You just need to handle the OnSelectedIndexChanged event of the dropdownlist.

You don't need to set Autopostback on the dropdownlist. The OnSelectedIndexChanged event will be triggered during a postback, any postback, including one caused by the button.

One way to handle this is to package your webpart as a user control. Some like this approach when the control has more interactive elements such as this.

It is not really clear where this code should reside which is typical of MSDN.

You should check into you're apparent superiority complex.

Since you consider yourself to be better than anyone else you shouldn't need to be asking questions here. You should be the one writing the documentation and articles.

A class act to critize [sp] the skills of others when you can't solve a problem. It shows excellent character.

Prove it. Post some articles, show us what you have learned.You're just not worth the time so go away and solve this problem the old fashioned way, after all isn't your're motto "if want something done right, do it yourself."

public class DDLWebPart : WebPart
{
    protected override void CreateChildControls()
    {
        base.CreateChildControls();

        Button btn = new Button();
        btn.Text = "Click Me!";

        Controls.Add(btn);

        DropDownList ddl = new DropDownList();
        ddl.SelectedIndexChanged += new EventHandler(ddl_SelectedIndexChanged);

        for(int x = 0; x < 10; x++)
        {
            ListItem item = new ListItem("Item " + (x + 1), (x + 1).ToString());
            ddl.Items.Add(item);
        }

        Controls.Add(ddl);
    }

    public void ddl_SelectedIndexChanged(object sender, EventArgs e)
    {
        Label lb = new Label();
        lb.Text = ((DropDownList)sender).SelectedItem.Text;
        Controls.Add(lb);
    }
