It knows to scaffold that because there IS a link between category and product - it is defined in the model.
You will want to look into Navigation Properties in Entity Framework, the association is based on a few things:
The Product model has a foreign key link to category via the CategoryID property, so subsequently the product can only hold one category entry. In simple terms, a product can only be linked to one category.
The category model has a navigation property defined as:
public virtual ICollection<Product> Products {get; set}
This means that a category can have multiple products associated with it, which it is why it is defined as a collection in the navigation property as there are more than one.
I'd highly suggest having a read of this : https://www.asp.net/mvc/overview/getting-started/getting-started-with-ef-using-mvc/creating-an-entity-framework-data-model-for-an-asp-net-mvc-application[^]

Good day friends! Please I need your help. Am using asp.net in my web design where users can send message to other registered users. Am able to get it work but I want the process whereby some can enter more than one email address by separating them with comma.

i was using jquery datatable in webforms but data was more than 3000 records, client's browser gets stuck everytime. i used datagridview. but it is not good in performance.
now i want to use again jquery datatable using MVC 5. please suggest me ,whether it will be useful or not. becuase in MVC razor engine returns the whole HTML to clients browser. there is no processing at client end in mvc.
would appreciate if anyone answer me as soon as possible.
Thanks in advance.

Hi,
I hope you have implemented paging. If yes, you can send just 1 page of data in a request from the server.
Most of the client side tools are fast enough to handle 3000 records. I think the problem is not with jquery datatable. You might need to refactor your code.
Life is a computer program and everyone is the programmer of his own life.

i dont want to use paging in gridview.
i need all data on one page.
plz suggest me ,jquery datatable in mvc will be better approach or not. because i do not want to waste my time.

If you don't want to use pagination then don't show all data at a time. use scroll paging as user will scroll down and data will be loaded.
|

Why do you need 3000 items on one page? If it takes me 5 seconds to process each row it would take me 4 hours to do the page. What you'll probably need is something that loads the data on the fly with ajax, maybe implement it with an infinite scroll solution so that new records are only loaded when the user scrolls down. However, as people have been hinting at, your real solution is to redesign the page so that you don't need to show 3000 records.

You are right at all. but our client requirement is very different. he needs all data on one page, he dont want to wait on scroll down of page(he didnt like ajax call data on scroll,i did it once.)
I used jquery datatable for quick filter data on client side. but his browser gets stuck.then i moved changes to gridview. it looks better.but on filter ,it takes time. i need to make it fast. i read a solution in MVC , that it provides server side only.and reder all html on server.
so i raised here the question.what should i do. whether jquery datatable for 3000 or more records will work fine on clients browser if i use mvc.

You can use the Open XML SDK[^] for this.

Hi all. Probably it should have been an article, but I want to start in an informal way.
Several months ago, I found myself with a thought I cannot deploy efficiently. But every single tool had its own disadvantages:
1. Atlassian bamboo can build, but can’t deploy well. It always was a Java thing. It can’t make sites, alter web.configs and work with MSSQL.
2. Teamcity is a great product from great company, but it is a CI server wich can make packages and nothing more.
3. Octopus deploy is pretty good thing at first sight but there is a huge mess with packet versions every time I had to decide what packet versions to use and of course it cannot build.
Therefore, I decided to try making my own tool, that can build, and therefore aware of project types, can deploy and aware how things work in ASP.NET.
So please welcome! http://aspnetdeploy.com/[^]
fully open source, hosted on GitHub (wip). Begging for feedback, what do you think of it? does it seem useful for you?
