You can't.
You have to get the value in the server code, and either create Javascript code that recreates the value, or put it in a hidden field where the Javascript can access it.

You need to read it in the codeBehind to a protected variable like
protected string strAppTitle = ConfigurationSettings.AppSettings["AppTitle"];
Then in the JavaScript, you can use
var strAppTitle = "<%=strAppTitle%>" ;

Use AJAX to call a server function for getting the values from web.config

What database you using? I think you can alter the table structure with the stored procedure or you can you temporary tables. But with my little experience I believe that it is not a good practice to change table structure in runtime.

To create a table in runtime uses a stored procedure. But I wondered why you create a new table for each user? Suppose if 1000 users registered in your system, your database will have 1000 tables!!!!!!!!!!!!!!!!!!!!!!!!

yes it may be bad idea, is there any idea you know how to maintain a database in case of web mail server like yahoo on any sidev link where related stuff can be find
thanx forv reply

You can dynamically create table using same query as we use in creating a table in MS SQL (CREATE TABLE). But creating table for each user is a bad idea...
|
|
|
|
|
yes it may be bad idea , do you know any other idea of maintaining data in web mail server like yahoo, orkut or any site link
thanx for replying
prashant jain malviya national institute of technology

You can maintain the data in normalized database. Say, User's information will be in a Table, All the messages of the users will be in another table with a reference and so on. If you are not so good at Database, then try XML. But Database is best way.

thanx for replying . is the database in yahoo mail etc , is maintain in same manner . is it effective to store the complete mail as a string in the table .do you have any website site link descussing on this topic.

Hi friends,
I have a page with a dataview binded to a datatable. I want to delete all the rows with a checkbox marked on it.
The problem is that in the button's OnClick event the DataSource property of the DataView is NULL. I cant have access to it in order to know the IDs of the marked rows.
How can I do this?
Thanks averyone

You need to cache the datatable because in every post back the datatable will be cleared.
Thomas

|
|
|
|
In which event you are binding the DataView?
|
|
|
|
|
just declare your DataTable as static , and get data in DataTable like..
public Static DataTable dt = new DataTable();
if(!IsPostBack)
{
dt = //some binding code...
}
now you will not lost data from datatable..
bye have a nice day.

-->We been doing our first website,"Security Web Control" like "Log In" "login view" are the most commonly used in asp.net.
if our security web control composed only on a html control,what will be the difference?we were not able to set up a Membership role and profile in ASP.NET Website Administration Tool ?becuase we manually make our original "Security web control"..
-->and why always aspnetdb.ndf is always a default database?
what if we make our database using MS Access?can we access it or make it a default website in a ASP.NET Website Administration Tool?now can it b done?
what are the alternatives way to used if im not going to used a ASP.NET Website Administration Tool? to set up membership?...
-->When im modifying a connectiom of the database(in a database explorer In Visual Web Develper)?im only used the Microsoft Access Database File (OLE DB) native Jet Provider and Microsoft SQL Server Database File (SqlClient)-(a mircosoft Server Instance including MS SQL express)..but in other provider,the "servername" always ask, and when i type the server name,im only got error like when i modified connection MS SQL Server(Connect to Microsoft SQL Server 2000 and 2005)...
Im always modified the server name in the SEt Up Wizard using aspne_regsql but i always got err0r..
Hope all my question can clearly answred
Thanks for always helping....

I did this a long time ago and don't remember what I used so I'm hoping someone here will have an idea.
I used a data structure in a function that took a string parameter that I passed in. A data structure in that function would insert the string if it didn't already exist and it would raise an error if it did. That way I could easily tell if I was working with a repeated string value in a series of data related events.
I am having total brainlock and don't remember what I used... Anybody got an idea?...?

Really annoying me now cos I have seen this so many times in my project and am yet to work out exactly why it wont work. I have about 10 textboxes all with validation controls. Some with two.
For some reason the page goes nuts in IE 6. Firefox displays it exactly as expected. When you press the submit button it changes the page again and different elements go nuts.
I have been through my CSS, checked all code from the browser and the rest but still no obvious reason for it. If I remove some of the validation controls it stops happening but there is no pattern to it.
Any body seen this before?
One more thing. IE 6 is a piece of sh*t!!

Try to find any alternate solutions. Have you tried JavaScript for validation? I feel it is flexible than validation controls
