Hi i have this problem, i have a CustomListView with have: btnAdd buton, btn+ & btn- button and a txtQty textbox with quantity value (picture attached)

And then when i click btnAdd_Click had the value of the textbox in this item

I create a class for each row, with its own graphical interface (a panel with its controls), in which I implement all the events and functionalities. Do a loadlayout to load interface
each of these elements that I create dynamically, is added to the list and implements everything that is needed inside it.
the listview acts as a container and manages the elements.
I hope it will be useful to you

Without seeing any code all I can suggest is to get the button's parent panel then knowing the textbox is a child control of that panel, use the panel to get a reference to the textbox and do whatever you like with the text box
