vb.net - Huge amount of textboxes repeated code -

-

i have around 200 textboxes in form. pressing "enter" takes next textbox. pressing "up" takes upper textbox, etc... know coding it's 200 textboxes it's gonna huge amount of copy/paste. there short way can 200 textboxes ?

you want show users 200 textboxes on single form? should @ least group them in container control logically, example in panel. use oftype.

you add constructor of form-class uses anonymous event handler:

dim alltextboxes = txt in me.textboxpanel.controls.oftype(of textbox)()                    order txt.tabindex dim txtlist = alltextboxes.tolist()  int32 = 0 txtlist.count - 1     dim thistxt = txtlist(i)     dim nextindex = if(i + 1 >= txtlist.count, 0, + 1)     dim previndex = if(i - 1 < 0, txtlist.count - 1, - 1)     dim nexttxt = txtlist(nextindex)     dim prevtxt = txtlist(previndex)      addhandler thistxt.keydown,          sub(txt object, e keyeventargs)             if e.keycode = 38 'up                 me.activecontrol = prevtxt             elseif e.keycode = 13 'enter                 me.activecontrol = nexttxt             end if         end sub next
