.aspx:

.cs:

protected void Page_Load(object sender, EventArgs e)
{
    if (Page.IsPostBack)
        return;

    if (!string.IsNullOrEmpty(Request.QueryString["SearchTerm"]))
    {
        string searchTerm = Request.QueryString["SearchTerm"];
        txtSearchTerm.Text = searchTerm;
        DoSearch(searchTerm);
    }
}
protected void btnSearch_Click(object sender, EventArgs e)
{
    if (!string.IsNullOrEmpty(txtSearchTerm.Text.Trim()))
    {
        Response.Redirect("~/Search.aspx?SearchTerm=" + txtSearchTerm.Text.Trim());
    }
}

private void DoSearch(string searchTerm)
{
    //search logic here
    Response.Write("Search result: " + searchTerm);
}
