Friends,
I am just a beginner and I have some doubts with web.config file.
It would be helpful to me if anyone come up with answers for these questions.
1. When a web.config file is called in a .net web application?
2. Is it possible to have more than one web.config file for an applicaiton?
3. What is the concept behind declaring the connection string in web.config file?
4. What is the difference between app.config and web.config files?

web.config is used with web applications. web.config will by default have several configurations required for the web application. You can have separate web.config files for each directory in your web application, in addition to the one in the root. For each web page, by default, system will look for a web.config in the same folder as the page and if not found, then looks in the parent folder.
app.config is used for windows applications. When you build the application in vs.net,i think it is same as web.config but not sure...
declaring a connection string in the web.config file is as to declare connection strring once and use in different webforms otherwise in each webform we have to declare connection string which is redundant.the string can be retrieved as follows
System.Configuration.COnfigurationSettings.AppSettings["Key"]

Thanks for your reply Kousik.
But when this web.config file is called?
Is it that, each time when a user request for a page, the web.config file is called?
Or, is it like, web.config is called only when we try accesing the variable/key declared and stored in web.config?

HI Friend
Asked a meaning full question
Saranya B wrote: 1. When a web.config file is called in a .net web application?
At run time (When Application runs) common language runtime reads (such as assembly binding policy, remoting objects, and so on), and settings that the application can read.
Saranya B wrote: 2. Is it possible to have more than one web.config file for an applicaiton?
Yes , Web.config files can appear in multiple directories in ASP.NET applications.
Saranya B wrote: 3. What is the concept behind declaring the connection string in web.config file?
Security and Consistent Suppose if the connection string has changed then i need to change it only once i.e. in the web.config other wise i have to check each and every page and update it.
Saranya B wrote: 4. What is the difference between app.config and web.config files?
app.config is used for windows applications. When you build the application in vs.net, it will be automatically renamed to <appname>.exe.config and this file has to be delivered along with your application.
If you make any changes to the web.config, web application will immediately load the changed config. But in case of <application name="">.exe.config, you have to restart the application.

In my point of view you can't, Because ASP.NET is server side scripting language. Whatever you are seeing on the page is the processed output of ASPX page. So you can't handle clipboard using ASP.NET.

|

But I think it can done by JavaScript. I didn’t check it. So try the javascript object “clipboardData”

Hello,
I have webpage1 that has a dropdown list contains Department list. When I click submit, in my second webpage, the dropdownlist must contain the names of the Department selected in the webpage1.
Anybody can show me the simple code for this one. Thanks in advance.

|
|
|
|
You can send the selected item value to the second page through querystring and then can access that in second page and set the selected item.

Or...
you can configure the PostBackUrl property of a ASP.NET Link Button. Then, within the other page code, you can access Page.PreviousPage. It'll give you access to the members of the previous page (the one that contains the link button), like the selected Item you want. I think this aproach is even better because it keeps your URL clean.

Hi everybody...
Does anybody know if it`s possible do register some javascript code in a control`s parent page, especially inside a head tag? These javascripts need to access and interact with some Html Controls inside the control. Is it possible? I don`t want to post back my page so I do prefer to interact with users just using DHTML and Javascript.
Thanks in advance...
Cheers!!! XD
