Pinned Rows
RadVirtualGrid rows can be pinned so that the rows appear anchored to the top or bottom of the grid. To pin a row you should use the SetRowPinPosition method where you just need to pass the row index and the desired pin position.
radVirtualGrid1.VirtualGridElement.SetRowPinPosition(2, PinnedRowPosition.Top);
radVirtualGrid1.VirtualGridElement.SetRowPinPosition(2, PinnedRowPosition.Top)
The result is that the row is pined bellow the filter row.
To unpin a row you just need to set its pin position to none.
radVirtualGrid1.VirtualGridElement.SetRowPinPosition(2, PinnedRowPosition.None);
radVirtualGrid1.VirtualGridElement.SetRowPinPosition(2, PinnedRowPosition.None)
