This a couple of things that need to be changed to get your ListBox working the way you want it. To your names class reverse the order of the arguments being passed to your constructor.

Like this:

			public names(string strnickName, string strrealName)

Put the following code in your Load Event.

			ArrayList names1 = new ArrayList();
			names1.Add(new names("Mary", "Sis"));
			names1.Add(new names("Joe", "Bubba"));
			names1.Add(new names("Lynn", "Mom"));
			names1.Add(new names("Fred", "Dad"));
			names1.Add(new names("Sandy", "dog"));

			listBox1.DataSource = names1;
			listBox1.DisplayMember = "nickName1";

As far as the rest of the code you are asking about. You are going to have to explain what you are trying to do. Currently, you are trying to assign values to the ListBox and you can't do this when it is tied to a data source.

Ok.

I'm sorry for not being more clear. All this searching and trying different things that don't work is
a little confusing.

Thank you all for trying to help.

Here is exactly what I want to do, with whatever code that will work, whether I already have it or not:

1. In addition to adding items to the listbox, assign a value other than index to each of those items.
2. Display (wherever--as long as it works) the selected items. (Using whatever works, to check that each item is associated with a different value)
I want to be able to access either one. If I put (something?) in the code, the value will be displayed, and if I put (something else?) in
the code, the item itself will be displayed. (In a label, messagebox, textbox or whatever).

These two things are really all I need to do. The rest is just things I wondered about or tried to do.


Is that better?

Crap. I still can't understand what you're trying to do.

I'm cooking something up, try it out and see if that's what you want it to do.

Here it is:

namespace WindowsFormsApplication1
{
	public partial class Form1 : Form
	{
		public Form1()
		{
			InitializeComponent();
		}

		private void button1_Click(object sender, EventArgs e)
		{
			if (textBox1.Text != "")
			{
				this.listBox1.Items.Add(this.textBox1.Text);
			}
			else 
			{
				MessageBox.Show("Please write something to add to the listbox.");
			}

		}
	}
}

What it does is copy the text the user writes in the textbox into the listbox, automatically assigning an index value. Is this what you want? Edit: Now the user can't copy anything into the listbox if textbox is left blank.

No...I wasn't looking for that exactly...although it is good to get different ideas, and try different approaches to the problem.
After rereading it, I see what you did...let the user add their own items to the listbox. Neat.
I do appreciate you trying to help me.



jayman9,
Your code (post #16) works. I think that is what I wanted to do, and using the suggestion from n8wxs, I think I've finally
got it!!!

			//display selected items in a label and in a messagebox, one at a time
				foreach (int index in listBox1.SelectedIndices)
				{
					MessageBox.Show(listBox1.Items[index].ToString());
					label1.Text += listBox1.Items[index].ToString() + Environment.NewLine;
				}

Thank you so much, all of you who've been helping me.

you are trying to assign values to the ListBox and you can't do this when it is tied to a data source.

?
...but it works...I think.

Do you mean that there is another way to assign values to the ListBox?

Can you do this without a data source?

I found out the answer.
No...you can't.

But you can do it without the 'get' and 'set'.
