Exporting to Excel for hierarchical grid view i.e parent and child grid.
The Output Excel should be looks like drill down report which child report can be hidden/visible.

As a user I would like to have Unfocused state for selected GridViewCells when SelectionMode="Cell". 
Similar to the Unfocused state for selected GridViewRows (you can check this article as a reference: http://​www.telerik.com/help/wpf/gridview-selection-unfocused-state.html).

Enable multiple rows to be edited in a RadGridView at once.

We currently do this based on creating multiple row selection and editing the last selected cell and then applying the value (if valid to do so) across the selection.

Add a bindable property to RadGridView which would allow the selection to be manipulated in MVVM scenarios.

1) I created a 5 X 5 table.
2) Then I selected second column.
3) Then I applied Right Align to the selected column.
4)Then I Right clicked on the last row and selected Insert > Insert row below
5) It inserted the row with all cells left aligned.

The cells should adapt the alignment of the column they are in.

The last row is not fully visible when the gridview is scrolled to the bottom in case RowHeight is set to less than 20px. The less the row height the smaller the part of the last row which is visible. This is reproducible only in Office2013 theme. 

ArgumentOutOfRandeException in FlatLayoutStrategy.RealizeRows(). The exception occurs if RadGridView.GroupRenderMode="Flat"

StackOverflowException is thrown when perfoming sorting, filtering or grouping on GridView bound to DynamicObject

InvalidOperationException in FilteringViewModel.ClearFilters()

Scrolling performance is degraded when RowStyle/RowStyleSelector that sets Template property is explicitly applied

'Cell is already in the collection' exception is thrown when multiple cells are copied and pasted in a sorted column

ViewRow's background is not correctly colored when RadGridView is within RadBusyIndicator and it is busy. There is no problem if your are using GridViewLoadingIndicator.
