Why we use Web.Config File for connection string wether we can use class Library for get connection for whole web Application please help me?
Friend, Web.config has its own advantages.
1) Web.Config is used to store the important information like connections strings etc...so that it can be modified even after the code has been deployed to the server without compiling the entire application again.
2) Since it is a XML file, there is no need of building the project of you are going to change the connection strings.
If you go for the class files,...OLEDB Connection problem using Connect String from Web.config

M....How do I use my web.config connection string in my DataAdapter/Connection that I created with drag/drop and data binding
This is a little hard to put into words...
I have a form with a number of textbox fields on it that are bound to a data adapter.

...How to use the connection string from the web.config with a method?
I have been trying to create the connection and then pass it around with no luck. Instead I've been able to just keep recreating it with each method on the page. I don't know why when I create a variable in the page_load event it just doesn't get seen inside of methods. If I put the variable holding the connection string in the page before the page_load event, I think the page class?, it still doesn't work. Could someone give me a heads up on why please?

Im using membership in my application, but I dont want to define the connection string in the config file also. I want to store itelsewhere, then when the app starts up, load it and set this value.

Will this work ?
