Transferring data from Form2 (textbox2) to Form1 (textbox1)? [duplicate]

Answer 1

Try this ;)

On Form1:

private void button1_Click(object sender, EventArgs e)
    {
        Form2 frm2 = new Form2(textBox1.Text);
        frm2.Show();
        this.Hide();
    }

On form2:

public partial class Form2 : Form
{
    public string textBoxValue;
    public Form2()
    {
        InitializeComponent();
    }

    public Form2(string textBoxValue)
    {
        InitializeComponent();
        this.textBoxValue = textBoxValue;
    }

    private void Form2_Load(object sender, EventArgs e)
    {
        textBox2.Text = textBoxValue;
    }
