Like IsPostBack property there is IsCrossPostBack property 
that sets to true if page is redirected from a page.

cros page posting is page to page data transfer machanism 
like query string. 

you can do it two ways : 

1. using <%@ PreviousPageType VirtualPath="~/
SourcePage.aspx" %> directive :- If the target page 
contains a PreviousPageType directive that points to the 
source page, you can access the source page's CurrentCity 
property using code such as the following.

Label1.Text = PreviousPage.CurrentCity;

2.  Using PostBackUrl and PreviousPage property :- 

In source page specify PostBAckUrl property to control 
which  you use to generate postback like, 

 <asp:Button 
  ID="Button1" 
  PostBackUrl="~/TargetPage.aspx"
  runat="server"
  Text="Submit" />

In TargetPage.aspx :- 

if (Page.PreviousPage != null)
{
    TextBox SourceTextBox = 
        (TextBox)Page.PreviousPage.FindControl("TextBox1");
    if (SourceTextBox != null)
    {
        Label1.Text = SourceTextBox.Text;
    }
}
