Hi.
Since the latest servicepack (11.2.0.29), I haven't been able to only show filters for some columns.
When I generate my columns, some I set AllowFiltering = true on some, and others false. But the filtering button only gets visible, if I set AllowFiltering to true on the DataGrid instead of the column. And then it overrides the attribute on the columns.
This worked before the last update.
