Sorting a datagrid fed from an arraylist of structs

[simon]

I have an arraylist of structs. They use a custom
table style to be displayed on my DataGrid. I
cannot figure out how to get the little triangles
to appear to allow for custom sorting.

The default sorting is done through a DataView which requires a DataTable. If you have just set your grid's DataSource to ArrayList, then there is no DataTable and hence no DataTable.

One solution would be to move your ArrayList into a DataTable, and bind that or a DataView based on it to your grid. Then the AllowSorting property of teh TableStyle would probably get you going on sorting.
