C# 我的参数创建不起作用usercontrol wpf }

请尝试下面的代码，它对我有用。为了简单起见，我刚刚包含了ControlWidth的代码

    <us:UCDataGrid x:Name="d" ControlWidth="1" ControlHeight="10" />

现在在xaml中为UserControl设置名称并访问它以设置绑定。暂时删除所有样式，并检查以确保没有在任何其他位置设置宽度和高度

public partial class UCDataGrid : UserControl
{
    public UCDataGrid()
    {
        InitializeComponent();
    }

    public static  DependencyProperty ControlWidthProperty =
    DependencyProperty.Register("ControlWidth", typeof(double), typeof(UCDataGrid),new UIPropertyMetadata());

    public double ControlWidth
    {
       get { return (double)GetValue(ControlWidthProperty); }
       set { SetValue(ControlWidthProperty, value);  }
    }
}

希望能有所帮助

您遇到了什么错误？你能分享一下UCDataGrid的代码吗？]@JayakrishnanGounder你能帮我吗当我在项目测试中调用datagrid时，他告诉我值无效哪个值？你能分享更多细节吗？当我在我的Xaml中调用ControlWidth并在这里给出值时，我发现我的值中有错误15是的，它可以工作，只是问题转换为int

    <us:UCDataGrid x:Name="d" ControlWidth="1" ControlHeight="10" />

public partial class UCDataGrid : UserControl
{
    public UCDataGrid()
    {
        InitializeComponent();
    }

    public static  DependencyProperty ControlWidthProperty =
    DependencyProperty.Register("ControlWidth", typeof(double), typeof(UCDataGrid),new UIPropertyMetadata());

    public double ControlWidth
    {
       get { return (double)GetValue(ControlWidthProperty); }
       set { SetValue(ControlWidthProperty, value);  }
    }
}
