One way is to put the values into the Session object and then read those fro the other page. You can wire up the OnClick event of the button and do something like:
protected void ImageButton1_Click(object sender, EventArgs e)
{
System.Web.HttpContext.Current.Session.Add("Key", "Value");
Response.Redirect("~/Careers_Search_results.aspx");
}
You can then get these values in the OnLoad event of the other page with:
protected override void OnLoad(EventArgs e)
{
if (!IsPostBack)
{
string data = System.Web.HttpContext.Current.Session["Key"].ToString();
}
}
That should get you started.
