Render plain html in Master Page web form - html

I'm writing a web application in ASP.NET Web Forms. I have a Master Page and I will include some knockout templates inside. For some structural reasons I don't want to add that templates inside the Master Page code directly, so they will be in differents files.
Structure.
Masterpage.master
template1.template.html
template2.template.html
template3.template.html
I have done the same thing in MVC, but it was easy just rendering partials.
Is there anyway to do the same thing with a helper class or something?
I need that code in every page that includes that Master Page.

Create a user control (.ascx) file and move the required markup out of your HTML files and into the ASCX files. Then register the controls (at the page or web.config level) and use them in your master page.
See Also: When do you need .ascx files and how would you use them?

Modularization of html content in Electron app

I know a typical practice to build an Electron app is to follow SPA (Single Page App). I still would like to split my html content into separate files for easy maintenance. There is still the main index.html file which is to be loaded on startup.
My question is: is there a protocol for inserting a part of html content from a different files? For eg. in Django, there is a include and extend tags where you can insert an entire html file into the body of another parent html file or retain certain features from another html file.
There's no way to do this directly. Django is a server-side framework, so you can assemble your HTML on the server, and the completed HTML is sent to the client/browser. With Electron, you're basically running Chromium with Node.js APIs added, loading your HTML from the filesystem, so there's no server to do any HTML assembly in.
However, if you just want to break up your HTML into pieces for easier maintenance, but you're not doing any of your include/extend dynamically, theoretically, you could use some kind of templating system or a static site generator to combine your HTML files statically at build time.
Here's an list of some JS templating engines: https://expressjs.com/en/resources/template-engines.html
Here's a list of some static site generators (filter language by JavaScript): https://jamstack.org/generators/

Isn't the html of the form Django displays on the screen?

Django shows you forms when you do basic coding, right?
Where is the html of the automatically generated form in windows?
So instead of looking for a template folder, once the developer writes the url or views code, he finds the location of the skeleton-only html that Django shows.
In my opinion, it looks like it's built somewhere like an "anaconda/envs" contains a separate virtual environment, but I can't find it.
it's maybe path?
It's well documented:
https://docs.djangoproject.com/en/2.2/ref/forms/renderers/
It loads templates first from the built-in form templates directory in
django/forms/templates
unless you have 3rd party libraries included that override these templates.
However, a quick check in https://github.com/django/django/tree/master/django/forms/templates/django/forms/ shows that this directory is empty.
tl;dr
Django does not render any forms from scratch (unless it's the Admin which of course creates its whole UI automatically). It just enables you to quickly create a template that can render your form but you will still have to provide a basic template (aka HTML markup with dynamic parts) yourself.

How to emulate the behavior of master page in Net.Core and VS Code

When building an MVC project, there's a shared folder automatically provided in which I have Layout.cshtml page that's used like the holder or master page (as it was called in Web Forms). So, all the banners, navbars, footers etc. go in there, while the acutal pages being developed refer to it in the source code and got pasted together upon rendition. This far I'm following.
Now, I have a set up and AspNet website using Yeoman and the only thing I have is wwwroot directory in which I put the file start.html. (It's the same as index.html - I just wanted to try out if I have full control over default files.)
I'm unsure how to proceed. I.e. I'd like the links on the start.html to point to files like uno.html, duo.html etc. and read those into a designated part of the landing page (i.e. start.html).
Is it doable without using the magic of templates? I want to have full control over the rendition process.
There's no point googling it, I noticed, because anything I've got the last two hours leads to how to create master page not to how to emulate master page.
Well, the static files middleware is just for that: static files.
You roughly have two options:
Do everything client sided, i.e. rather than having normal links use javascript/ajax calls and embed the content of the static file in your start.html using javascript.
It should work, but has several down-sites like it requires javascript to work (not a big issue these days, except for the paranoids who use no-script browser extensions) and that web crawler still may have issues properly indexing ajax heavy web pages
Wait until ASP.NET Core 1.2 (scheduled for Q1-Q2 2017), which will add Razor Pages. Pages rendered with Razor template engine, but without the need of a controller.
1.2
WebSockets
SignalR
Razor Pages (Views without MVC controllers)
Web API security
If you don't wanna wait, try RazorLight, which is 3rd party open source library for rendering Razor views.
But all except the first one require some "magic template engine".
You could of course write an server-sided includes (SSI) middleware which would be based on UseStaticFiles middleware and parse the file and include the html files server sided before returning it. There is nothing out of the box for it as far as I know.

How do you work with include pages in jsp or php or the likes without getting IDE / Editor warnings for CSS classes?

If the CSS files for your site are referenced in the parent page, obviously you can use those CSS rules and classes in the sub-page or "included" page (like a jsp include or a php include). That will run as expected in the browser. BUT, if you are using an IDE or smart text editor of some kind (I'm using Netbeans), you will get warnings about the CSS elements in the sub-page (a .jspf for example) unless that file has a redundant reference to the css files. Is there a work-around for this? I don't want to have to reference the CSS files in both my jsp and my jspf (jsp include).
One technique I've used is to abandon jspf files in favour of a templating system where if you want to include something from a template, the template is actually a full page of which part is marked to be included. I actually use a home-grown template system for this, but my understanding is that thymeleaf (http://www.thymeleaf.org/) offers the same feature.

How to apply same content to multiple html pages

I'm new to html and was wondering if there is a way to apply the same content to many html files at once.
For example, if I have many pages, but all those pages have an identical navigation side panel that contains links to all the other pages. Is there any way to change the contents of this side panel without changing it for each individual page?
i.e. is there a feature that allows me to make this navigation panel in a separate file, then tell all my pages to include this navigation file?
I know a css file can control the format of many html pages - is there an analogy to this that can control the content of many html pages?
You can use PHP to do that. Write the HTML code in PHP file, then add include statement in your HTML. This saves you from having to write same code again and again specially for navigation, etc.
PHP manual explains it.
Hope it helps.
You can write the common content in javascript file and include it in your html pages using script tag:
<script src="YOUR_FILE.js"></script>
You can use an online HTML to Javascript converter like this one to generate you javascript code.
Server-side includes or server-side programming languages (like PHP, for example), are often used to do that. All pages just include a shared common file, which contains the common content.
<?php
include(file with extension);
?>
You'd have to change your file extension that runs this code to DOT php
