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.
Also how do I allow click header sorting of a custom type bound it a template column. Is this even possible?
You can implement IComparer and define your own comparing logic.
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.
items = items.OrderBy(x => property, comparer).ToList();
Refer to this link.
Edit TO override the default sorting behaviour of a WPF Datagrid, refer to the answer in this link.
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:
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.
