Refresh RenderBody() Content with Razor Pages - asp.net

I've got an ASP.NET project using MVC 4 and Entity Framework with the following structure:
-Controllers
-HomeController.cs
-SystemInformationController.cs
-Views
-Home
-Index.cshtml
-Shared
-MasterLayout.cshtml
-SystemInformation
-Index.cshtml
The MasterLayout.cshtml code is as follows:
<!DOCTYPE html>
<html>
<head>
<title>Sample Site</title>
<link href="~/Content/MasterPage.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="TopContent">
<a>Home</a>
</div>
<div id="LeftContent">
#Html.ActionLink("Home", "Index", "Home", new { #class = "basiclink" })
<br />
#Html.ActionLink("System Information", "Index", "SystemInformation", new { #class = "basiclink" })
<br />
</div>
<div id="MainContent">
#RenderBody()
</div>
The Index.cshtml code for the Home view is as follows:
#{
Layout = "~/Views/Shared/MasterLayout.cshtml";
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Home Page</title>
</head>
<body>
<div>
Welcome to the Sample Site.
</div>
</body>
</html>
The problem I am having is that whenever I click on either link, be it the home link or the system information link, the url simply appends a "?length=X" where X is the length of the third parameter in the ActionLink item. I want to have the content held within the Master Page to be refreshed but no matter what I do the URL seems to be built incorrectly and not refreshing the center content. Anyone have any ideas as to why that is happening?

The problem is you are using a different overload of the ActionLink method than you probably want. The one you are using is taking your third parameter and using it as the route values, not the controller name. Try changing your links to this:
#Html.ActionLink("Home", "Index", "Home", new {}, new { #class = "basiclink" })

Express Handlebars append page content to partial page

I am new to express-handlebars and finding difficulty in understanding it.
my layout
views
-layouts
-mainlayout.hbs
-partials
-header.hbs(it contains main menu)
-footer.hbs
-patialpage.hbs
pagecontent.hbs
my main page
<div>
{{body}}
</div>
this is my partial page
{{>header}}
<div>
<div>Side Bar Menu</div>
<div>Page Content Here</div>
</div>
{{>footer}}
this is my content
<div>This Content to be append in partial page</div>
You just did in the wrong sequence.
You tried to append the page content to a partial.
In the main layout you define the look of your page.
partials are e.g. parts of this layout (e.g. navbar, footer, ...)
Your main could look like:
<div>
{{> header}}
{{body}}
{{> footer}}
</div>
this means: on each side the header and the footer partial will be loaded and in between, inside {{body}} there will be the rendered view.
example of a main.handlebars file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>title</title>
</head>
<body>
{{!-- navbar partial --}}
{{> _navbar}}
{{!-- flash messages --}}
{{> _flashmessages}}
{{!-- placeholder for rendered views --}}
{{{body}}}
</body>
</html>
then you can render a view based on this main layout.
example with just a text rendered
// Index Route
app.get('/', (req, res) => {
res.send("Hello world");
});
});
example with the view index.handlebars rendered to the {{body}} part of the page
// Index Route
app.get('/', (req, res) => {
res.render('index');
});

Unable to display value which is returned from Spring controller

I'm trying to display like ${mesg}, it's not displaying the content, which is coming from the Spring controller. I have tried many ways, but no luck.
<html>
<head> <meta charset="ISO-8859-1">
<title>HOME</title>
</head>
<body>
<div align="center"> ${mesg} </div>
</body>
</html>
#RequestMapping(value="/savefile",method=RequestMethod.POST)
public String getStatus(#PathParam("pwd") String Pwd,ModelMap map){
System.out.println(":::pwd::"+Pwd);
map.addAttribute("mesg", "Welcome to mBOK");
return "Success";
}

cant apply stylesheet to "input-validation-error " class [duplicate]

I have found a few questions relating to this, but generally there are many different answers and they all seem very messy and complex.
If that is what needs to be done, then ok i better sit down and tackle it.
I want to know what the simplest and most efficient way is to add content to your head from partial views.
Reason I need to do this is i need certain java script and jquery on each page and it differs from page to page. I donot just want to add them all in the _layout view.
You can do this with sections. For example:
I have more than two view which each other has same _Layout.My Index action in Company Controller has a sections as follow:
#model Invoice.Model.HelperClasses.CompanyViewModel
#{
ViewBag.Title = "Companies";
Layout = "~/Views/Shared/_Layout.cshtml";
}
#section usage{
<link href="~/css/uniform.default.css" rel="stylesheet" />
}
#section other{
<link href="~/css/datepicker.css" rel="stylesheet" />
<link href="~/css/SimpleSlide.css" rel="stylesheet" />
<link href="~/css/responsive-tables.css" rel="stylesheet" />
}
#section script
{
<script src="~/js/datepicker/bootstrap-datepicker.js"></script>
}
and Display Action in Invoice controller has same sections but different css and js as follow:
#model Invoice.Model.HelperClasses.InvoiceViewModel
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
#section usage{
#*<link href="~/css/uniform.default.css" rel="stylesheet" />*#
}
#section other{
<link href="~/css/DT_bootstrap.css" rel="stylesheet" />
<link href="~/css/responsive-tables.css" rel="stylesheet" />
<script src="~/js/datatables/extras/ZeroClipboard.js"></script>
}
#section script
{
<script src="~/js/datepicker/bootstrap-datepicker.js"></script>
<script src="~/js/validate/jquery.metadata.js"></script>
<script src="~/js/validate/jquery.validate.js"></script>
}
and then you can use this section in _Layout but its required argument should be false. Look at:
<!DOCTYPE html>
<html>
<head>
<!--usage-->
#RenderSection("usage", required: false)
<!--other-->
#RenderSection("other", required: false)
<!--script-->
#RenderSection("script", required: false)
<head>
<body>
</body>
</html>
On your _Layout.cshtml page (Or any other master page) Use following code on inside of <head></head> tag.
#if (IsSectionDefined("SpecialOther"))
{
#RenderSection("SpecialOther")
}
On the page that you want special css,script or any other item, specify their refernces. e.g.,
#section SpecialOther{
<link href="~/css/responsive-tables.css" rel="stylesheet" />
<script src="~/js/datatables/extras/ZeroClipboard.js"></script>
}

angularjs route with spring framework

I've developed a simple web page with angularjs and spring framework.
I tried to make the web page using angular route so that web page work as SPA.
Here's my simple main jsp file. The page is shown when I access to 'http://localhost:8080/test' on the chrome.
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%# page session="false" contentType="text/html; charset=UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>Home</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular-route.min.js"></script>
<script>
angular.module("app", ['ngRoute'])
.config(function($routeProvider) {
$routeProvider.when("/home", {
templateUrl: "home.html",
controller: "controller"
})
})
.controller("controller", function() {
});
</script>
</head>
<body ng-app="app" ng-controller="controller as main">
<ul>
<li>HOME</li>
</ul>
<ng-view></ng-view>
<div ng-view></div>
</body>
</html>
I want to put the home.html into <ng-view> or <div class="ng-view"> when I click the 'HOME' link without page refresh but it's not working.
What's the problem with the code?
To get it to work change href="#/home" to href="#!home"
Also, make sure home.html is in the /src/main/resources/static/ directory
I would prefer to use .html with Thymeleaf instead of .jsp

#RenderSection in nested razor templates

My problem is I can't seem to use #RenderSection from a nested template when #RenderSection is defined in the base template. Currently, I have a nested base template which is linked to a child template which is then used in the view pages. When I define the #RenderSection in the base template and render it in the view pages it throws an error.
Here's the exact problem.
I want to create a RenderSection to allow me to insert custom scripts.
My base template....
<!DOCTYPE html>
<html>
<head>
<title>#ViewBag.Title</title>
#RenderSection("HeaderContent", false) // The region of the header scripts (custom css)
</head>
<body>
#RenderBody()
</body>
</html>
I then skip the child template as I do not want to put any custom head code in there and apply it to the page itself..
#section HeaderContent {
<script>alert("hi");</script>
}
My problem is that I cant seem to add custom head code in to the base template from my normal pages.
The following sections have been defined but have not been rendered for the layout page ~/Views/Shared/OneColLayer.cshtml": "HeaderContent.
Do I need to include a pointer to the base template in the view page?
#{
Layout = "~/Views/Shared/BaseTemplate.cshtml";
}
My new base template
<head>
<link rel="stylesheet" type="text/css" href="#Url.Content("~/content/layout.css")" />
<link rel="stylesheet" type="text/css" href="#Url.Content("~/content/global.css")" />
<script type="text/javascript" src="#Url.Content("~/Scripts/jquery-1.5.1.min.js")"></script>
<script type="text/javascript" src="#Url.Content("~/js/fadeInFadeOut.js")"></script>
<title>#ViewBag.Title</title>
#RenderSection("HeaderContent", false)
</head>
<body>
#RenderBody()
</body>
my new child template
#{
Layout = "~/Views/Shared/BaseTemplate.cshtml";
}
#RenderSection("HeaderContent", false)
#RenderBody()
my view
#{
ViewBag.Title = "Home";
Layout = "~/Views/Shared/OneColLayer.cshtml";
}
#section HeaderContent {
<h1>Left Content</h1>
}
<div>my view content</div>
the content gets placed in the oneCol template now the base template.
results...
<div id="Content">
<h1>Left Content</h1>
</div>
You need to specify the sections that are allowed to pass through in the middle template.
BaseTemplate.cshtml
<!DOCTYPE html>
<html>
<head>
<title>#ViewBag.Title</title>
#RenderSection("HeaderContent", false) #* The region of the header scripts (custom css) *#
</head>
<body>
#RenderBody()
</body>
</html>
EDIT
your new child template
#{
Layout = "~/Views/Shared/BaseTemplate.cshtml";
}
#section HeaderContent {
#RenderSection("HeaderContent", false)
}
#RenderBody()
If you put the render section inside of a section from the base template, it will render that section in the correct place on the base template.
View.cshtml -> uses MiddleLayout.cshtml as it's layout
#section HeaderContent
{
<!-- header content that will now render -->
}
<!-- page content -->
