When you are redirecting one web page to another, you are passing values stored in variables, so 4 ways you can do that

1) Session Variable Previous page/Viewstate Variable

2)QueryString http://mysite.com/currentpage?from=previousPage

3)Using Property of a class eg. By setting Property set while redirecting and get while printing.

Here is another way.

Try it

public string GetCurrentPageName()
{
    string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
    System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath);
    string sRet = oInfo.Name;
    return sRet;
}


public string GetPreviousPageName()
{
    string sPath = Page.PreviousPage.Request.Url.AbsolutePath;
    System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath);
    string sRet = oInfo.Name;
    return sRet;
}

If you want Previouspage title then you can try this :

string PPagetitle= this.Page.PreviousPage.Title;

Or you can do little bit Javascript like this :

<asp:button id="m_BackButton" runat="server" onclientclick="goBack()" />

<script type="text/javascript">
   function goBack()
   {
       history.go(-1);
   }
</script>

Explanation of 3rd one : While moving from one web page to another you can pass data through class properties - but it works for Server.Transfer() only and destination page you need to define

<%@ PreviousPageType VirtualPath="~/SourcePage.aspx" %>

.Here is the demo

// Source page

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

but in your question, you have asked that you are moving from one .aspx page to another .aspx page. As per your question this answer is. Please modify your question or post a new question. — Chandan Kumar, Nov 02 '13 at 08:12
