How to change button color using tag or name property

[ixilom]

---EDIT----
You never assign anything to your .Tag property :P


I cant see why it wouldn't work except that in your web application you are looking for controls in panel1, whilst in your forms app you refer to this.Controls. Is "this" refering to the form or panel1 ?

I did a simple test

        private void button1_Click(object sender, EventArgs e)
        {
            button1.BackColor = Color.Yellow;
        }

That changes the color of the button without any problems. Can you place a breakpoint in your code where it is supposed to change the color and see that it is actually being executed?
