Razor: OnGet And OnPost

Question

User-1590999572 posted

Visual Studio Code 1.48 | .NET Core 3.1

Hi all

Two Methods can be used to process Forms: Get and Post

In the Razor Pages, in the Archive; for example Index.cshtml.cs the structure is implemented:

public class IndexModel : PageModel
{
    public void OnGet()
    {

    }
}

As can be seen, it works exclusively with Razor Pages without MVC Controllers

1 ° How to implement a Form in the Index.cshtml File to be processed by this same page, obviously using the OnGet Method?

2 ° Is it the same procedure for the OnPost Method (method = "post") or is there an additional variant?

Thank you very much

Forms are typically POSTed.  It's possible to submit parameters in the URL (GET) but atypical.  

2 ° Is it the same procedure for the OnPost Method (method = "post") or is there an additional variant?

Your question is not clear.  I recommend going through a beginning level tutorial to understand basic Razor Page programming pattern.

Mgebhard, Thanks for your reply, but ...

The Microsoft samples are very specific to a workbench, in addition to using their repositories on GitHub.

What I require is something simpler and more practical:

1º How to develop a simple Form to process Data that initially will not be entered into the Database but will be previously analyzed on the same page, for example Index, or on another, that is, retrieve and view the Data previously and if necessary apply certain processes to them before being entered into the Database?

2º How to establish and use the connection string to link with SQL Server 2014?

3rd Is the Scaffolding Tool mandatory? How to implement this utility to customize it according to specific requirements?

Please remember that the work is exclusively with Razor Pages and not with the MVC Architecture (that is, there are no Controllers)

Thank you very much already

Clearly, you did not bother going through the tutorial.  Again, your asking very basic question covered in any beginning level Razor Pages tutorial.  It makes no sense to copy the tutorial here.

The following link covers saving data in a database using Razor Pages.
