Passing Information from ListBox1 in Form1 to ListBox2 in Form2

Hee Lian

How do I pass values from a listbox in one form to a listbox in another form?

How my application works is that in Form1, after user enters a text into a textbox, the text will be added to the listbox1 when i press on a button. Afterwards, when i click another button to show Form2, the items in the listbox1 should be displayed in the listbox2 in Form2. How do I do this?

I only learned the basics of C# so i'm not sure how to go about doing this.

proceed as
form 1
private void button1_Click(object sender, EventArgs e)
{
     Form2 form = new Form2(listbox1.Items);
     form.Show();
}
form 2.
public partial class Form2 : Form
{

    public Form2()
    {
        InitializeComponent();
    }

    public Form2(ListBox.ObjectCollection objectCollection)
    {
        InitializeComponent();

        this.listBox1.DataSource =  objectCollection; // listbox1 of form2
    }
}
Done!
