Thanks, I was under the impression that the web.config replaced the global.asa

Well... if It's in the onload of the master page, that means it will be among the very first lines of code executed in your application. Thus, it will be checking for the session variable, in all likelyhood, before you can get the chance to set it.

This is not really accurate (not trying to offend anyone).

If you use a master page (with a content page obviously) the order of events (I might miss one) are as follows.

Keys:
C = content page
M = master page

1) Pre_init (C)
2) Page_init (M)
3) Page_init (C)
4) Page_init_complete (C)
5) Page_load (C)
6) Page_load (M)
7) Page_PreRender (M)

Part of the reason for the events taking place like this is it gives you the flexibility of manipulating "something" on the master page based of "something" on the content page.

Just thought someone might find this usefull.

Dockable window in asp.net

24-Jul-07 4:59

I take it that you received a NullReferenceException?

I had the same issue, my problem was that the Session("X") did not have a value before I tried to access it.

Re: events are not firing.

You have access to the opener in the popup window, so you can use that to set fields in the main window. In javascript it would look something like:
self.opener.document.forms[0].controlnamehere.value = "whatever value";

Hope that helps.

Can anyone tell me the reason please..
I am in great trouble since many hours

hello chauhan,
Events will not fire since u have changed the body.Take a fresh form and copy the application or do again the same application.This happens due to Page faults or Intialization or problems in page life cycle.

ok byee

You'll need to ask that on a PHP forum - this is for ASP.Net.

Here's a good place to get started: http://www.php.net/[^]

I wouldn't advise any - sessionstate shouod only be used to store SMALL amounts on information, such as user ID and maybe their name, or flags to indicate user-preferences on your site. If you start storing datasets and the like in there, you will seriously limit the scalability of your application.

Huh?

I can't figure out what your question is. I can tell you that 'Session' is a place you can store an Object. DataSet, HashTable and DataDictionary are all data structures that could be stored in Session.

Use images directory in the root

JacquesDP24-Jul-07 1:59

Hi all,

How do I specify to use the images folder in the root directory?

I have a master page that is in the root of the website, and the content pages are in subfolders with one index page that is also lying in the root.

So when I open the index page in the root, all the images on the masterpage displays, but when I go to on of the other content pages within the subfolders, the images on the masterpage does not display, I dont want to copy the images folder into every subfolder that may contain a content page.

In your path are you using ~/images/img1.gif? The ~ goes to the root no matter where you are.

Hope that helps.

Not working, that even stops the masterpage from displaying the images when I am in the root index page

here is what I am using in the masterpage

that works but as soon as I enter one of the pages in a subdirectory the masterpage no longer displays the images,

when I changed it to

then the index page in root stops the masterpage from displaying the images.

I thought that because the masterpage is residing in the root of the app, it will not have an impact on where the content page is.

Switch your <img to a <ASP:Image runat="server" and then the ~ will work. The ~ only works for asp.net server controls not html controls.

Hope that helps.
Ben

JacquesDP24-Jul-07 2:27

24-Jul-07 2:27

Thanks, That works, if the path is entered, what I want to do now is load the paths from the database, then on server side I have an image variable which will contain the path.

But when I enter the following
(asp:Image runat="server" ImageUrl="<%=ImageURL%>" Alernatetext="" /)

then I have the problem that because the asp image is server side, I can't pass the ImageURL parameter,

Slowly I'm going to get there....

Changed the < with (, otherwise it doesn't display
