Dear All,

I am using tiff images in my Application. When I select the page 2 of an image and click some button which has autopostback property, again page 1(initial page of the image) will be displayed automatically. I actually want whichever page of the image I select and click any button, that page only should remain constant.
I have been referring to the following links from past 2 days, but not getting any idea.

www.alternatiff.com/scripting/[^]

www.alternatiff.com/technical.html[^]

http://www.alternatiff.com/scripting/demo.html[^]

Please any one suggest or gimme an idea on this issue.....

Regards,

Raj, I receive you call for help from a different page and would need clarification:
1) How all this is related to TIFF?
2) Do you use TIFF on client side? (Posting TIFF is fine, but do you deliver tiff to the client, like in IMG element?
3) Generally clarify your goal. If you want the same page on postback, do you mean same URL but different contents? What do you mean "page... remain constant" and what should change on click".

I cannot guarantee the answer, but let's try...

sorry for the delay SA.. Actually, I am using tiff images in my solution with help of alternatiff plug ins.. The issue is that, when I select the page 1(initial page) of a particular image and click on a button with autopostback property, which calls the image using script manager... it works fine. But, if I select page 2 and click on the same button, again the page 1 is getting displayed. Hope, u have understood the problem.

Solution 1

I did used this long back to load scanned documents in web page...
You can you make a property as viewstate object type in your code behing that holds your tiff page no. and reloads it every time on postback...

I can try this. but can u plz gimme an example?

saxenaabhi6 12-May-11 2:51am

put this on your code behind


  protected int CurrentPageNo
  {
    get
    {
      object value = ViewState["CurrentPageNo"];
      return value == null ? 1 : (int)value;
    }
    set { ViewState["CurrentPageNo"] = value; }
  }

on your button click event on page 2, set the CurrentPageNo = 2
and in your aspx page you can do this in javascript


tiff0.GoToPage(<%= CurrentPageNo %>)

i think this should set your tiff page to page no stored in viewstate
see if that works

I have copied the property in code behind and set the CurrentPageNo = 2 in button click event. But, what the next statement does? i.e.,tiff0.GoToPage(<%= CurrentPageNo %>). where to call this??

did you install the active-x plugin of alternate tiff in your browser.

the next line set the 'tiff0' to page 2 which is the id of the active-x object you placed in the web page.
