Hi Experts,

Scenario:
1) Create Self Referencing Hierarchy Grid using Sub Objects.
2) Structure of SubObjects
        ParentObject
                ChildDetailsObject
                RelationObject

        ChildDetailsObject    
                Name
                Details

        RelationObject
                Name
                ParentName
 3) We provide collection of ParentObject as datasource.

Clarification:
   1) Can we provide SubObjects are DataKeyNames in MasterTableView.
        ex: DataKeyNames = "ParentObject.RelationObject.Name, ParentObject.RelationObject.ParentName"
   2) Can we provide SubObjects in ParentKeyName and KeyName in SelfHierarchySettings.
        ex: ParentKeyName = "ParentObject.RelationObject.ParentName"
              KeyName = "ParentObject.RelationObject.Name"
  3) Code snippet or sample application would help to understand this better.

Regards,
Aayam Singh

Hello Aayam,

Nested properties are not supported with RadGrid self-referencing hierarchy. You can create a mapper object that will map a nested property to a first-level property in the grid. Attaching a test page that demonstrates this scenario. Note that I have defined a property ( RelationObjectParentName) that wraps the nested RelationObject.ParentName sub-property to use with the self-referencing hierarchy settings.
