DataGridContext rootContext = DataGridControl.GetDataGridContext(this.AssignmentsGrid);
List<DataGridContext> childContexts = new List<DataGridContext>(this.AssignmentsGrid.GetChildContexts());
foreach (DataGridContext context in childContexts)
{
context.ParentDataGridContext.CollapseDetails(context.ParentItem);
}
}
}
}

I have the Master Grid working fine which is corresponding to Assignments, but the detail grid doesnt show which is corresponding to Tasks. what could be missing in my code?
