A partial class is normal class only. Using the partial keyword we can separate the code in different files. When it is compiled, it will be compiled as a single class. I didn't understood what do you mean by globally accessible ? You can set this class object to session which is accessible on all pages.

Other webform ? This won't be possible as you did, you need to pass the class instance through session or any other medium.

Is it possible to have a complete webpart along with its close and minimize button in an updatepanel. so if we minimize it or close it then just it could get refreshed not the whole zone it is placed in, which is the current scenerio.

I have currently placed the whole zone in the update panel.

I am also including a link of the site where you can see what i want ...

How you declared this ? in Global.asax ? I don't think it's a good solution and in which scenarion you require this ?

How you are going from one page to other ? Using a Response.Redirect() ? then set the value just before this line. There is no event fired when you move from one page to other using normal hyperlinks. You need to hook a javascript function on body unload event and using an AJAX call set the variable value to false.

ps.srinivasan wrote:

Yes, when page requests, it will load the page and call unload. See the ASP.NET page lifecycle.

Hope you are speaking about web applications only ! AFAIK, there are not much efficient methods to satisfy this. You can make use of application variables/a database flag indicates somebody opened the page. But big question is how you will reset the value when he finished his visit ? You should rely on some sort of javascript which works on unload. But what will happen if JS is disabled on client's machine ? Your flag status will be still active which prevents further users to the page. So it's not a good solution. Why do you need to implement this ?

If you are planning to implement any of the methods I suggested above, make sure you have a time-out mechanism which updates the flag/application variable to the initial stage.

How are you maintaining a global variable ? Do you think that's a good idea ? What if two people are using your site and one is one form1, and one is on form2 ? What are you trying to achieve ?

Don't declare the global variable.. You should use "Session" or "Cache".

For example:

Assign "True" to session in WebForm1.

<br />
Session["myvalue"] = "True"

Set "False" this in Webform2.

Session["myvalue"] = "False"

You should write this in From_load of Webform2.
hope it helps.

It would be better if referrer also checked to ensure it comes from webform1. Else if anyone directly took webform2, value will be set to false.

This is a bizarre requirement for a web app. Your problem is, you cannot know if the first person has left the page. The best way to handle this is to store what pages are 'in use' in the database, because you also need to store the time/date they became in use, and impliment a timeout so that the user loses the page after a while. Otherwise, I can browse to your site ( and I assume I'd be one of only 2-3 people worldwide doing so, for your requirement to not make the site useless ), turn off my PC and your site is broken.

I would like to add a few things that might work for you...

I think that Session State is based on the user, right?

- As Christ said, you should store the pageid and status "in use" in the database.
- If you move to other page then change the pageid.
- Check whether a particular page is in-use or not in every page_load.
- Use "Session" in your page. (you wanna say that you have nothing to store in the Session variable? anyway, use it.. otherwise, you won't get "Session_End".. )
- Delete the record ("pageid" and "in use") in Session_End event.
- Don't forget to set "Inproc" in web.config..

I think that it might work.. but it is better if you can change your requirement..

hello friends,

I am using paypal controls in my project and i am having two problems which i don't think it is solvable by coding.

the first problem is:

when after clicking on "Buy Now" button of paypal my IE blocks the cookies of the paypal site.when i unblock the site cookies it works fine but for this i am using the Internet option->privacy->unblock the sites.....

but what i want is that any way to solve this problem in asp.net..................

The second problem is:

when paypal site open, it open in a child frame.After completing the transaction process, when i click another link of my parent frame then it shows in the new frame which is not allowed so what i think is to open the paypal site in new window.

so is there any property of "Buy Now" button which open paypal into the new window........

if you have any way to solve this problem, then please reply me. on mail or on forums....

help will be highly appreciable.......

thanks in advance....

bye...

If the subjects are coming from a table, the most likely way to render this is with a repeater.
