Question

I have created some new method:

void newMethod(int x, int y)
{
    Button B = new Button();
    B.Size = new Size(100, 30);
    B.Location = new Point(x, y);
    B.Text = "Text";
    Controls.Add(B);
}

Now I created a new panel inside some other method:

void Something()
{
    Panel P = new Panel();
    P.Size = new Size(300, 300);
    P.Location = new Point(0, 0);
    P.BackColor = new Color(Blue);
    Controls.Add(P);
}

How do I add my first method in which I’ve created a button, to a panel in my second method?

Answer 1

Add the parent control as parameter:

private void AddButton(int x, int y, Control parent)
{
    Button button = new Button
        {
            Size = new Size(100, 30),
            Location = new Point(x, y),
            Text = "Text"
        };

    parent.Controls.Add(button);
}

Then:

void Something()
{
    Panel P = new Panel();
    P.Size = new Size(300, 300);
    P.Location = new Point(0, 0);
    P.BackColor = new Color(Blue);

    this.AddButton(100, 100, P);
}
