Question

I’m supposed to change the frmPersonnelVerified code behind to get the values from the Session state items.

Here is my session state code:

public partial class frmPersonnel : System.Web.UI.Page 
{ 
    protected void btnSubmit_Click(object sender, EventArgs e) 
    { 
        try 
        { 
            //Checking validation for the text boxes 
            if (string.IsNullOrEmpty((txtFirstName.Text ?? string.Empty).Trim())) 
            { 
                txtFirstName.BackColor = System.Drawing.Color.Yellow; 
                lblError.Text += "Please enter first name! <br />"; 
            } 

            if (string.IsNullOrEmpty((txtLastName.Text ?? string.Empty).Trim())) 
            { 
                txtLastName.BackColor = System.Drawing.Color.Yellow; 
                lblError.Text += "Please enter last name! <br />"; 
            } 
            if (string.IsNullOrEmpty((txtPayRate.Text ?? string.Empty).Trim())) 
            { 
                txtPayRate.BackColor = System.Drawing.Color.Yellow; 
                lblError.Text += "Please enter pay rate! <br />"; 
            } 
            if (string.IsNullOrEmpty((txtStartDate.Text ?? string.Empty).Trim())) 
            { 
                txtStartDate.BackColor = System.Drawing.Color.Yellow; 
                lblError.Text += "Please enter start date! <br />"; 
            } 
            if (string.IsNullOrEmpty((txtEndDate.Text ?? string.Empty).Trim())) 
            { 
                txtEndDate.BackColor = System.Drawing.Color.Yellow; 
                lblError.Text += "Please enter end date! <br />"; 
            } 

            DateTime dt1; 
            DateTime dt2; 

            dt1 = DateTime.Parse(txtStartDate.Text); 
            dt2 = DateTime.Parse(txtEndDate.Text); 

            if (DateTime.Compare(dt1, dt2) > 0) 
            { 
                //Checking if the end date is greater than the start date 
                txtStartDate.BackColor = System.Drawing.Color.Yellow; 
                txtEndDate.BackColor = System.Drawing.Color.Yellow; 
                lblError.Text += "Start Date must not be greater than End Date! <br />"; 
            } 

            else 
            { 
                //output information if correct validation 
                Session["txtFirstName"] = txtFirstName.Text; 
                Session["txtLastName"] = txtLastName.Text; 
                Session["txtPayRate"] = txtPayRate.Text; 
                Session["txtStartDate"] = txtStartDate.Text; 
                Session["txtEndDate"] = txtEndDate.Text; 
                Server.Transfer("frmPersonalVerified.aspx"); 
            } 
        } 
        catch (Exception ex) 
        { 

        } 
    } 
}

I have a submit button that when pressed is supposed to input the above information into a text box on another page if it validates correctly. Right now it doesn’t do that.

Here is my code on frmPersonnalVerified:

public partial class frmPersonnelVerified : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
        //Inputs information from frmPersonnel and places it into the  
        //textbox called "txtVerifiedInfo" 
        txtVerifiedInfo.Text = Request["txtFirstName"] + 
            "\n" + Request["txtLastName"] + 
            "\n" + Request["txtPayRate"] + 
            "\n" + Request["txtStartDate"] + 
            "\n" + Request["txtEndDate"]; 

    } 

}

You’re storing the variables in Session but then trying to access them through the Request object. Change it to Session, and it should work:

public partial class frmPersonnelVerified : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
        //Inputs information from frmPersonnel and places it into the  
        //textbox called "txtVerifiedInfo" 
        txtVerifiedInfo.Text = Session["txtFirstName"] + 
            "\n" + Session["txtLastName"] + 
            "\n" + Session["txtPayRate"] + 
            "\n" + Session["txtStartDate"] + 
            "\n" + Session["txtEndDate"]; 

    } 

}

However, putting values into Session can be problematic so be cautious.
