本框的右侧，但它仍然出现在文本框下的下一行中。

我做错了什么？

您可以使用StackPanel 来解决您的问题:

StackPanel spMain = new StackPanel() { Orientation = Orientation.Vertical };

Label lbl = new Label()
  {
      Content = "Some Label",
      HorizontalAlignment = HorizontalAlignment.Left,
      VerticalAlignment = VerticalAlignment.Top,
      HorizontalContentAlignment = HorizontalAlignment.Center,
      VerticalContentAlignment = VerticalAlignment.Center,
      Height = 28,
  };

StackPanel spInner = new StackPanel() { Orientation = Orientation.Horizontal };

TextBox tb = new TextBox()
{
    Text = "Some Text",
    IsReadOnly = true,
};

Button btn = new Button()
{
    Content = "Click Me",
    HorizontalAlignment = HorizontalAlignment.Left,
    Margin = new Thickness(tb.ActualWidth),
};

spInner.Children.Add(tb);
spInner.Children.Add(btn);

spMain.Children.Add(lbl);
spMain.Children.Add(spInner);
