Hi I am using DataBoundGrid. I create dataset which has two tables QueryThread and Queries. ds.Tables.Add(queryThreadTable); ds.Tables.Add(queryTable); ds.Relations.Add("QueryThreadQuery",queryThreadTable.Columns["QueryThreadGuid"],queryTable.Columns["QueryThreadGuid"]); dv = new DataViewManager(ds); I set a row filter to QueryThread table dv.DataViewSettings["QueryThreads"].RowFilter = "OpenClose = ''Automatic Open''"; Now when I try following code It returns undefined value in ''queryLevel'' variable. this.gridModel = this.gridDataBoundGrid1.Model; this.gridBinder = this.gridDataBoundGrid1.Binder; // Reduce flicker this.gridDataBoundGrid1.BeginUpdate(); gridModel.Options.AllowSelection = GridSelectionFlags.AlphaBlend|GridSelectionFlags.Row|GridSelectionFlags.Column|GridSelectionFlags.Keyboard|GridSelectionFlags.Shift; gridModel.Options.AllowDragSelectedCols = false; GridStyleInfo standard = gridModel.BaseStylesMap["Standard"].StyleInfo; standard.ShowButtons = GridShowButtons.ShowCurrentRow; standard.CellType = "Static"; this.gridDataBoundGrid1.DataMember = "QueryThreads"; this.gridDataBoundGrid1.DataSource = dv; GridHierarchyLevel queryLevel = this.gridDataBoundGrid1.Binder.AddRelation("QueryThreadQuery"); So following line generates exception. queryLevel.ShowHeaders = false; Is there solution or reason why it is not returning queryLevel? I checked with data.After filtering also there are rows in QueryThread table. Evenif I change the RowFilter to "" the same problem continues dv.DataViewSettings["QueryThreads"].RowFilter = "";

Try setting the grid.DataMember to be the parent tables'' name instead of the child tables name (if I understand what you want there). Here is a little sample that seems to work as expected. DataViewManager_8760.zip

I did the same. DataMember was assigned to ''QueryThreads'' which was parent table. I just called gridBinder.ResetHierarchyLevels(); and the problem was solved.
