Return values from dialog box

Question

how to send and return values in modal dialog form

Answer 1

This is how I would call the dialog box

 var regStoreForm = new RegisterStoreForm(storeID,password);
            if (regStoreForm.ShowDialog(this) == DialogResult.OK)
            {
                storeID = regStoreForm.StoreId;
                password = regStoreForm.StorePassword;
            };
            regStoreForm.Dispose();

And this is what the Dialog box looks like

 public partial class RegisterStoreForm : Form
    {
        public int StoreId { get; set; }
        public String StorePassword { get; set; }

        public RegisterStoreForm(int storeId,string password)
        {
            InitializeComponent();
            StoreId = storeId;
            StorePassword = password;
            this.textBoxPassword.Text = StorePassword;
            this.textBoxStoreId.Text = StoreId.ToString();
        }

        private void OKbutton_Click(object sender, EventArgs e)
        {
            StoreId = Convert.ToInt16(textBoxStoreId.Text);
            StorePassword = textBoxPassword.Text;
            this.DialogResult = DialogResult.OK;
            this.Close();
        }
    }
