You can use a Compare Validator.Please check Type and Operator Properties.
Otherwise you can use a CustomValidator.

Hello,
I have a web application hosted on local machine. Ex: http://localhost/xyz.aspx
We have login page which prompts for user id and password. Once the user is validated, enters into another page. On all other pages, the user name gets displayed.
Can we determine is there any session for the website is running or not? if we can find it, we want to stop multiple users from logging in from the same system.
Please give me any ideas on this.
Thank you,
Raheem MA

You're going about it wrong. Store a list of logged in users on the application level and check it when a user tries to log in. Add a time stamp for the last access, so you can time out users who didn't explicityl log out.

Thank you all for quick response,
The website is already in production. The user name gets displayed on all the pages once the login successful.
Suppose user A logged in and USER A is getting displayed on the next page.
In another browser window user B logged in and USER B is getting displayed on the next page.
Now, if you go th browser A, and do refresh the page, then USER B will be displayed on the page. this is the issue currently we have.
How to overcome this? Please give me ideas 
Thank you,
Raheem MA

You have been given two ideas. Obviously, if you've released the product, you are going to have to change it to overcome this bug.

Hi Raheem,
You can try like this....
If you are validating user login against database then add one more field 'status' in ur table and update this field for successful login.
In this way if another user tries to login then you can check status field , if it is not updated allow login otherwise inform that this login is already in use.,
And dont forget to update status field when user logs out.
Note: you need to explicitly update status field in session_end event and in page unload events.
Hope this helps you.
Happy coding
Regards
Surender M

EVen this cannot be trusted, he needs to add a timeout, and store the time of each page request, so he can tell that enough time has passed to regard the user as logged out

Can i fill the gridview from different tables in same database? How can i do that? Can i use join statement?
|
|
|
|
|
Yes,you can.Customize your data retrieval query as per your requirements and fill it to a entity list that u have created.
|
|
|
|
|
yes you can do this. when you add database source for Gridview just select
1. Specify custom SQL statement or store procedure
2. on the next step you found a query builder button just click it and add table as as you want
in this way you can add many table according to your requirement
|
|
|
|
|
I tried that. But it will join the table, but it will use join statement which will do using Cross join. Using this it will repeat the values for corresponding other values. It will not solve my problem.
|
|
|
|
|
write me your complete problem. what r your tables to whom you want to access in gridview.
thanks

We need to build a component builder from which we can drag and drop the components like button, textbox, label, listbox at runtime in .net. Kindly help . TIA

Don't double post ? You need for clients to be able to drag and drop UI and create pages ? You have a ton of work in front of you then. I'd expect you'd want an activeX control to do this, not to try to do it in JS.

Could anyone give us some inputs on how to dynamically generate an aspx page and its CS page using XML and XSTL .TIA
|
|

I am not sure that you can, because once you do, how do you pass it to the ASP.NET engine to generate a page lifecycle ?

Well, it seems you don't put quotes around the text you're emitting. Beyond that, why you'd do a postback and then run a js function, what it does, and what you mean by 'problem' ( that is, what happens, and what you expect to happen ) are mysteries, so it's impossible to offer more help.

Do you have AJAX ScriptManager in your page ?
|
|
|
|

Why would he have to ? Nothing in his post has anything to do with AJAX.

No, I have just asked because if there is ScriptManager on his page, then he can try with ScriptManager.RegisterStartupScript().
