I have this function to return a view

Function mostrar(cor As String, alinea As Char) As ActionResult
           ViewBag.cor = cor
           ViewBag.alinea = alinea
           Return View()
       End Function

this is the view

Razor

@Code
    ViewBag.Title = "mostrar"
    End Code

<h2>mostrar</h2>
<h4>@viewbag.cor</h4>
<h4>@ViewBag.alinea</h4>

the function is called from code but no view is returned. But i know the parameters enter function.

if i put this in the URL:
http://localhost:16844/prescavi/mostrar?cor=red&alinea=s

The view works perfectly...

"the function is called from code" how exactly (from view or from controller)?

I don't know the best way to this.
I have an input form and I pass the values to the controller by json.
Then the controller executs several methods and gets to a few results in strings or collections.
Those results must pass to a view.
(if the inputs are right the view returns a green light and an ocasional OK and if there are errors either a yellow or a red light and a description of why there's an error)

Calling the code as a function isn't going to generate html. If that's what you want to do then google "asp.net get html from controller programmatically" and you'll find examples of how to get the rendered html.

Use "Reply", so I get notified about your message. I got here by accident, and I saw your comment.

To be short: you can't make an ajax call and expect a "regular" effect. You either use ajax to talk to the backend or do regular POSTs or GETs.

When designing ajax backend call you can decide what that will return. It can return html (a partial view in your case) you can directry render into the current DOM, or json (xml, plain text, whatever) that you can parse and format as necessary on client side.

The simplest approach is using AjaxForm[^].

This is about the partial view approach: https://cmatskas.com/update-an-mvc-partial-view-with-ajax/[^]

On the other hand you have jQuery and you can tailor your ajax behavior as you like.
