RefreshDataAndView of detail model without collapse

[ksikes]

Following the Nested Grid demo for ParamQuery Pro I setup three levels of grids in the hierarchy of Departments, Categories, and Courses.  An on change event at the courses level refreshes data at the Departments level, but I find that I cannot refresh the view of the data in the nested grid, Categories programatically.  I find that if I collapse the Categories grid and expand it again, the underlying data is refreshed and renders properly.

I am calling "refreshDataAndView" at the top level grid, i.e. $("#grid_Department").pqGrid("refreshDataAndView");
I expected the call to refresh would trickle down through the nested grid(s) but it does not seem to do so.

Wondering if there is a way to call the refresh directly to the nested grid but I am unable to determine the proper selector to use.
Is there  a built in method to programatically force the refresh of a nested grid?  If not, can we programatically collapse and expand a nested grid to force the refresh?

Thanks in advance for any insight you can provide.

Reference to detail grid is stored in corresponding parent row as.

Code: [Select]

  var child = rowData.pq_detail.child.pqgrid( 'instance' );

  child.refresh();  //refresh the nested grid.

For anyone who does what I did and copy and paste the reply code sample above, please be aware of the small typo pqgrid should read pqGrid (note upper case G).

var child = rowData.pq_detail.child.pqGrid( 'instance' );
