Allow setting the group header rows height with a property similar to the RowHeight property of RadGridView. For example, a new GroupHeaderRowHeight property can be introduced. The new property should be included also in the UI virtualization calculations. 

Add a textbox which allow search and filter functionality for the distinct values in the FilteringControl of RadGridView.

In the meantime, you can check the attached project that shows one way to achieve this.

The new properties will be available with Q2 2016. 

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.

Currently, the aggregate results in the GroupHeaderRow are not aligned according to the columns whose value they summarize. We can introduce such functionality which will require modifying the control template of the GroupHeaderRow.

Completed in R3 2017.

InvalidOperationException in FilteringViewModel.ClearFilters()

Add keyboard support for the filtering, grouping and sorting features of RadGridView. The keyboard action should start the corresponding action for the column of the current cell. Keyboard actions should be included also for navigation in the UI of the FilteringControl after it gets opened.

Available in LIB version 2016.3.1121, it will be also available in the 2017 R1 Release.

MergedCellsStyle and MergedCellsStyleSelector properties will be available with Q2 2016.

radGridView has a feature to provides a suggest and append feature.  Currently, there is the ability for the end user to inadvertently close this window.  Please provide the opportunity via a property to disable the ability to close the search window.  (currently, I am hooking the SearchPanelVisibilityChanged event, and forcing showSearchPanel = true at all times.

Scheduled for: 
The exposed property (SearchPanelCloseButtonVisibility) will be available with LIB (version 2018.3.1210) published on Monday, 10-th December, 2018. 

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).

Currently, RadGridView scrolls three rows when using the mouse wheel. There should be an API that allows developers to change this setting.

А new virtualization mechanism for ColumnGroups will be introduced with Q2 2015. A property EnableColumnGroupsVirtualization is exposed with default value True for enabled virtualization. Setting it to False will enable the old logic.
