ListView模板列之间没有间隙
我有一个使用ListView控件的简单应用程序，它已编辑模板以禁用任何选择。基本上它就像Grid一样，但它可以使用ItemsSource属性获取项目并具有列。我已经使用了来自MSDN的ListView控件的模板，并删除了所有选择等但仍然 一些利润仍在那里，我无法得到如何删除它们。
xaml如下：

代码隐藏是：
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
listView.ItemsSource = new List<dynamic> {
new {X=5,Y=5},
new {X=5,Y=5},
new {X=5,Y=5},
new {X=5,Y=5},new {X=5,Y=5},
new {X=5,Y=5},
new {X=5,Y=5},
new {X=5,Y=5}};
}
}
因此集合很简单，而且ListView只为每个项目显示多个X和多个Y字符串。
这就是应用程序窗口与列之间的间隙看起来的样子。
如何消除差距？
1 个答案:
答案 0 :(得分：1)
正如您在此source code中所看到的，这是GridViewColumn的默认保证金。
private static readonly Thickness _defalutCellMargin = new Thickness(6, 0, 6, 0);
此值在CreateCell(GridViewColumn column)的私有GridViewRowPresenter方法中使用，无法覆盖。您唯一能做的就是在单元格模板中设置反向边距。
Margin="-6,0"
