InvalidOperationException is thrown from the synchronizing of the pinnedItems state when the ItemsSource collection of RadGridView is changed by asynchronous operations.

Changing ItemsSource of the GridViewComboBoxColumn runtime leads to empty cells in that column.

The exception is fixed. To evaluate the IsReadOnlyBinding of the column, we do not use the built-in binding mechanism but a custom one. This custom binding mechanism is designed to use as a source only the default one which is the current item of the ItemsSource of RadGridView. This is the reason that the scenario where the default source of the binding is changed is not supported by design.

A possible workaround is to predefine the CellTemplate of the column as well.

Provide an option to group a column which is based on an enum by the enum value, but display the DescriptionAttribute or DisplayNameAttribute if existing.
So many times you have sort/group a column by its value like 1,2,3 but display the Description like "Delivery", "Ready", "Pickup". Of course I could add a column to my class which presents the DescriptionAttribute, but then grouping/sorting is wrong: "Delivery", "Pickup", "Ready". It would by much easier if there is an option like "UseDescription". There is something similar with Teleriks "EnumDataSource" which IS using the Description or DisplayName so it should not be that hard to implement the same logic for RadGridView.

Provide option to enable changing the column display index when dragging group cell into the header row.
