He's returning a collection of entity objects. It's at least partially a religious discussion. I've seen all sorts of other OO principles thrown out in order to pursue this one goal. It's not clear cut, and you need to make a call based on the needs of your project.
It is very sexy to call the data layer and get back a list of custom business objects, tho.

Hi friends![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
In my asp.net form, I want receive an image from network and show it. The image has jpeg format and is sent in Byte[] format. When I receive it, how can I display the image? pleas write the code. 
thanks

your server needs to recieve the image, and either save it to the hard drive, or your page will need to show the image and nothing else, then you can do a binary write

Binary write to the Response. Set the Response content type to image.

You can pass the values from the first form to the second with cross page postback or on the URL, then have a button within the page which goes back and repopulates the old page.
The other way to do it, is to make both form controls that appear on the one form, then you will have viewstate between what appear to be pages.

You mean in single page and changing the visibility ? But browser will keep the posted data on cache and repost on hitting refresh. Are you familiar with Java beans ? I think that is something related to passing values between pages, but not sure

Well, I have a vague idea about beans, what I can say for sure, is they are not going to help the OP, who is using ASP.NET.

if u want to see the information u must session,viewstate to store the information......
i think it is not possible by setting a property .........
Have great programming....
|
|
|
|
|
But if the form has many controls and if i set autopostback is true,it doesnt look good for each control page will be postback.
But by using viewstate or session variables ,it is not good.
i dont have any idea of javabeans.
How to solve this problem.
Bcz forms are big in size(so many controls).
give me some other idea.

You only need to do a postback when you navigate to the next page. You can do a postback, store your values, and then move on, and then you can expect to be able to write code so when the page reloads, the values are restored.

That was a dumb idea, you're not using J2EE.

Those are your only options, unless you do some of the other things I suggested. At the end of the day, many web apps fail if uses click the back button instead of navigating within the site. If you offer a back button, you can control the behaviour, and then the two controls on one page idea is best, viewstate will do what you want, automatically.

You can use static property in the class.

There is an ASP.NET file selection control, that's what you need.

Use FileUpload Control. To get the file name use
if (FileUpload1.HasFile)
FileUpload1.PostedFile.FileName
