View 5 RepliesWhat is the preferred way to retrieve large(approx: 50 MB) xml string from ASP.NET webpage?
Placing the xml string in file and downloading the file is not a choice.(This should be my last resort if nothing else works)
I have following method on ASP.NET server which is exposed through WCF service to silverlight client.
[code]...
Unfortunately these xml strings are approximately 50MB to 100 MB. Silverlight client needs to retrive these large strings and store it in a file on the client machine at the path selected by the user through saveFileDialog.
My concern is WCF service will not allow such large messages. How can I address this issue?

I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?
I'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?

View 4 RepliesSince 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.
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?
I am new to Entity frameworks-EF. As, EF is built on top of ADO.NET...If so, will there be any performance issue when we use it?Same way MVC also targets Test Driven , rapid application development only ..What speciality does it add for end-users?As per my understanding ASP.Net 2.0 itself is powerful without MVC and/or EF...

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.
