Sort by result of IValueConverter

[Geoff Smith]

Is it possible to sort a GridViewDataColumn by the result of the converter rather than the object the column is bound to?

Hi Geoff Smith,

There are a couple of possible approaches here. Firstly, you can sort a column according to another one by setting in xaml the Property SortMemberPath. 
Another possible approach would be to add new property that returns the modified value. For example, if you have FirstName property that you would like to modify with a converter just create a ConvertedFirstName property that will return the converted value. After that bind the grid to the Converted* properties without using DataMemberBinding and IValueConverter.
Other approach would be to handle the Sorting event and implement custom logic. You can find a sample project illustrating that solution in this forum thread.

Kind regards,
