ParamQuery Pro Evaluation Support / RefreshDataAndView of detail model without collapse

« on: September 20, 2016, 02:09:50 am »

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.
