如果列的值为 0，如何隐藏行 - 使用 C#(WPF)，SQL

Question

I am doing a project that let the students add books. And for these books there is quantity that shows how much quantity do the library have of a selected book. So my question is that When Book quantity have (0) value I want the book to be hidden from the dataGridView so student can't see it.

How do hide the row of the book that has 0 value?

C#, WPF, SQL
