The problem should be resolved with LIB version 2016.1.404.

MergedCellsStyle and MergedCellsStyleSelector properties will be available with Q2 2016.

UPDATE: The issue is reproduced with columns bound to other data types as well.

As of R1 2018 RadGridView supports pinning columns both on its left and right side. The new properties that control the right-side behavior are: RightFrozenColumnCount and RightFrozenColumnsSplitterVisibility.

Implement Excel-like horizontal locked scrolling. Clicking on the scrollbar should scroll into view the first column that is not visible at the moment, i.e. all visible columns should be moved out of the viewport.

Pasting in empty RadGridView is not possible.

Implicit row's style should be not cleared when the SelectStyle method of RowStyleSelector returns null.

When I have DistinctFilter set on the grid and I will search data from SearchPanel and then I will clear SearchPanel, Grid show me all data, not these from DistinctFilter, even if it's still set on the grid.

UI for WPF Q1 2016

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.

The issue can be solved with the help of the new added IsExpandableBinding property.

The fix is available in the R1 2018 SP2 Release.
