c# add label from form2

Question

Form2 code:

public void button2_Click(object sender, EventArgs e)
        {   
          Form1 form1form = new Form1();
            Label asd = new Label();
         


        

Answer 1

If you want to access form1form from form2form you must have public reference to form1form. Declare property in form1form like below:

public static form1form Instance { get; private set; }

Then set Instance in Load event of form1form:

private void form1form_Load(object sender, EventArgs e)
{
   Instance = this;
}

In form2form:

public void button2_Click(object sender, EventArgs e)
{
    Label asd = new Label();
    asd.Text = "asdasasdasdasd";
    form1form.Instance.Controls.Add(asd);
}
