RE: Auto Populate Sub grid
Hi ,
What is the field type which you are changing? If it's lookup the you can do this using quick view form. Let's have an example you have a product lookup and you want to show all products items in a subgrid of another entity. To do this you can follow below steps-
-- Create a quick view forms in the product entity entity .
-- Add the product items subgrid in the quick view forms of product.
-- Include the quick view forms in which entity you want to display subgrid. You should have product lookup there in this entity.
-- Now on change the lookup value quick view form will render related product items in the subgrid.
