RadGridView's FooterRow is still part of the visual tree, even though its Visibility is set Collapsed. 

Cell gets out of the edit mode when new items are added in the collection. The same scenario works correctly if alternation is applied by RowStyleSelector. 

The problem should be resolved with LIB version 2016.1.404.

If I change Column.IsVisibility to FALSE, the column group headers are disappear and not restored.

The problem should be resolved with LIB version 2016.1.404.

The new properties will be available with Q2 2016. 

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

There are cells exported for the group rows, but they are empty. If you define ColumnGroupDescriptors instead GroupDescriptors, then the exported data is the correct one.

Fixed for GroupRenderMode="Flat".

When Unicode characters are copy pasted from grids via CTRL + C and then pasted into Excel or Word (for example) as a HTML table, it seems like for every Unicode character a certain amount of bytes / characters are cut off from the end result.

Workaround:

Define an implicit Style targeting GridViewRow UI element under Window.Resources or RadGridView.Resources section.

Pasting in empty RadGridView is not possible.
