All DragVisualProviders for the RadListBox, as described in http://www.telerik.com/help/silverlight/radlistbox-features-dragdrop.html, show as a bare minimum a horizontal line that clearly shows where the drop within the list will occur.

Unfortunately the RadGridView does not even have that out of the box for its DragVisualProviders, so dragging elements within a RadGridView provides no indication at all to where the drop will happen! This seems like a very basic feature the RadGridView should have to support dragging/dropping within it (which also seems like a very common functionality).

The NullReferenceException is observed when the GridView is Grouped and rebound in the CellEditedEnded event handler.

The problem should be resolved with lib version 2016.1.125.

You can not select different filtering options through keyboard navigation. The only possible way to select a filtering operator from the list with available filtering operators is to click on it.

Resolved with lib version 2014.2.721.

GridViewDataColumn.IsVisible binding is broken in a custom scenario. The problem is reproducible only in child GridView.

Add an option to clear all filters at once to the column filters.

Rows get duplicated when SortDescriptors are applied and items are added to SelectedItems collection by a behaviour.

Application hangs on start up if GroupRenderMode is set to Nested, there is a column with Width Star and a group descriptor applied.

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. 

When RadGridView is grouped by a column with ShowColumnWhenGrouped property set to False and GroupDescriptors are cleared, the column does not get visible. 

These issues should be resolved with lib version 2014.3.1110.

Resolved with lib version 2014.2.0825.
