ASP.Net MVC: Calling a method from a view

This is how you call an instance method on the Controller:

@{
  ((HomeController)this.ViewContext.Controller).Method1();
}

This is how you call a static method in any class

@{
    SomeClass.Method();
}

This will work assuming the method is public and visible to the view.

Building on Amine's answer, create a helper like:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString CurrencyFormat(this HtmlHelper helper, string value)
    {
        var result = string.Format("{0:C2}", value);
        return new MvcHtmlString(result);
    }
}

in your view: use @Html.CurrencyFormat(model.value)

If you are doing simple formating like Standard Numeric Formats, then simple use string.Format() in your view like in the helper example above:

@string.Format("{0:C2}", model.value)

You can implement a static formatting method or an HTML helper, then use this syntaxe :

@using class_of_method_namespace
...
// HTML page here
@className.MethodName()

or in case of HTML Helper

@Html.MehtodName()

Controller not supposed to be called from view. That's the whole idea of MVC - clear separation of concerns.

If you need to call controller from View - you are doing something wrong. Time for refactoring.

why You don't use Ajax to

its simple and does not require page refresh and has success and error callbacks

take look at my samlpe

<a id="ResendVerificationCode" >@Resource_en.ResendVerificationCode</a>

and in JQuery

 $("#ResendVerificationCode").on("click", function() {
                getUserbyPhoneIfNotRegisterd($("#phone").val());
 });

and this is my ajax which call my controller and my controller and return object from database

function getUserbyPhoneIfNotRegisterd(userphone) {

              $.ajax({
                    type: "GET",
                    dataType: "Json",
                    url: '@Url.Action("GetUserByPhone", "User")' + '?phone=' + userphone,
                    async: false,
                    success: function(data) {
                        if (data == null || data.data == null) {
                            ErrorMessage("", "@Resource_en.YourPhoneDoesNotExistInOurDatabase");
                        } else {
                            user = data[Object.keys(data)[0]];
                                AddVereCode(user.ID);// anather Ajax call 
                                SuccessMessage("Done", "@Resource_en.VerificationCodeSentSuccessfully", "Done");
                        }
                    },
                    error: function() {
                        ErrorMessage("", '@Resource_en.ErrorOccourd');
                    }
                });
            }
