Wpf data grid custom column sorting
提问by Roman A. Taycher
How do I add a special sorting method to a particular column to allow different types of sorting(such as sorting 120.5.1.50 in between 120.5.1.12 and 120.5.1.110 instead of having 120.5.1.110 be the lowest value.
如何向特定列添加特殊排序方法以允许不同类型的排序（例如在 120.5.1.12 和 120.5.1.110 之间对 120.5.1.50 进行排序，而不是将 120.5.1.110 设为最低值。
Also how do I allow click header sorting of a custom type bound it a template column. Is this even possible?
另外，我如何允许自定义类型的单击标题排序将其绑定到模板列。这甚至可能吗？

You can implement IComparer and define your own comparing logic.
您可以实现 IComparer 并定义您自己的比较逻辑。
public class MyComparer : IComparer<Object>
{
public int Compare(Object stringA, Object stringB)
{
// Your logic here
}
}
After you can just use LINQ OrderBy method with your custom comparer.
在您可以将 LINQ OrderBy 方法与您的自定义比较器一起使用之后。
items = items.OrderBy(x => property, comparer).ToList();

If you want to maintain the custom sort order after clicking the column header, you can use an attached behaviour. I came up with this solution which seems to work well:
如果要在单击列标题后保持自定义排序顺序，可以使用附加行为。我想出了这个似乎运行良好的解决方案：
WPF DataGrid CustomSort for each Column
This is an MVVM solution - there are probably simpler ways of doing this if you want to delve into the world of code-behind.
这是一个 MVVM 解决方案 - 如果您想深入研究代码隐藏的世界，可能有更简单的方法可以做到这一点。
