Okay first part done now I need to add 2 variables to my session state for this pop up.


protected void Button2_Click(object sender, EventArgs e)
        {
//The first session and responce.redirect works fine 
//first session
            Session["SessionParkID"] = dltName.SelectedValue;
            first// respnce
       //     Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + Session["SessionParkID"].ToString(), "_PDF", "menubar=0,width=100,height=100");
//added a second variable to the mix
Session["ProcSes"] = "P_sp_GrabDoc1";
//this is the new responce.redirect the page loads but the pop up does not... anyone got any ideas?
            Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + Session["SessionParkID"].ToString() + Session["ProcSes"].ToString(), "_PDF", "menubar=0,width=100,height=100");

Open in new window

protected void Page_Load(object sender, EventArgs e)
        {
            testinglablesession.Text = Request.QueryString["ID"].ToString();

Once the first "Response.Redirect" is hit, all other code is useless. It won't get processed and will never take affect. A Response.Redirect will IMMEDIATELY send the current process to the page you specify. If you want both sessions set you will have to do:

Session["SessionParkID"] = dltName.SelectedValue;
Session["ProcSes"] = "P_sp_GrabDoc1";

Response.Redirect(...);

I don't think this is what you want because you are trying to prompt for two downloads, this is not possible the way you are trying. As mentioned about the first response.redirect will take affect and the second will NEVER be hit.

You have several options if you need multiple downloads...
1) Zip the downloads together and send them as one ZIP file download
2) Open new browser windows on the click action that starts this process (i.e. <a href="..." target="_blank">First Download</a>). This requires two links to be clicked.

I have played with it more but I am not trying to do two downloads at once just a little more specifice in my string.

From the code below it hits my first responce redirect string fine if I only have one session variable and Save the session variable but form sone reason when I add he second it does not want to save it....

Am I doing something wrong in my response.redirect query string?

//original
           // Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + Session["SessionParkID"].ToString(), "_PDF", "menubar=0,width=10000,height=10000");
          //trial
            Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + Session["SessionParkID"].ToString() +"&Proc="+ Session["ProcSes"].ToString(), "_PDF", "menubar=0,width=10000,height=10000");

Session["SessionParkID"] = dltName.SelectedValue;
            label2.Text = "P_sp_GrabDoc1";
            Session["ProcSes"] = label2.Text;
            //original
           // Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + Session["SessionParkID"].ToString(), "_PDF", "menubar=0,width=10000,height=10000");
          //trial
            Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + Session["SessionParkID"].ToString() +"&Proc="+ Session["ProcSes"].ToString(), "_PDF", "menubar=0,width=10000,height=10000");

Ok, it makes a little more sense. My first question is: why are you setting session variable and then adding those to the query string? You should be able to access the session variables on the download page without the need for the querystring:

public partial class Downloads : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
//Check for null sessions here otherwise errors can occur
            testinglablesession.Text = Session["SessionParkID"].ToString();
            lblDownloadNumber.Text = Session["ProcSes"].ToString();
}
} 

Open in new window


Next question, if you need the querystring, what set the session?

Session["SessionParkID"] = dltName.SelectedValue;
            label2.Text = "P_sp_GrabDoc1";
            
Response.Redirect("/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + dltName.SelectedValue +"&Proc="+ label2.Text, "_PDF", "menubar=0,width=10000,height=10000"); 

Open in new window


Lastly, make sure to step through your code and make sure that the values exist, easiest way:

Session["SessionParkID"] = dltName.SelectedValue;
            label2.Text = "P_sp_GrabDoc1";
      String temp = "/ics/Portlets/CUS/ICS/PARK_GradeAppeal_v1_5_27_2011/Downloads.aspx?ID=" + dltName.SelectedValue +"&Proc="+ label2.Text;

Response.Redirect(temp, "_PDF", "menubar=0,width=10000,height=10000");

Hello,

protected void Page_Load(object sender, EventArgs e)
        {
            testinglablesession.Text = Request.QueryString["ID"].ToString();

            lblDownloadNumber.Text = Request.QueryString["ProcSes"].ToString();
}

testinglablesession.Text = Request.QueryString["ID"].ToString() '" +',' + "'
Request.QueryString["ProcSes"].ToString(); //In C#


testinglablesession.Text = Request.QueryString("ID").ToString() & "," &
Request.QueryString("ProcSes").ToString(); //In VB
