Passing and retrieving StringQuerys

Question

I have to pass two query strings that i've entered and display them on another page.

Here is the code where i attempt to pass them.

protected void btnDisplay_Click(object sender, EventArgs e)
    {
        string vacations = Session["Vacations"] as string;
        string hobbies = Session["Hobbies"] as string;
        string classes = Session["Classes"] as string;

        lblDisplay.Text = "Your favorite vacations spots are: " + vacations + "<br />" +
        "Your hobbies are: " + hobbies + "<br />" +
        "Your IT Classes are: " + classes;

    }
    protected void btnRedirect_Click(object sender, EventArgs e)
    {
        string vacations = Request.QueryString["vacations"];

        Response.Redirect("Summary2.aspx?vacations=" + vacations);
    }

Here is where I attempt to retrieve and display them.

protected void btnDisplay_Click(object sender, EventArgs e)
{


    lblDisplay.Text = Request.QueryString["vacations"];

}

I can't figure out what I am doing wrong. When i hit the Display button on my 2nd page, nothing shows up. Which I am assuming I am not passing the information correctly.

PS The information that is trying to be passed is the session states on the stop of my code. I only need to send the vacations and the classes through the query string.

Answer 1

you need to take the vacations value from session. you're reading it from the query string on the first page.

protected void btnRedirect_Click(object sender, EventArgs e)
{
    string vacations = Session["vacations"] as string; // this line
    string classes = Session["vacations"] as string;

    Response.Redirect("Summary2.aspx?vacations=" + vacations + "&classes=" + classes);
}

Answer 2

I think you want to send two parameters. (Your question is a little confused)

I hope this can help you.

So, In your webForm 1, add one button and write this small code:

Session["Vacations"] = "sample 1";
Session["variable2"] = "variable 2";
string vacations = Session["Vacations"] as string;
string variable2 = Session["variable2"] as string;
string myquery = vacations + "/" + variable2;
Response.Redirect("WebForm2.aspx?myquery=" + myquery);

In your webForm 2, In the "load" event add this code:

string data = Request.QueryString["myquery"];
string[] words = data.Split('/');
foreach (string word in words)
{
    Response.Write(word);
}

It is a way to pass two parameters between two web pages.
