Redirect website in content holder

Ok,i got the iframe code here:
<iframe src="http://google.com"></iframe>

And the following back code:

protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Redirect("http://www.google.com/search?hl=en&q=" + TextBox1.Text.ToString() + "");  
        }

The back code runs as a new page in browser,where keyword entered in TextBox1 redirect to new google page to search for the keyword entered in TextBox1.

Now i want the back code function runs on the iframe,where the same function runs on the iframe.

Any ideas?

Try something like this

<iframe runat="server" id="iframe1" src=""></iframe>

.cs

protected void Button1_Click(object sender, EventArgs e)
    {
        iframe1.Attributes.Add("src", "http://www.google.com/search?hl=en&q=" + TextBox1.Text + "");
    }
