I am trying to hide some of the columns from the relationship based on parent property value, I have tried below code:
parent.findCurrentRelationshipsTab().grid.setColumnVisible(ColumnIndex, false, 150);
however, this is working when Item is loaded, I want this on onFormPopulate.
I am getting the parent.findCurrentRelationshipsTab().grid as null/empty.
Is there any way to get the relationship grid.
