I've got a custom asp.net 2 login authentication creating a generic principal object and working great except that I can't get the logout to truly abandon/clear. For most of the site, I'm using one master page, but for the secure area, I'm using another master page. The secure master page uses menus, with the logout being a menu item redirect to another page (login.aspx?id=logout) with request parameters to fire. When I click logout, it does indeed take me back to the login page. But, if I manually type in the page where I've just been, it lets me through without a login. I've tried researching the problem and implementing suggestions to others, but nothing has worked. Any help GREATLY appreciated.

Hi,
Can anyone provide me the regular Expression for validating the Person Names. That expression need to handle all types of names in the best way. The name contain alphanumerics and some special characters like _ , . .I don’t know exactly about any other type of special characters in names.
Thnaks

Go download a tool called Expresso. It will help you create RegEx expressions. This tool has many common RegEx expressions included with it, you might get lucky and it is there. If not, this is the tool I use to create my RegEx expressions.
If that tool doesn't help, look up some of the RegEx articles on CodeProject.

I am depolying a website on several different machines that we are testing with. We are trying to use anonymous authentication for the site. This works just fine for all the machines except for 1 running Windows XP. On that machine, it always pops up the Connect To dialog box for anyone that accesses the website.
I check the settings for the website and it is set to anonymous as the other machines are.
Also, if running locally, it will not bring up the Connect To dialog box if the web address is localhost or 127.0.0.1.
I know it has something to do with the machine security settings, but I am not able to figure out what.
Can anyone tell me what other things I need to look at in the machine in order to allow access without the Connect To dialog box showing up?
Thanks,
David

Hi all,
I have implemented Nested Master page concept in my web portal(which has multiple website in it).
Explanation:
Parent (Master Page) - webportal level master page.
child (Master page) - website level master page.
child uses the parent master page and content pages are produced from child master page.(That how it is nested).
Issues are:
1. .css file can only once reference, that is in parent master page.
when I tried to reference another stylesheet in my child master page, it didn't work.
Consequences: The style is going to bulk. because it is going to be global for web portal(for all the website inside the portal). Globally all page's received byte will be increased due to bulk .css file (decreases the performance).
2.
.js file can only once reference, that is in parent master page.
when I tried to reference another .js file in my child master page, it didn't work.
<b>Consequences:</b> The .js file is going to bulk. because it is going to be global for web portal(for all the website inside the portal). Globally all page's received byte will be increased due to bulk .js file (decreases the performance).
<b>3.</b> Globally there is only one form on parent master page. I want to have one form in the child master page for posting values to out side asp application. (that is from website level not from web portal level).
<b>Consequences:</b> Posting globally from parent master page is going make the parent master bulk with all the hidden fields to be posted from various websites in the portal. Globally all page's received byte will be increased due to bulk parent master page file (decreases the performance).
Please let me know. Is there a way to get arround the above issues.
I would appreciate your ant kind of help on this.
Thanks
Mohamed

1a. You can create themes, and put whatever css files you want in them. When a page uses a theme, links to the css files will be added to the header.
1b. Link tags can be added to the header using code.
2a. Your script tag is wrong, which may explain part of your problems. The script tag must have an end tag, even if it doesn't contain any code.
2b. You can include scripts anywhere in the page. Even if it's recommended to include scripts from the header, it can be done anywhere. It is frequently used anywhere in the code, for statistics and advertisments for example.
2c. Script tags can be added to the header using code.
3a. If you choose to have the form in the master page, your pages will be limited by that. There is no need to put the form in the master page.
3b. A page can have any number of forms, as long as they are not nested. Forms can even be added when needed using Javascript.

Not at all. You can put css files in a theme, and those will of course affect all elements on the page, not only elements created by server controls.
Are you thinking about the use of skins in themes?
Md Arif wrote: 1.b Is it possible to refer 2 link(.css file) that is one in Parent master page another in child master page.I tried, it always refers to the parent level link(.css file).
If you add two link elements to the header, both will be used, regardless of where the code is that adds them.
Md Arif wrote: 2. Is it possible to refer 2 .js file in one website.if yes please let me know.

Yes, you can use any number of script files in a page.
How did you check if the files were included?

Read the 'how to ask questions' sticky post at the top of this forum. What you've been told is correct. Now, it remains to work out what you're doing wrong. 'It's not working' does not give us the info we need to work out your error.

Has anyone found any documentation on how to drag and drop between two list boxes? Preferrably with AJAX. Any help would be greatly appreciated.
Thanks,

Do you know what AJAX is ? You need javascript to do what you're describing, but unless you want to store what is in which listbox in your database as it occurs, AJAX is of no value to you whatsoever in doing this.

hi frns
i am developing webapplication in c#.net 2005
i want to display the count of records present in gridview of my application into textbox control can anybody suggest me to do this task.
regards
sunil

|

if you bind gridview with dataset then you can use
txtCount.Text=ds.Table[0].Rows.Count.ToString();
OR
after binding gridview you can also count gridview's rows
txtCount.Text=gv_List.Rows.Count.ToString();

The AutoPostBack property of your control is set to true, so after the selection it postbacks. Set it to false
