I don't understand your question.. Could you explain a little bit more?

[Microguy]

when I have a listBox and type something, it automaticly come a 1. in the first line, and if I start on a second line, it comes 2.
That will be very useful for what im making :)
I hope you understand :)

Ahhhh!!

Now i get it.

Here is an article that has exactly the thing you're looking for:
Numbering lines of RichTextBox in .NET 2.0 - CodeProject

And here is another i just found.
LineNumbers for the RichTextBox - CodeProject

richtextbox..? ok, thanks but I was looking for listBox :)

[TheCompBoy]

Here is two solutions i found for ListBox:

1) ListBoxRowNumbers lets you add Row Numbers to your ListBox or Combo control
ListBoxRowNumbers

2) Add line/row numbers to the underlying rowsource.
RowNumber

hmm, i downloaded it, but where do I place the file and use the code?

[TheCompBoy]

I can't answear that question, Sorry..

The point is that you should read the page through and the code too and learn from it.
I don't do copy & paste so i can't help you on that one.

Hope that you understand.

Are you familiar with "for" loops?

If so, you can easily create what you are looking for by seeing the sequence you have listed above:

1.item1
2.item2

there is a distinct pattern. I would use string concatenation to create each item.

[Microguy]

Hmm, im sorry but what do you mean?

I mean, have you learned "for" loops yet.

A simple for loop will allow you to add the number to the front and back of each text item, then add them to the list.

Uhhm, no :P
