Clicking 2 submit buttons in the same page

I have a project in .Net Core with Razor Pages and I have the form bellow that contains some input fields and 2 submit buttons.
<form class="form-style" method="post" id="createForm">
<div class="form-group button-position col-md4">
<input type="submit" id="placeRequest" name="placeRequest" value="Place Request" class="btn btn-primary" />
</div>
<div class="form-group button-position col-md4">
<input type="submit" value="GetHour" asp-page-handler="Hour" class="btn btn-primary btn-style" formnovalidate />
</div>
</form>
I need to be able to click the first submit button (GetHour) and then click the second one (Placer Request)
In my Razor Page model I have
public async Task<IActionResult> OnPost()
{
//code that will be executed when the Place Request button is clicked
}
public async Task OnPostGetHour()
{
////code that will be executed when the Get Hour button is clicked
}
The problem is that I am not allowed to make the 2 submits. If I only do one of them, it works but the second one does nothing
Is there any way I could make both of the submits?

This is because once you click the first submit button, The page does a redirect and loads again.
This is the nature of form submission. If you want to click both the buttons. Change the button type from "submit" to "button".
Then create 2 click handlers and handle the form submitting using Ajax
<form class="form-style" method="post" id="createForm">
<div class="form-group button-position col-md4">
<input onclick="onBtn1Click()" type="button" id="placeRequest" name="placeRequest" value="Place Request" class="btn btn-primary" />
</div>
<div class="form-group button-position col-md4">
<input onclick="onBtn2Click()" type="button" value="GetHour" asp-page-handler="Hour" class="btn btn-primary btn-style" formnovalidate />
</div>
</form>
Then write 2 JavaScript functions
function onBtn1Click()
{
//Submit code via Ajax here
}
function onBtn2Click()
{
//Submit code via Ajax here
}

Radio Button Toggle call C# Function

i build this application:
CRUD Application with ASP.NET Core 3.0 & Entity Framework 3.0 Using Visual Studio 2019
Now i found a nice toggle(https://codepen.io/shaneheyns/pen/OPWGry):
i will only have the toggle like this code:
<div class="pricing-switcher">
<p class="fieldset">
<input type="radio" name="duration-1" value="monthly" id="monthly-1" checked>
<label for="monthly-1">Monthly</label>
<input type="radio" name="duration-1" value="yearly" id="yearly-1">
<label for="yearly-1">Yearly</label>
<span class="switch"></span>
</p>
</div>
everything works(i copied the .css style), but how can i execute a C# function if monthly is checked?
i searched a lot and tried alot but nothing worked.
the only things is a extra submit button.
but i will something like an Onchange event or something that called a C# Function in my Controller.
if i have a button i would code it like this:
<a asp-action="monthly">Test!!</a>
Can somebody please help me?
Thank you!
now i updated my Code like this:
#using (Html.BeginForm("test1", "Test"))
{
<div class="pricing-switcher">
<p class="fieldset">
<input type="radio" name="Isactive" value="test1" id="monthly-1"checked>
<label for="monthly-1">monthly</label>
<input type="radio" name="test1" value="test2" id="yearly-1">
<label for="yearly-1">yearly</label>
<span class="switch"></span>
</p>
</div>
and the .js Code:
$(document).ready(function () {
$("input[name='Isactive']").change(function () {
$(this).closest("form").submit();
});
});
now the function in Controller is like this:
public void Isactive()
{
Debug.WriteLine("test");
}
The Function was called thanks! But 2 problems:
The switch does not toggle
On click the site will redirect to IsActive the browserlink is https://localhost:44311/Test/Isactive
How to fix these?
Sorry i know C#, but html/js/css are new to me

The switch does not toggle
For the first question, You should keep the name of two radio button the same.
<div class="pricing-switcher">
<p class="fieldset">
<input type="radio" name="duration-1" value="test1" id="monthly-1"checked>
<label for="monthly-1">monthly</label>
<input type="radio" name="duration-1" value="test2" id="yearly-1">
<label for="yearly-1">yearly</label>
<span class="switch"></span>
</p>
</div>
On click the site will redirect to IsActive the browserlink is https://localhost:44311/Test/Isactive
For the second question, This is the default behavior for form submission, the form points to this url. If you want to stay at the current page, you can submit the form with ajax.

Focus back on textbox after submitting using ASP.NET Core MVC

I am trying to introduce a dynamic search function in my project. I have created a search form in my view which submits on keyup but the issue that I'm not facing is that when the view reloads, the text box is no longer in focus and so the user needs to click back onto it which obviously isn't ideal.
My view is set up as follows:
<form id="searchForm" asp-action="Index" method="get">
<div class="row">
<div class="col-9">
<input type="text" id="fooSearch" name="searchString" value="#ViewData["currentFilter"]" class="form-control" />
</div>
<div class="col-3">
<div class="row">
<div class="col-6">
<input type="submit" value="Search" class="btn btn-outline-secondary form-control" />
</div>
<div class="col-6">
<a asp-action="Index" asp-route-recent="true" class="btn btn-outline-secondary form-control">Recent</a>
</div>
</div>
</div>
</div>
</form>
with the following JQuery script to submit on keyup
$(function () {
$('#fooSearch').keyup(function () {
$('#searchForm').submit();
});
});
</script>
Can anyone help me to retain focus on the search textbox when the DOM is loaded?

To give the focus back to the searchbar, you can use jQuery's focus(), e.g.:
$("#fooSearch").focus();
Now, where you place this depends on whether your form submit is synchronous (and makes the page reload) or asynchronous.
If the submit is asynchronous, then you can place this in your keyup event handler, right after the code that submits:
$('#fooSearch').keyup(function () {
$('#searchForm').submit();
$("#fooSearch").focus(); //focus back on the search bar
});
Otherwise, you will need to call focus() from an onload event:
$(document).ready(function() {
$("#fooSearch").focus();
});

In all cases, first load or reload (submit), the focus should be on the search textbox so I think that you can just focus the textbox on load.
$(function() { $("#fooSearch").focus();});
The problem you may encouter is that the cursor will not be in the end of the keywords. So I think that the best option here is to use Ajax to the update the results each time the user change the keywords. Maybe waiting a few seconds before each update is a good idea also.

If you are using html5 you can just add autofocus to your html tag something like:
<input type="text" id="fooSearch" autofocus ="autofocus" name="searchString" value="#ViewData["currentFilter"]" class="form-control" />

html button is activating asp validation in html input form - Why?

I'd want to ask why after clicking on my custom button that just appends text to div that's inside form, then it activates asp validation of that form?
<form asp-action="Create">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="Name" class="control-label"></label>
<input asp-for="Name" class="form-control" />
<span asp-validation-for="Name" class="text-danger"></span>
</div>
<div id="append_area">
</div>
<button id="appendChild" onclick="addText()">add new thing</button>
<div class="form-group">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</form>
<script>
function addText()
{
var div = document.getElementById('append_area');
div.innerHTML += `test`;
}
</script>

Set your button type as button
<button type="button" id="appendChild" onclick="addText()">add new thing</button>

As described in W3C documentation, default type of the <button> element can vary across different browsers, so it is a good practice to always specify it explicitly.
In this case, the default value is submit, so by clicking the button you are inadvertently causing the submit action and hence also validation to be performed as well.
To fix this, just specify the button type explicitly as button:
<button type="button" />

You can also do this:
<script>
function addText()
{
var div = document.getElementById('append_area');
div.innerHTML += `test`;
return false;
}
</script>
then you can call in code onclick="return addText()"

When you submit a form to a CGI program that resides on the server, it is usually programmed to do its own check for errors. If it finds any it sends the page back to the reader who then has to re-enter some data, before submitting again. A JavaScript check is useful because it stops the form from being submitted if there is a problem, saving lots of time for your readers.
<button type="button" id="ChildForm" onclick="add()">add new </button>
The CGI script is still more reliable, as it always works regardless of whether JavaScript is enabled on the client-side or not; but having this extra safety barrier is a nice thing to have in place. It makes your page much more user-friendly and takes out the frustration of having to fill out the same form repeatedly. It's also very precise, as you can point out the exact field where there's a problem.

Check if button has been submitted

i have a page with multiple forms like this: (all of them have different names
<form method="post" name="form1">
<input type="text>
<input type="text>
<input type="text>
<input type="text>
<button type="submit" name="button1" class="btn btn-icon btn-primary glyphicons circle_ok"><i></i>Save changes</button>
</form>
This is the code i'm using to check which form is submitted:
if(IsPost && !Request["button1"].IsEmpty()) {
}
the code above only works if i submit the form through an <input type="submit" name="button">
i wanted to know if there's any way to know which form is submitted with a button type=submit (the one that's in the form i posted above)

This is because the value of the a <button> element is not posted. You could add a hidden field to your form:
<input type="hidden" name="formname" value="myform" />
Then check for this in your code:
if(IsPost && Request["formname"] == "myform") {
}
