I am trying to add a new label when clicking on a button. Shouldn\'t be too difficult but I just can\'t get it working :(

I am trying to add a new label when clicking on a button. Shouldn't be too difficult but I just can't get it working :(

private void button3_Click(object sender, EventA开发者_运维技巧rgs e)
    {
        Label Label10 = new Label();
        Label10.Location = new Point(23, 100);
        Label10.Text = textBox1.Text;
        Parent.Controls.Add(Label10);
    }

I get an error when trying to debug it with a not too explicit message:

"NullReferenceException was unhandled."

Not sure to what it may be referring... I am using the "new" keyword to create the new instance, what may I be missing?

Thanks!


Is Parent null? It could be on there too. You might just call this.Controls.Add(...).


textbox1 is probably what's throwing that exception. Can you step through your code in the debugger?
