Sorry couldn't help. My View State side of things is a bit bad, so can't really help you.
Good luck though. Maybe when you done you could post it here how you accomplished it.

Web Page Expiry Problem.

Hi,

I have webform 'Form1.aspx' in that i have placed a some textbox controls ,some labels and fileupload control. Finally some buttons : btn_Upload, btn_Show etc.

I used ajax update panel to upload a file(btn_UploadClick()).

In btn_ShowClick() i am transefering page to 'Form2.aspx'
by Response.Redirect("Form2.aspx?path="+uploadfilepathhere, false);

In Form2.aspx i have a image control and a LinkButton 'Back'. I set property PostBackClientUrl : javascript:history.go(-1)

In Image Control i am showing uploaded image to user .

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

i entered some text in textboxes, and uoloaded a file.

When i Click on btn_Show. the page is transefered to Form2.aspx, there the uploaded image is shown. Untill here every thing is fine.

But when Click on Back_LinkButton, i could not able to see the Form1.aspx.

It Displaying message like : Web page has expired.

Most likely cause:
The local copy of this webpage is out of date, and the website requires that you download it again.

But when click on refresh of browser ,i could see the Form1.aspx with all values which i entered previously here.

How to solve this page expiry problem.

please suggest me.

thanks in advance.

Why not just have is the PostBackClientUrl : "~/Form1.aspx" thats if Form1 is in the same Dir.
This will PostBack to the Form1 and Load the page.
Please try not to Name Your Pages Form1/2.aspx, try give them a meaningfull name.
Its always best to start good programming practices early on.

Hope this helps.

Hi Bardy,

Thanks for your suggestion. But i can't use this, because it i have keep old values which i entered in Form1.aspx as it is.

If i use PostBackClientUrl : "~/Form1.aspx", then i can see the Form1.aspx, but i can't see the previously entered values.

Is there any other way ...

Then why can't you do this on one page.
It would make you life a lot easier.
Just dump the contents that is in Form2.aspx into a panel in Form1.
Set Visible to fasle and once the button has been clicked just make it Visible.
Will save you a lot of trouble. The only other way is if you store all the values in Session variables.

Hi Bardy.

I tried that in Panel as you told.

But when i click on button, i am getting Runtime JavaScript errors like

Microsoft JScript runtime error: Object required

Microsoft JScript runtime error: Sys.ArgumentNullException: Value cannot be null.
Parameter name: element

Could you please paste some of your code so I could see.
You can take the Response.Redirect out of the button event.

Hi,

Here is my sample code:

I Placed a ImageControl, btn_PnlClose. design into Panel 'PNL'.set Visibility : False
I used update panel to upload a file using fileupload control.

Form1.aspx:
pageLoad()
{
//
}
btn_UploadClick() //Here i used update panel
{
//Uploading a file
//Adding uploaded file into ListBox
}
btn_ShowClick()
{
imge1.ImageUrl = "uplode file url here";
PNL.Visible = true;
}
btn_PnlClose_Click()
{
PNL.Visible = false;
}
////////////////////////////////////
When i build this, its successful.
But when i run this, When i click on btn_Show i got javascript runtime errors as posted in previous reply.

This seems weird because I have a page on my application which uses an update panel. The update panel contains a grdiview and a user can click on a row in the gridview to go to another page. On the other page I put a back button with the same code as yours and it went back fin, or be it with the page being reset.Can you explain anymore about your problem like what code is runnign on the first page

Hi,

I used update panel to upload a file using fileupload control.

Form1.aspx:
pageLoad()
{
//
}
btn_UploadClick() //Here i used update panel
{
//Uploading a file
//Adding uploaded file into ListBox
}
btn_ShowClick()
{
// taking path of uploaded file sending that in a query string to Form2.aspx
Response.Redirect("form2.aspx?path="+uploadedpathhere,false);
}

In Form2.aspx:
PageLoad()
{
if(!Page.IsPostBack)
{
image1.ImageUrl = Request.QueryString["uploadedpathhere"].ToString();
//Its working fine
}
}

I set Property 'PostBackUrl' of LinkButton 'Back' : javascript:history.go(-1)

When user clicks on Back button, I can see the URL 'form1.aspx' but the Page is not displayed.
It displays message : The webpage has expired.

But when i refresh browser, i can see the page with old values.

But it not happens when i hit on back button.
