Currently, RadGridView's data engine relies on TypeDescriptor.GetProperties, when resolving the set of properties accessible through a certain type. Apparently, this API hides the properteis from the interface, as they are not accessible throught the concrete type.
When setting the VirtualItemCount on refreshing the data source, the scrollbar jumps to the top. If the VirtualItemCount is initially set, the behavior is not reproduced. The workaround is to use the scrolling mechanism of the control and scroll back to the desired item.
Currently, the default value of the property is true, so the presented of items in the hierarchy collection is not taken into account. This results in having visible hierarchy buttons for rows that do not have hierarchical subitems.

When applying VQCV with custom IEnumerable as a source to the ItemsSource of the grid and filters grid through filtering control, ExportToXlsx exports wrong items. Available in LIB version 2017.3.1127, it will be also available in the R1 2018 Release.
I have a RadGridView and bind its ItemsSource and its SelectedItem to properties of the ViewModel (DataContext). I use a ViewModel for the grid items with overridden Equals and GetHashCode. When the ViewModel is created, the property bound to ItemsSource is filled and the property bound to SelectedItem is set to an item that is equal to one of the items in the collection (but not reference equal). Problem: When the GridView is displayed, no item is selected. Note: I already reported this issue before: https://feedback.telerik.com/Project/143/Feedback/Details/227302-binding-itemssource-and-selecteditem-of-gridview-changes-selecteditem but now I have managed to modify the sample project so that the problem can be reproduced. The difference to the original sample project is that Equals and GetHashCode of the Club ViewModel are overridden and the selected item is not reference equal to the item in the collection.
When RadGridView is bound to a ListCollectionView and the SortDescriptions are set, columns with a SortMemberPath different from the DataMemberBinding don't display the sort indicator in the column header. In the attached example the "Status" and "ETA" columns are sorted. "Status" header does not display the indicator due to the SortMemberPath being different from the DataMemberBinding.
When the ItemsSource of the RadGridView is reset, disctinct values remain checked in the Filtering Popup.
For a workaround, check the attached project.
This happens only if there are many columns outside of the viewport (a scrollviewer is shown), with their TabStopMode property set to Skip.
In this case, the navigation needs some time in order to get to the next row and select the first available cell.
A possible workaround for this would be to implement a custom Keyboard Command Provider, and to replace the MoveNext command with a custom one, that moves the current cell, by setting the CurrentCellInfo property of RadGridView.
