Question

Hi i am having 2 forms on a application, and want to use one form to set a label in a an other form, i looked around for an answer, but i didn’t got it working. code:

form 1

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

        private void uit_Click(object sender, EventArgs e)
        {
            Form2 frm = new Form2(this);
            frm.Show();
        }

        public string LabelText
        {
            get { return uit.Text; }
            set { uit.Text = value; }
        }

    }

form 2:

public partial class Form2 : Form
{
    private Form1 mainForm = null;
    public Form2(Form callingForm)
    {
        mainForm = callingForm as Form1;
        InitializeComponent();
    }
    private void Form2_Load(object sender, EventArgs e)
    {
        txtmessage.Text = this.mainForm.LabelText;
    }
    public void button1_Click(object sender, EventArgs e)
    {
        this.mainForm.LabelText = txtmessage.Text;
    }
}

could someone explain why this doesn’t work?

I’ve just built it and it works fine. I’m assuming that you’ve got the events hooked up?
