Hi

I have the following problem:

I initialize XamDataGrid layout in code-behind in FieldLayoutInitializing event handler. Some of the fields are defined as Hidden right from the start, but can be Unhidden by the user in run-time. The problem is when I make those field visible again, by setting:

field.Visibility =

Visibility.Visible

they don't appear in the group-by area.

How can I fix it, so the previously hidden fields, when become visible will also appear in the group-by area?

Thanks
