Answer / abhishek kumar

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;
}
}
