Hello Abdulaziz,

If I understand correctly, you need the primary key from the row that parents the table where you drop a row. If so, you can try the following in RowDrop:

GridDataItem parentItem = e.DestDataItem.OwnerTableView.ParentItem;
string key = parentItem.GetDataKeyValue("KeyName").ToString();

All the best,
