Question

I thought Shown would be the answer. But it seems that not all controls are equal. A panel is shown immediately, while a label – not.

I have the following code:

public partial class Form2 : Form
{
    Panel p = new Panel() { BackColor = Color.Green };
    Label l = new Label() { Text = "abc", Location = new Point(0, 100) };

    public Form2()
    {
        Controls.Add(p);
        Controls.Add(l);

        Shown += new EventHandler(Form2_Shown);
    }

    void Form2_Shown(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(2000);
    }
}

Which, initially, shows this:

And after 2 seconds – this:

So how do I run code after “the second image”?

Answer 1

Add the following at the beginning of the event handler:

this.Update();
