Hi, I have got 2 hierarchies of datatable formatted in an ExpandGrid strucutre in BoundDataGrid. I can set properties such as header text of the root hierarchy by, this.gridDataBoundGrid1.Binder.GridBoundColumns however how can i manipulate on the dataColumns of the lower hierarchy? can i only show the headers of the lower hierarchy but not those in the root hierachy? Thanks for help

Hi Vincent, You can access the child levels with the GridHierarchyLevel class. Here is some code that sets the child and grand child''s columns header text and the celltype(style property). GridHierarchyLevel hlParentToChild = this.gridDataBoundGrid3.Binder.AddRelation("ParentToChild"); GridHierarchyLevel hlChildToGrandChild = this.gridDataBoundGrid3.Binder.AddRelation("ChildToGrandChild"); GridHierarchyLevel hlParent = this.gridDataBoundGrid3.Binder.RootHierarchyLevel; hlParentToChild.InternalColumns["childID"].HeaderText = "NewChilID"; hlParentToChild.InternalColumns["childID"].StyleInfo.CellType = "ComboBox"; hlChildToGrandChild.InternalColumns["GrandChildID"].HeaderText = "NewGrandChildID"; hlChildToGrandChild.InternalColumns["GrandChildID"].StyleInfo.CellType = "ComboBox"; You can hide the child level header''s by setting the showheaders property. hlParentToChild.ShowHeaders = true; hlChildToGrandChild.ShowHeaders = true; But to hide the parent header, you can just hide that particular header row. this.gridDataBoundGrid3.Model.Rows.Hidden[0] = true; Attached is a sample showing this implementation.
