c# - 如何使 GridViewColumn 只读/禁用？

Question

GridViewColumn我在我的 xaml 代码中有对 a 的引用，RuntimeColumn但我无法禁用它或以编程方式将其设置为只读。我需要在运行时执行此操作而无需数据绑定。

我试过了：

this.RuntimeColumn.IsEnabled = false;
this.RuntimeColumn.ReadOnly = false;

有任何想法吗？

您必须使用 Loaded Event 设置一个 EventSetter，并在您的代码后面放置以下内容

private void GridViewColumnHeader_Loaded(object sender, RoutedEventArgs e)
    {            
        GridViewColumnHeader columnHeader = sender as GridViewColumnHeader;
        Border HeaderBorder = columnHeader.Template.FindName("HeaderBorder", columnHeader) as Border;
        if (HeaderBorder != null)
        {
            HeaderBorder.Background = HeaderBorder.Background;
        }
        Border HeaderHoverBorder = columnHeader.Template.FindName("HeaderHoverBorder", columnHeader) as Border;
        if (HeaderHoverBorder != null)
        {
            HeaderHoverBorder.BorderBrush = HeaderHoverBorder.BorderBrush;
        }
        Rectangle UpperHighlight = columnHeader.Template.FindName("UpperHighlight", columnHeader) as Rectangle;
        if (UpperHighlight != null)
        {
            UpperHighlight.Visibility = UpperHighlight.Visibility;
        }
        Thumb PART_HeaderGripper = columnHeader.Template.FindName("PART_HeaderGripper", columnHeader) as Thumb;            
        if (PART_HeaderGripper != null)
        {
            PART_HeaderGripper.Background = PART_HeaderGripper.Background;
            PART_HeaderGripper.Cursor = System.Windows.Input.Cursors.Arrow; // override the size curser
        }
    }
