Question is not clear to me. What do you want to accomplish from this. Why you want to change bgColor?

I'm not sure what you're asking. Do you want to swap the colors periodically? Or have it look more like "chaser" mode on christmas lights? Is this ASP.Net, WPF, or Windows Forms? If ASP.Net does it need to be client side or server side?

asp .net at client side

you can use JavaScript for that. Below is sample.
var txt1bgColor= document.getElementById("<%=TextBox1.ClientID%>").style.backgroundColor;

document.getElementById("<%=TextBox2.ClientID%>").style.backgroundColor = txt1bgColor;

You are not going to do this in C#, try javascript.

Hi,

As ThePhantomUpvoter said, you should try to do this with JavaScript, not with C#.
Try this:

ASP

<form runat="server">
    <asp:TextBox runat="server" BackColor="Red" ID="textbox1" />
    <asp:TextBox runat="server" BackColor="Green" ID="textbox2" />
    <asp:textbox runat="server" BackColor="Blue" ID="textbox3" />
</form>
<script type="text/javascript">
    var txtbox1 = document.getElementById("<%=textbox1.ClientID%>");
    var txtbox2 = document.getElementById("<%=textbox2.ClientID%>");
    var txtbox3 = document.getElementById("<%=textbox3.ClientID%>");
    setInterval(function () {
        prevColorTxt1 = txtbox1.style.backgroundColor;
        prevColorTxt2 = txtbox2.style.backgroundColor;
        prevColorTxt3 = txtbox3.style.backgroundColor;
        txtbox2.style.backgroundColor = prevColorTxt1;
        txtbox3.style.backgroundColor = prevColorTxt2;
        txtbox1.style.backgroundColor = prevColorTxt3;
    }, 5000, null);
</script>

Hope this helps.

C#

static int flag = 0;
    static int counter = 1;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (flag == 0)
        {
            TextBox1.BackColor = System.Drawing.Color.Red;
            TextBox2.BackColor = System.Drawing.Color.Green;
            TextBox3.BackColor = System.Drawing.Color.Blue;

            flag = 1;
            counter = 1;
        }
    }
    protected void Timer1_Tick(object sender, EventArgs e)
    {
        if (counter == 1)
        {
            TextBox1.BackColor = System.Drawing.Color.Blue;
            TextBox2.BackColor = System.Drawing.Color.Red;
            TextBox3.BackColor = System.Drawing.Color.Green;
            counter = 2;
        }
        else if (counter == 2)
        {
            TextBox1.BackColor = System.Drawing.Color.Green;
            TextBox2.BackColor = System.Drawing.Color.Blue;
            TextBox3.BackColor = System.Drawing.Color.Red;
            counter = 3;
        }
        else if (counter == 3)
        {
            TextBox1.BackColor = System.Drawing.Color.Red;
            TextBox2.BackColor = System.Drawing.Color.Green;
            TextBox3.BackColor = System.Drawing.Color.Blue;
            counter = 0;
            flag = 0;
        }
    }

Hi! I use Winform to do this task

private void Form1_Load(object sender, EventArgs e)
{
timer1.Interval = 5000;
timer1.Tick += new EventHandler(timer1_Tick);
timer1.Start();

}

void timer1_Tick(object sender, EventArgs e)
{
Color temp1 = textBox1.BackColor;
textBox1.BackColor = textBox3.BackColor;

Color temp2 = textBox2.BackColor;
textBox2.BackColor = temp1;

Color temp3 = textBox3.BackColor;
textBox3.BackColor = temp2;
}
