[bungpeng]

What do you mean original page? your current page? then you may try request.redirect or server.transfer

hi bungpeng

thx for replying

what i need to do is this

say i'm currently in a page called A.aspx in a href i'm calling a page called B.aspx

after doing some code there (in page B) i need to go back to the

page A.aspx

and i want the the data which exist earlier in the page A

i cannot use redirect fo rhtis cos page A contain query strings

[bungpeng]

Work like browser "Back" function?

using Javascript: history.back()

 

Is that what you want?

[dhj]

that is exactly what i want

but i cannot use javascript

is there a method to do this in C#

if so pls let me know

thx

[bungpeng]

You cannot use javascript? why?

Because C# is server site language and javascript is client site language, you cannot do this using server site language.

 

The advantage of javascript is it support by all type of browsers & it is free. I don't know why can't you use it...

Try a parameter with the return URL

 

I use the following code to update my main page when i update data in a popup-window:

 

Open the popup-window wiht a parameter:

....FilterPage.aspx?BaseURL="contact_tab.aspx&ID=xyz"....

 

Take care you have to replace the "&"

 

In the popUp:

...

sRet = Request.QueryString("baseURL")

....

 

To close the PopUp and reload to the original page:

(You can also define a link so that you don't have to do a postback)

....

RegisterClientScriptBlock("JS_Go", JavaScript.closePopUp(sret))

 

JavaScript.closePopUp is defined by me, because i don't like JavaScript (especially in my code) ;)

 

Here's the definition:

 

Const START_JS_TAG = "<script language='JavaScript'>"

Const END_JS_TAG = "</script>"

Const START_JS_LINK = "javaScript:"

Const END_JS_LINK = ""

 

Public Function closePopUp(Optional ByVal sBaseURL As String = Nothing, Optional ByVal AsLink As Boolean = False) As String

Dim tmpString As String

 

tmpString = IIf(AsLink, START_JS_LINK, START_JS_TAG)

If Not IsNothing(sBaseURL) Then

'Seite neu aufrufen

tmpString += "window.opener.location.href='" & sBaseURL & "';"

End If

tmpString += "window.close();"

tmpString += IIf(AsLink, END_JS_LINK, END_JS_TAG)

 

Return tmpString

End Function

i have been told to use only C# and not javascript

so is it possible to do this in C#

[skrampe]

yes it is

 

Yes!

 

The gist is:

 

Save the URL (querystring) somewhere you like it and where you can access it from "B" page.

 

In the "B" page you can read your URL (querystring) and do a

Server.transfer or whatever you want.

 

What i do: I'm saving the querysting into a querystring.

Sure, you can do it much easier.

[dhj]

thank you very much

i did it using querystrings

 

thx all

You could also save Page A's info in the Session Object, although if the number of data items is large, it could be a mess. You CAN create a class/DLL in C# and assign that class to the Session object. Check out this thread:

 

http://www.xtremedotnettalk.com/showthread.php?s=&threadid=81560

 

Then, you can just use Response.Redirect("PageA.aspx") to navigate without querystrings.

 

Basically, it would depend on the number of data items.

Sessions always become a mess, dispite the promises they seem to make. I recommend keeping the querystring method, and only using session variables for good reasons and only when you actually need them...
