C# Passing a value a new form

Question

I got windows form am trying to pass value from that form to new one, when an button is clicked. using:

Click to copy

private void Edit_button_Click(object sender, EventArgs e)
        {
             for (int i = 0; i < listBox1.SelectedItems.Count; i++)
            {

             Edit item = new Edit(int.Parse(listBox1.SelectedIndex.ToString()));
            item.ShowDialog();

            }
        }

When I run the program it doesn't show the form I designed it shows this instead

But when i change the code to this:

Click to copy

 Edit item = new Edit();
   item.ShowDialog();

run it, it display the right thing, but doesn't pass a value to the second form.

I there a way to pass a value to another form?

Answer 1

Add a property

Click to copy

Edit item = new Edit();
item.Value = 5;
item.ShowDialog();

EDIT:

You have to define this property to use it. Extend your Edit class like that:

Click to copy

class Edit {
    ...
    public int Value { get; set; }
    ...
}

Answer 2

Just a guess: In your own Constructor you forgot to call IntializeComponents().
