Data gets loaded when the data source is assigned to WinForms 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.

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

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