Respect IVirtualizedItemProvider for items of RadGridView . 

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.
