Hey!
I know it is a common question but I am too close and cant find solution. I have two Pages between A.aspx and B.aspx.

When you fill your name and surname on the textbox controls and then click on send button, redicted to B Page to say thank you for ordering but if you want to fill the form again for another ordering, click on back button from B Page to go back to previous page (A Page) and details (your name and surname) should remain on textbox controls. So you dont need to write your name and surname again. How to do this?


A.aspx:
<label>Name:</label> <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
<label>Surname:</label> <asp:TextBox ID="txtSurname" runat="server"></asp:TextBox>
 <asp:Button ID="Send" runat="server" Text="Send Email" onclick="Send_Click" />
A.aspx.cs (C#):
  protected void Send_Click(object sender, EventArgs e)
{
Response.Redirect("B.aspx");
}

B.aspx:
<p>Thank you for ordering. We will contact you very soon.</p>
<p>Do you want to order item again? Go back to A Page  <asp:Button ID="btnBack" runat="server" Text="BACK" onclick="Send_Click" />
</div>

B.aspx.cs (C#):
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write(Request.UrlReferrer.ToString());
    }
Problem: when i clicked on back button, redicted to A Page and all the details (name and surname) are gone from textbox control. I want these details to remain, dont need to write it again.
Your help will be highly appreciated. Thanks for your time :-)
