Array elements displayed in Listbox are displayed not correctly

Question

First of all; I cannot use list. It has to be a array for school purposes. I have a string[] Brands = new string[10]; Four elements of this array are already filled when the form is initialized. The empty elements can be filled by adding textbox value to array with btnclick I'm displaying the filled elements in a listbox. The problem is that the listbox displays it like this:

Kawasaki
Yamaha
Harley
Suzuki

It needs to be displayed like this: Kawasaki Yamaha Harley Suzuki (when i click the buttun it needs to the already existing elementsd like this)
Kawasaki Yamaha Harley Suzuki (the added value1)

Another btnclick:
Kawasaki Yamaha Harley Suzuki (the added value1) (the added value2)

I know I need to use a for loop in my btnclik but I don't know how. This is what I currently have in my btnclick event:

if (brandNr >= 10)
   return;

Brands[brandNr++] = textBoxBrand.Text;
listBoxMotorcycles.DataSource = null;
listBoxMotorcycles.DataSource = Brands;

Why are you using a listbox if you don't want to display the elements as a list? — Pikoh

I know it's strange but I need to use it like this for school. I need to use a array with fixed length > add values to aray with textbox > display the values in a listbox — Needsomehelp

The listbox displays the values as a list but it needs to display it as increments. — Needsomehelp

I really doubt in your school make you use a listbox to display elements horizontally,just doesn't make sense to me..you should use a textbox or a label for the output array — Pikoh

first of all make sure that for form is wider enough, then on the load event you can write this code

 Brands[0] = "Kawasaki";
 Brands[1] = "Yamaha";
 Brands[2] = "Harley";
 Brands[3] = "Suzuki";
 listBoxMotorcycles.MultiColumn = true;
 listBoxMotorcycles.ColumnWidth = 100;
 listBoxMotorcycles.Width  = 400;
 listBoxMotorcycles.Height = 20;
 listBoxMotorcycles.DataSource = Brands;

and on the button click event your code must be he follwing

if(listBoxMotorcycles.Items.Count < Brands.Length)
{
    Brands[listBoxMotorcycles.Items.Count] = textBox1.Text;
    listBoxMotorcycles.DataSource = null;
    listBoxMotorcycles.DataSource = Brands;

    textBox1.Text = string.Empty;
}
