How can I set  an input box ?

How can I set  an input box ?


During the trainning videos (chapter 4), I saw that in the OrderItemDetail, the OrderItem_Quantity field allowed the user to input negative values.
How can I set an input box that only accepts positive values ?

Kind regards

Hi Paulo,

You can do it using the onchange javascript function on the extended properties:

Hope this helps
