hi Ravi
every page in asp.net is a class. so from Page 2, you can use the following
code:

dim myPage1 as new Page1()
myPage1.FunctionWhatever()

you must understand though that you would just be creating a page object
with a scope/lifetime limited to the current block of code you are in (e.g.
Page2.button_ok_click).

what you should really do in your situation is organise your code better.
if you have shared code that is needed by Page1 and Page2 then it should be
in a class of its own. if you're using .Net2, just put a new class file
into App_Code which is the shared code folder. otherwise just insert a new
class anywhere in the application, then it can be used by any page in your
site, without having to go creating Page objects just to use the code
contained in them. the code i've written above is a really poor way of
sharing code between pages, unless it is absolutely necessary, and even then
i can't think of a good reason why you would want to do this. just suppose
that later on in the development of your site, you decide to delete Page1,
but ooops you forgot you had code in there that Page2 is dependent on, so
you break the site and have to pull out the code.

a page should be encapsulated, without having dependencies on other pages.
otherwise you will end up with a monster of a web site with so many
inter-dependencies between pages that it will be very difficult to maintain.

Yup... here is the code.


VB or C#?

I put C# version here.

btnSave is the ID of ur Parent save button
In the aspx of the child page (head), put this

  <script type ="text/javascript" language="javascript" > 
function callParentClick() {
       window.opener.document.getElementById('<%=btnSave.ClientID%>').click();
      }
</script>

------------------------

In the button click event of the close button(code behind .cs file) put this

 ClientScript.RegisterStartupScript(this.GetType(), "CallParent", "callParentClick();", true);

Open in new window

Does your popup is called from server side? If yes you dont need to call  savedata Button event. You should store all data in the session and then read it on the popup CloseButton click.
//parent page
private void SavedataButton_OnClick()
{
   Session["Data"] = ....
}

//popup page

private void CloseButton_OnClick()
{
   object data = Session["Data"];
}

Open in new window
