在后面的代码中更改Canvas.Left属性？ [英] Change Canvas.Left property in code behind?

问题描述

我的XAML中有一个矩形，想要更改其 Canvas.Left 属性的代码如下：

I have a rectangle in my XAML and want to change its Canvas.Left property in code behind:

<UserControl x:Class="Second90.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Width="400" Height="300" KeyDown="txt_KeyDown">
    <Canvas>
        <Rectangle 
            Name="theObject" 
            Canvas.Top="20" 
            Canvas.Left="20" 
            Width="10" 
            Height="10" 
            Fill="Gray"/>
    </Canvas>
</UserControl>

但这不起作用：

private void txt_KeyDown(object sender, KeyEventArgs e)
{
    theObject.Canvas.Left = 50;
}

有人知道这样做的语法吗？

Does anyone know what the syntax is to do this?

推荐答案

Canvas.SetLeft(theObject, 50)
