Create a custom ActionLink

问题:

I want to create a custom actionlink but I don't know how to do this while fulfilling my needs. I worked with custom htmlhelpers before but this is a bit more tricky for me.

The actionlink that I want to call needs to be like this:

@Html.CustomActionLink("LinkText", "Area","Controller","TabMenu","Action",routeValues, htmlAttributes)

so an example would be:

 @Html.CustomActionLink("Click here","Travel","Trip","Index","Index", new { par1 = "test", par2 = test2, new { @class = "font-color-blue" })`

Which would generate this html:

<a class="font-color-blue" href="/Trip/Travel/Index/Index?par1=test&par2=test2">Click Here</a>

And my route looks like:

 context.MapRoute(
            "EPloeg_default",
            "EPloeg/{controller}/{tabmenu}/{action}/{id}/{actionMethod}",
            new { action = "Index", id = UrlParameter.Optional, actionMethod = UrlParameter.Optional }
        );   

Any ideas how I can make this?

回答1:

How about following code,

@Html.ActionLink("Click here","Trip","Index", new { area= "Travel", tabmenu= "Index"}, new { @class = "font-color-blue" })

EDIT

You can use a extension method like this,

public static MvcHtmlString CustomActionLink(this HtmlHelper htmlHelper, string linkText, string area, string controller, string tabMenu, string action, RouteValueDictionary routeValues, IDictionary<string, object> htmlAttributes)
{
    routeValues.Add("area", area);
    routeValues.Add("tabMenu", tabMenu);
    return htmlHelper.ActionLink(linkText, actionName, controllerName, routeValues, htmlAttributes);
}

回答2:

You can implement custom Action Link extensions, you have to write your own method inside LinkExtensions class:

namespace TestCustomHelper.Html
{

public static class LinkExtensions
{
public static MvcHtmlString ActionLinkAuthorized(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName, RouteValueDictionary routeValues, IDictionary<string, object> htmlAttributes, bool showActionLinkAsDisabled)
  {
     if (htmlHelper.ActionAuthorized(actionName, controllerName))
     {
       return htmlHelper.ActionLink(linkText, actionName, controllerName, routeValues, htmlAttributes);
     }
     return MvcHtmlString.Empty;
}

}

and use it in view:

@using TestCustomHelper.Html


@Html.ActionLinkAuthorized("Create New", "Create", new { org = ViewBag.OrgBranchID }, new { @id = "linkCreateEmployee" },true) 

NOTE:

I have added one extara bool parameter if you see the last parameter of the method, you can add more according to your need.

i just wrote one overload for it according to my needs, you can write all overloads as Html.ActionLink() has.

See my tutorial on Creating Custom Html Helper Extensions in asp.net mvc
