Currently all of the MoveCurrentTo methods rely on the internal logic of MoveCurrentToPositionCore and users cannot override it through inheritance.

Respect IVirtualizedItemProvider for items of RadGridView . 

Currently, within the LoadItems() method the items are being iterated directly, thus a second query to the database is triggered.  A separate list for this operation should be created.

You can find our online documentation on a detailed information on the currently supported grouping:

Workaround: reused the cell element like this:
CreateCellElement(Telerik.Windows.Controls.GridView.GridViewCell cell, object dataItem)
{
    var button = cell.Content as Button;
    . . .
 
    return button;
}

It is difficult to track whether the newly added items are pasted or not crated by insert.
