redirecting result to one page to another

In the code behind (button click handler)

Response.Redirect("http://myotherpage.aspx")

Save your search result in session. And use this session on other page. For ex
save result in Session("ABC").
Then next page where you want to use create data table.
DataTable dt = new DataTable();
dt = Session("ABC");

Now all result in dt. And easily use DataTable value on this page.

A simple solution from your perspective would be to use Session.
On the click event of a search button, you will set session values to the values you want, ex.: Session["Search"] = search value;
On the receiving end, you simply read the value via Session["Search"].

                var keyValue = document.getElementById("Textbox1").value;
                location.href = 'Result.aspx?key=' + keyValue;
            }
        }
