Custom html helpers can be created by extension methods. Extension method can be crated by static methods in static class. In my example I am going to create two custom html helpers for html submit button and for image.In built-in or standard html helpers there are no helpers for submit and for image.
Step: First we add class in project folder and write following code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace CustomHTMLHelpers
{
public static class CustomHtmlHelpers
{
public static MvcHtmlString Submitbtn(this HtmlHelper mvc, string name, string value)
{
string str = ("<input type='submit' value=" + value + " name=" + name+" />;");
return new MvcHtmlString(str);
}
public static MvcHtmlString Img(this HtmlHelper mvc, string src, string alt)
{
var ctrl = new TagBuilder("img");
ctrl.MergeAttribute("src", src);
ctrl.MergeAttribute("alt", alt);
ctrl.MergeAttribute("width", "200px");
ctrl.MergeAttribute("height", "200px");
return MvcHtmlString.Create(ctrl.ToString(TagRenderMode.SelfClosing));
}
}
}
Step 2: Create New Controller and create and action into that controller.
public ActionResult Index()
{
return View();
}
step3: Add View and write following code.
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
@Html.Submitbtn("aa","bb")
@Html.Img("../images/Desert.jpg","This is Image");
</div>
</body>
</html>Output:
Thank you for the effort, keep up the great work
