    linkText As String, _
    actionName As String, _
    routeValues As Object, _
    ajaxOptions As AjaxOptions, _
    htmlAttributes As Object _
) As MvcHtmlString
public static MvcHtmlString ActionLink(

[ExtensionAttribute]
public:
static MvcHtmlString^ ActionLink(
    AjaxHelper^ ajaxHelper, 
    String^ linkText, 
    String^ actionName, 
    Object^ routeValues, 
    AjaxOptions^ ajaxOptions, 
    Object^ htmlAttributes
)

Parameters

  • linkText
    Type: System.String
    The inner text of the anchor element.
  • routeValues
    Type: System.Object
    An object that contains the parameters for a route. The parameters are retrieved through reflection by examining the properties of the object. This object is typically created by using object initializer syntax.
  • htmlAttributes
    Type: System.Object
    An object that contains the HTML attributes to set for the element.

Return Value

Type: System.Web.Mvc.MvcHtmlString
An anchor element.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type AjaxHelper. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Exceptions

Exception Condition
ArgumentException

The linkText parameter is null reference (Nothing in Visual Basic) or empty.

Remarks

This method renders an anchor element. When the user clicks the link, MVC asynchronously invokes the specified action method via an HTTP POST request. The response of that action method can be used to update a specified DOM element, depending on which AjaxOptions are specified.

The htmlAttributes parameter consists of an object that contains name/value pairs. The attributes that are specified in the name/value pairs depend on the HTML element that is being rendered. For example, for an anchor (a) element, you might provide the following anonymous object:

new { target="_self", name="summary" }
New With {.target="_self", .name="summary" }
