Let me explain the problem.

Take this example: http://www.igniteui.com/hierarchical-grid/load-on-demand 

I want to implement a functionality that takes an array of primarykeys, where each index represents the levels, and after that the corresponding rows will be opened and highlighted.

Explanation:

1) Call function with ['Beverages','Chang'], it should expand the parent row of primary key with value 'Beverages' and highlights the row with primary key value 'Chang'
2) Call function with ['Confections'], it should highlight the row with primary key value 'confections'
3) call function with ['Condiments','Aniseed Syrup','Some Other']: If grid would have been of 3 levels, then the root row with value of primary key as 'Condiments' would have been expanded, inside it row with value of primary key as 'Aniseed Syrup' will be expanded and child row with 'Some Other' as value of key will be highlighted.

Hope I am clear with my requirement.

Is it possible to achieve this in igHieararchical Grid?

Thanks
