What are some of the advantages of using one over the other?
I hate webform that no matter what action is done with a client side page(such as clicking a dropdownlist to only see the Items), it cause a postback&re-rendering of the whole page and all of the page events is raised( page_init,page_load....complete....).
We know that the server side .cs page shoudnt have to go through all the events and many methods(such as "IsPostback",viewstate), in fact,it just have to do only one thing:get data from DB for the dropdownlist and show it to us, other part of the page just doesnt have to change.
We may achieve this effect using Ajax, but the key is I dont wanna raise too many useless event .
seems MVC can handle such a problem, one action of browser side is replied by exactly one method,and time isnot waste by raise event...
Is this the biggest advantage of MVC?
Since Themes in ASP.NET are used to style elements of your site, I was just wondering why would you use Themes rather than CSS, or is it common practice to use both? If so, when would you opt for one versus the other and why?
Just seems to me like Themes are kind of unnecessary, so I am just looking on clarification if there really is a good reason to use them, or it's just a part of the framework as an alternative(unnecessary) step to styling your site.

View 1 RepliesI have to write a stored procedure to get the biggest two values out of three in three different columns in the same table.
I have a table , for instance,
total marks1 - column1 ( eg values - 1000)
total marks2 - column 2 (eg values - 500)
total marks3 - column 3 (eg values - 800)
i have to get (return the value) 1000 and 800.
I've gone rounds with this ever since I started programming classic ASP 12 (or so) years ago and I've never found a great solution because the architecture of ASP and ASP.NET has always been a swamp of bad practices, magic shared singletons, etc. My biggest issue is with the HttpApplication object with its non-event events (Application_Start, Application_End, etc.).
If you want to do stuff once for the entire lifespan of an HTTP application, Application_Start is the obvious place to do it. Right? Not exactly. Firstly, this is not an event per se, it's a magic naming convention that, when followed, causes the method to be called once per AppDomain created by IIS.
Besides magic naming conventions being a horrible practice, I've started to think it might be a reason there exist no such thing as a Start event on the HttpApplication object. So I've experimented with events that do exist, such as Init. Well, this isn't really an event either, it's an overridable method, which is the next best thing.
It seems that the Init() method is called for every instantiation of an HttpApplication object, which happens a lot more than once per AppDomain. This means that I might as just put my startup logic inside the HttpApplication object's constructor.
Now my question is, why shouldn't I put my startup logic in the constructor? Why does even Init() exist and do I need to care about Application_Start? If I do, can anyone explain why there is no proper event or overridable method for this pseudo-event in the HttpApplication object?
And can anyone explain to me why in a typical ASP.NET application, 8 instances of my HttpApplication are created (which causes the constructor and Init to run just as many times, of course; this can be mitigated with locking and a shared static boolean called initialized) when my application only has a single AppDomain?
i have i doubt. any body clarify this doubts. Find biggest character in a string. using ascii values.

View 1 RepliesI'm now getting into EF and from what I'm seeing so far, I wouldn't have to worry about writing stored procedures any more. Looks like EF takes care of all of that -- including INSERT's that store data in multiple tables. One of the things they taught us when learning stored procedures was that they're compiled which has performance benefits. How does EF 4 fare against using stored procedures?

I am not able to add the service using Add Service Reference. I am not able to get the WSDL using a browser.

Then, What's the specific use of Mex Endpoint.

routes.MapPageRoute(

When i started developing web applications i stored the authentication details of the user in two session variables
Session["UserName"]="username";
Session["Password"]="paswword-123";
But someone proposed me an idea to create a class which holds the UserName and Password properties and on succesful authentication i have been asked to create an instance of the class and set the UserName and Password properties and store that instance in the session.
I have been told that the session object is TypeSafe. Can someone explain what is typesafe coding and the advantage of storing the object in the session.

I am developing web-app in .NET for 5 months (and enjoying it =)) and I am reading 3 books, all of them teachs at least 2 methods for acessing data: ADO.NET and SqlDataSource object.
I am used to work with ADO.NET method because I feel that even if it needs coding by hand, I can separate the SQL routines from the page and I can customize database routines better.
For now I am using DataReader mode because the application and the database is on the same server and there is only 1Gb RAM available so there is no advantage using DataSet on this moment.
Am I thinking this right? There are some things with SqlDataSource that I don't know how to do it well...
For example:
I have a routine that inserts a record on a table then gets the ID of this record using SCOPE_IDENTITY() function of SQL Server, than it uses this ID to insert another record on another table. Because I use a one-to-many relationship on multiple tables...
How can I work this situation using SqlDataSource object, is it even possible?

when i put the To email to be an Gmail,yahoo, hotmail email "as in example" or another domain.com email, the code is working with no issue, but when i put the recepient email to be any of Google Apps Emails, unfortunately the email didnot received. does the SmtpClient have a problem with google apps?
I have a dynamically-generated textbox and a static text box. They both have enableViewState = false. On the web page, I enter "ABC" in both textboxes. In the code-behind I set both text boxes to "EFG" in the page_load event.
In debug in page_load I can see both textboxes say "EFG". This is what I want.
When I hit the LoadComplete event, the STATIC textbox still has "EFG", but the dynamically generated textbox has gone back to "ABC".
I went one-by-one through all properties on the dynamically generated/static textbox, and they are all identical.
