I've implemented a custom html helper extension method to render a partial view into my razor page and I'm concerned that the method I've used is "too heavy"...
I want to use a common spinner across my web project. The spinner I'm using requires a number of elements:
<div class="panel-spinner-container">
<div class="sk-spinner sk-spinner-cube-grid">
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
<div class="sk-cube"></div>
</div>
<div class="panel-spinner-msg"><p>loading...</p></div>
</div>
Rather than including this in razor code every time I want a spinner, I figured I'd toss it into an html helper method, so I could do this:
<div>
#Html.PanelSpinner()
</div>
I created a partial view for this which just contains the divs from above, and an html helper extension method:
public static MvcHtmlString PanelSpinner(this HtmlHelper html) {
var controllerContext = html.ViewContext.Controller.ControllerContext;
var viewData = html.ViewData;
var tempData = html.ViewContext.TempData;
using (var stringWriter = new System.IO.StringWriter()) {
var viewResult = ViewEngines.Engines.FindPartialView(controllerContext, "PanelSpinner");
var viewContext = new ViewContext(controllerContext, viewResult.View, viewData, tempData, stringWriter);
viewResult.View.Render(viewContext, stringWriter);
var stringResult = stringWriter.GetStringBuilder().ToString();
return new MvcHtmlString(stringResult);
}
}
This seems like an awful lot of processing required to render a spinner. What is the performance overhead on this type of method? Is it normal to use a helper for this type of scenario, or am I overkilling this? Is there a better (more performant) way to do this?
I very much like the ease of use but am concerned about performance (e.g., I could just use #Html.RenderPartial(...), but then I have to remember the name of the spinner partial, etc. The helper method wrapper is so much easier to use)
To render a partial view using an extension method, you can make use of the built in Partial() method of HtmlHelper. It can simply be
public static MvcHtmlString PanelSpinner(this HtmlHelper html)
{
return html.Partial("PanelSpinner");
}
Note: You need to include using System.Web.Mvc.Html;
In ASP.NET web forms it is possible to modify page controls from the master page. For example, on a page "/Sample" I could set TextBox1 as readonly by doing the following.
//Site.master.cs
protected void Page_Load(object sender, EventArgs e)
{
if (Request.Path.ToUpper().Contains("/SAMPLE"))
{
TextBox TB = MainContent.FindControl("TextBox1") as TextBox;
TB.ReadOnly = true;
}
}
The question is... Is there an equivalent way to do this in an MVC application that uses a SiteLayout?
Background: We have purchased an MVC application and have access to modify the
source code. We need to customize the behaviors on some of the pages. It
will only be used by a few dozen people so a performance hit won't really be noticeable. If this was a Web Forms
application we would use the above method. However this application
is written with MVC and it is making our web form programmer (me) confused on how best to proceed. Customizing numerous pages is going to be a headache when
we have to patch the software. Having all the changes in one central location
would be easier to manage going forward. How can you have one place where you can customize other pages programmatically in MVC?
There is no MVC equivalent for FindControl, since views are built in a single operation, where ASP.NET controls are built up and modified over several different events. You don't need to find the control, you specify all of its attributes as it is built.
The rough equivalent to an ASP.NET control (at least in this context) is an HTML helper. HTML helpers are implemented as static extension methods, which allows them to be shared between views and perform some actions as the view is loaded.
using System.Web.Mvc;
using System.Web.Mvc.Html;
public static class MyExtensions
{
public static MvcHtmlString TextBox1(this HtmlHelper helper, string name)
{
if (helper.ViewContext.HttpContext.Request.Path.ToUpper().Contains("/SAMPLE"))
{
return InputExtensions.TextBox(helper, name, null, new { #readonly = "readonly" });
}
return InputExtensions.TextBox(helper, name);
}
}

Note that it is also possible to put the logic directly in the view, but then you cannot reuse logic in other views and it makes your view look cluttered.
As for reading the data back out of a textbox, you need to put it within a <form> tag so it can be posted to a controller action method, which is the rough equivalent of a submit button click event. Unlike ASP.NET, MVC supports multiple <form> tags so you don't have to mix your logic for different actions on the page.
Your question is very broad. But generally, if you want to provide read only rendering for your controls in your razor views based on some conditions, you can try the below approach.
You should add a IsReadOnly property to your view model and use that to render the control the way you wanted.
public class CreateCustomerVM
{
public bool IsReadOnly {set;get;}
//Other properties goes here
public string Email { set; get; }
public string Name { set; get; }
}
In your Action method set the IsReadOnly propery value based on your condition.
public ActionResult Index()
{
var vm=new CreateCustomerVM();
//Set the value based on your condition
vm.IsReadOnly=true;
return View(vm);
}
And in your view , you use the IsReadOnly property to determine whether you want to display a readonly control or not.
#model YourNameSpaceGoesHere.CreateCustomerVM
#using (Html.BeginForm())
{
#Html.TextBoxFor(m => m.Email)
if(Model.IsReadOnly)
{
#Html.TextBoxFor(m => m.Name, new { #readonly = "readonly" })
}
else
{
#Html.TextBoxFor(m => m.Name)
}
<input type="submit"/>
}
In Asp.net MVC3 when you write below code , it generates wrapping html itself
#using (Html.BeginForm()) {
#Html.ValidationMessageFor(model => model.Text)
}
It generates codes in below format,
<form method="post" action="/Feeds">
<!-- Fields Here -->
</form>
My question in #using (Html.BeginForm()) automatically adds <form> tag at beginning and end, how can i create something like that of my own.
I am looking for some thing like below
#using (Html.BeginMYCUSTOMDIV())
{
I am text inside div
}
Expected Generated Output
<div class="customDivClass">
I am text inside div
</div>
Something along the lines:
public class MyDiv : IDisposable
{
private readonly TextWriter _writer;
public MyDiv(TextWriter writer)
{
_writer = writer;
}
public void Dispose()
{
_writer.WriteLine("</div>");
}
}
public static class MyExtensions
{
public static MyDiv BeginMYCUSTOMDIV(this HtmlHelper htmlHelper)
{
var div = new TagBuilder("div");
div.AddCssClass("customDivClass");
htmlHelper.ViewContext.Writer.WriteLine(div.ToString(TagRenderMode.StartTag));
return new MyDiv(htmlHelper.ViewContext.Writer);
}
}
and in the view:
#using (Html.BeginMYCUSTOMDIV())
{
<span>Hello</span>
}
generates:
<div class="customDivClass">
<span>Hello</span>
</div>
If I'm not mistaken, Html.BeginForm() returns an IDisposable object. When used in the using block, the object's Disposemethod is called, which is the responsible to write the closing tag to the output.
how does using HtmlHelper.BeginForm() work?

Your problem is that the CatalystModel class doesn't have a default constructor so the default model binder cannot instantiate it here:
[ChildActionOnly]
public ViewResult SearchView(CatalystModel model)
{
return View(model);
}
This being said having such a child controller action that you are invoking like this:
<% Html.RenderAction("SearchView", ViewData["catalystItems"]); %>
is totally useless and bring strictly no value.
Why don't you render the partial directly:
<% Html.RenderPartial("SearchView", ViewData["catalystItems"]); %>
You should also read the Haacked blog post to better understand the differences between RenderAction and RenderPartial.
Or if you really (for some cryptic reason) have controller actions that take some models which do not have default constructors as action parameters you will need to write a custom model binder for this type and specify which of your custom constructors should be used to instantiate it and what values should be passed to it of course.
Try this:
<% Html.RenderAction("SearchView", new { model = ViewData["catalystItems"] }); %>
