Subgrid records not able to fetch from different tab in crm 365 9.2 online

Hi All,

I am restricting to move to next bpf stage if theres no records in one subgrid avilable in the form , however its not restricting until unless not clicking on that tab where subgrid in present in that tab.

formcontext.getControl("subgridname").getGrid().getTotalRecordCount();

How can we resolve this issue ?

Thanks,
