Hello Howard,

I have modified the sample I sent you before, so now all the logic is moved in the code behind.

Hope this helps you.

Great info -- getting me further.     I have a follow up question

First I am doing everyting programatically/in code.   XAML just for the layouts. 

I see now that I need to sort by two columns  one with a custom sort.

something like this

fieldLayout.SortedFields.Add(

new FieldSortDescription("ColumnName1", e.SortDescription.Direction, false

));

fieldLayout.SortedFields.Add(

new FieldSortDescription("NCustomSort", e.SortDescription.Direction, false

)); 

Also I have a custom class called NCustomSort and it is of IComparer

How do link this sort routine to the FieldSortDescription?

Thanks

Hello Howard,

Thank you for your post. I have been looking into it and I created a sample project for you with the functionality you want. Basically I added an UnboundField bound to the whole DataItem, which is Hidden and when you click a Button a custom sort is executed over the XamDataGrid.

Hope this helps you.
