How to pass Form 1 listview value to the Form 2 textbox?

Question

I am new to c# and I am writing a simple application that want to pass Form 1 listview value to the Form 2 textbox. So how can I pass these subitem to the Form 2 textboxes?

 private void Form1_Load(object sender, EventArgs e)
        {
            ListViewItem item = new ListViewItem("ITEM1");
            item.SubItems.Add("ITEM2");
            item.SubItems.Add("ITEM3");
            listView1.Items.AddRange(new ListViewItem[] { item });
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form2 newForm = new Form2();
            newForm.Show();
        }

See my two form project on following webpage. You need to call a method in Form2 that take an input from form1. http://stackoverflow.com/questions/37366447/keep-checked-radio-button-checked-through-forms-c-sharp-visual-studio-2010/37366641#37366641 — jdweng, May 21 '16 at 20:04

To do this you need to declare property in your Form2 class:

public class Form2
{
    public ListViewItem[] Items{get;set;}

    //your code
}

then you can pass listView1.Items to form2:

private void button1_Click(object sender, EventArgs e)
{
    Form2 newForm = new Form2();
    newForm.Items = listView1.Items; // pass items to form2
    newForm.Show();
}

and then in form2 load event handler get necessary values and set it to textboxes of form2:

public class Form2
{
    public ListViewItem[] Items{get;set;}

    private void Form2_Load(object sender, EventArgs e)
    {
        textBox1.Text = Items[0].SubItems[0].Text; // or your logic here in this handler            
    }

    //your code
}

You can modify Form2's constructor like this

public partial class Form2 : Form
{
    public Form2(ListViewItem item)
    {
        InitializeComponent();
        textBox1.Text = item.Text;   // item.Subitems[index].Text if you want the value of subitems
    }
}

And when you create your form, you pass in the item like so

private void createNewForm()
{
    Form2 f = new Form2(listView1.Items[0]); // to pass the first item in this case
    f.Show();
}
