asp.net - How can I access div in a page from another page?

Question

I have a div in a script named: firstpage.aspx with an onclick button to go to secondpage.aspx. From secondpage.aspx I want to access a div on firstpage.aspx and change it's inner html, inner text, and control.

You can access PreviousPage if you have used Server.Transfer, not Response.Redirect. Here's how I would acess it: In the first page set runat="server" for the div:

<div id="myDiv" runat="server">My First Div</div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

And in the code behind:

protected void Button1_Click(object sender, EventArgs e)
{
    Server.Transfer ("secondpage.aspx");

}

In the second page I am catching the div using FindControl:

 public partial class secondpage: System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            HtmlGenericControl myDiv = (HtmlGenericControl) Page.PreviousPage.FindControl("myDiv");
            Label1.Text = myDiv.InnerText;
        }
    }
