Take a look at the \Syncfusion\Essential Suite\3.0.1.0\Windows\Grid.Windows\Samples\Quick Start\GridControlSort sample.
It shows how you can use a custom comparer to sort a column. In your case, when you sorted the primary column, your custom comparer would check if the sort keys are equal. If so, you would then base the comparision on your secondary key.
