Attached is simple project, dataset with 2 small related tables. I am trying to manually configure columns for nested tables in DataBoundGrid, however if I manually add column to GridHierarchyLevel, the data is not displayed (even though header has correct text). Quick analysis shows that generated Internal Column for nested table is missing the Property Descriptor (parent table is generated and displayed properly), even though I do explicitly call Binder.InitializeColumns(); Please help ? sample_5155.zip

Instead of trying to populate level.GridBoundCOlumns with new GridBoundColumns, try using level.LayoutColumns. This will just use teh columns that are already there and move them into level.GridBoundColumns. Below is your formload with this done. It displays 1 column at both teh parent and child level for me. private void Form1_Load(object sender, System.EventArgs e) { dataset11.Loadtag_Record.AddLoadtag_RecordRow(1, "123", 1, 1); dataset11.Loadtag_Record.AddLoadtag_RecordRow(2, "456", 1, 1); dataset11.Loadtag_Data.AddLoadtag_DataRow(dataset11.Loadtag_Record[0], 1, "1"); dataset11.Loadtag_Data.AddLoadtag_DataRow(dataset11.Loadtag_Record[0], 2, "2"); dataset11.Loadtag_Data.AddLoadtag_DataRow(dataset11.Loadtag_Record[1], 3, "3"); dataset11.AcceptChanges(); gridDataBoundGrid1.DataSource = dataset11.Loadtag_Record; ////// Syncfusion.Windows.Forms.Grid.GridHierarchyLevel lvl = gridDataBoundGrid1.Binder.AddRelation(dataset11.Loadtag_Record.ChildRelations[0].RelationName); ////// Syncfusion.Windows.Forms.Grid.GridBoundColumn parentColumn = new Syncfusion.Windows.Forms.Grid.GridBoundColumn(); ////// parentColumn.MappingName = "OrderID"; ////// parentColumn.HeaderText = "OrderID"; ////// gridDataBoundGrid1.GridBoundColumns.Add(parentColumn); // Without next 4 lines grid works, but displays all 4 columns, // What to do if I want only one? ////// Syncfusion.Windows.Forms.Grid.GridBoundColumn childColumn = new Syncfusion.Windows.Forms.Grid.GridBoundColumn(); ////// childColumn.MappingName = "LoadNumber"; ////// childColumn.HeaderText = "LoadNumber"; ////// lvl.GridBoundColumns.Add(childColumn); Syncfusion.Windows.Forms.Grid.GridHierarchyLevel lv0 = this.gridDataBoundGrid1.Binder.RootHierarchyLevel; lv0.LayoutColumns(new string[]{"OrderID"}); Syncfusion.Windows.Forms.Grid.GridHierarchyLevel lvl = gridDataBoundGrid1.Binder.AddRelation(dataset11.Loadtag_Record.ChildRelations[0].RelationName); lvl.LayoutColumns(new string[] {"LoadNumber"}); ////// gridDataBoundGrid1.Binder.InitializeColumns(); gridDataBoundGrid1.Refresh(); }
