使用DataGridColumnHeader C＃绑定DataGrid组头。

Question

我对C＃和WPF还是陌生的，我一直在研究解决问题的方法已经有几个小时了。

因此，问题是： 我有这个DataGrid，它具有我已经完成的分组功能。 如果用户单击列标题，它将按代表该列的属性对项目进行分组。 我设法使组标题采用以下格式： “ {Group Name} {Items Count}”

我想使其成为这样： “ {Column Header}：{Group Name} {Items Count}”

问题是我没有做到这一点。

我有DataGrid的XAML，我真的希望我能在这里找到一个解决方案，并且我不会违反任何法律或重复任何事情，在此先感谢：
