Hi I'm trying to create a parent/child view with DevExpress.XtraGrid.Views.Grid.GridView using a custom entity.  My custom entity inherits BindableList(Of CustomType) The CustomType class have many properties that are entities objects IE: Class BindableType (inherits BindableList(Of CustomType)) Class CustomType Property EntityTypeOne (DevForce Entity) Property EntityTypeTwo (DevForce Entity) Property EntityTypeThree (DevForce Entity) Using IdeaBlade.UI.WinForms.DevExpressControls.XtraGridBindingManager an object of "BindableType" type fill my grid without any problem. I created all EntityPropertyDescriptors related to my "CustomType" properties. Now i'm trying to "AddRelationView" to my main grid without success. The relation is between "CustomType.EntityTypeTwo.ID" and "EntityTypeFour.ID" I'm not able to create the EntityRelation because i do not have any EntityColumns belongs to my "CustomType". There is a way to AddRelationView from a custom type? As usual thanks in advance!  |
