vb.net - How to sort the sequence of checkbox -

i have 2 checkboxes. if check cb1 first , cb2 next, listbox should display data of checkboxes in order of checked sequence.

public class form1    private sub button1_click(sender object, e eventargs) handles button1.click     if cb1.checked = true , cb2.checked = false       listbox1.items.add(cb1.text)       if cb1.checked = true , cb2.checked = true         listbox1.items.add(cb1.text)       end if     elseif cb2.checked = true , cb1.checked = false       listbox1.items.add(cb2.text)       if cb2.checked = true , cb1.checked = true         listbox1.items.add(cb1.text)       end if     end if   end sub end class 

if 1 checkbox checked displays data, if both checked there's no data displayed in list box.

you're question not clear enough me sure of want here solution question interpreted:

your code checking if both true nested within if statements wouldn't run if both true. also, dont put end if @ end of elseif if have more criteria come.

fixed code:

private sub button1_click(sender system.object, e system.eventargs)         handles button1.click     if cb1.checked = true , cb2.checked = false         listbox1.items.add(cb1.text)     elseif cb1.checked = true , cb2.checked = true         listbox1.items.add(cb1.text)         listbox1.items.add(cb2.text)     end if      if cb2.checked = true , cb1.checked = false         listbox1.items.add(cb2.text)     elseif cb2.checked = true , cb1.checked = true         listbox1.items.add(cb2.text)         listbox1.items.add(cb1.text)     end if  end sub 

you have better luck if made event happen automatically after each 1 checked. code run once, if have 1 checked , code runs, if other 1 checked, code won't run again unless have in sort of loop (until loop work).
