Populate the data of nested table only on expand the list

Data gets loaded when the data source is assigned to GridGroupingControl by default. To populate the data of the nested table only on expanding the child table, use the property UseLazyUniformChildListRelation. It will optimize the performance. 

C#

//To populate the data of the nested table only on expand
this.grid.UseLazyUniformChildListRelation = true;

VB

'To populate the data of the nested table only on expand
 Me.grid.UseLazyUniformChildListRelation = True
