C# WPF-动态添加文本框旁边的按钮

我正在动态创建标签、文本框和按钮。我需要按钮出现在同一行作为文本框的权利

这是我正在使用的代码：

    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),
    };

我正在将按钮边距指定给TextBox的右侧，但它仍然显示在TextBox下的下一行中

我在这里做错了什么？

这取决于您放置控件的页面内容是什么，是网格还是其他什么

为什么不创建一个stackpanel，根据需要适当地包含您的项目。

您可以使用stackpanel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);

为什么不将所有创建的控件放置在StackPanel中，并将其方向设置为水平。这样，它们将始终挨在一起

var stPanel = new StackPanel { Orientation = Orientation.Horizontal };
var button = new Button() { ... }
stPanel.Children.Add(button);
//And so on

我认为如果您使用Button实例中的Content方法会更好

 private byte _count;
    internal void FillbtnSubCat(Grid grid)
    {
        var myDefinition = new ColumnDefinition();
        var myButton = new Button();
        var myBlock = new TextBlock()
        {
            TextAlignment = TextAlignment.Center,
            TextWrapping = TextWrapping.Wrap,
            Text = "Some Text",
            Margin = new Thickness(5, 10, 5, 10)
        };

        Grid.SetColumn(myButton, _count);
        myButton.Margin = new Thickness(5, 10, 5, 25);
        myButton.MinWidth = 30;

        myButton.Content = myBlock;

        myDefinition.Width = new GridLength(68);
        grid.ColumnDefinitions.Add(myDefinition);
        grid.Children.Add(myButton);
        _count++;
    }
