Hi rahul,

One way is to achieve the above requirement is

Store the value of FirstName, LastName & DateOfBirth in class variable say firstName, lastName & dateOfBirth and then Set the paramater for FirstName, LastName and DateofBirth again in contactinformation.aspx.cs file.

Response.Redirect("DisplayPage.aspx??FirstName=&LastName=&DateofBirth=&EmailId=&MobileNo="+ firstName+ lastName+ dateOfBirth+ txtEmailid.Text + txtMno.Text);

Hi Rahul,

I forget to update the below file as we don't require any public string declartion we can directly assign the value to label.

DisplayPage.aspx.cs
public partial class DisplayPage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        txtfname.Text = Request.QueryString["FirstName"];
        txtlname.Text = Request.QueryString["LastName"];
            txtdob.Text = Request.QueryString["DateofBirth"];
            txtEmaillabel.Text = Request.QueryString["EmailId"];
            txtPhoneLabel.Text= Request.QueryString["MobileNo"];
    }
}

Object reference not set to an instance of an object means somewhere the object is null and you are using that object in many places for operation. Put debugger and check where you are getting null and resolve that null value. Also check this video for an example, https://youtu.be/GwtevbSLuXQ
