Refreshing datagrid result while connection is cut triggers SelectedTableColumns to reset implicitly in ConnectionReady > DBTreeFocusChanged > ParseSelectedTableStructure. Add an explicit Connection.Ping(true) before firing any query in DatagridBeforePaint, and merge code from ParseSelectedTableStructure into DBTreeFocusChanges. Fixes issue #2644.
