Question

I have my main view like this:

<%@ Page Title=”” Language=”C#” MasterPageFile=”~/Views/Shared/Site.Master” Inherits=”System.Web.Mvc.ViewPage” %>

Index

<script src="../../Scripts/jquery-1.3.2.js" type="text/javascript"></script>

<script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script>

<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>

<h2>
    Index</h2>

<script type="text/javascript">
    $(function() {
        $('#mylink').click(function() {
            $('#resultpartial1').load(this.href);
            return false;
        });
    });

    $(function() {
        $('#mysecondlink').click(function() {
            $('#resultpartial1').load(this.href, { id: 123 });
            return false;
        });
    });
</script>

<%= Html.ActionLink("click me","Partial1","Foo",new MyViewModel { Foo = "123" , Bar="456" },new { id = "mylink" }) %>
<%= Html.ActionLink("click me second link","Partial2", "Foo", new { id = "123" }, new { id = "mysecondlink" }

) %>

and controller like this:

public class FooController : Controller
{
    //
    // GET: /Foo/

    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Partial1(string id)
    {
        // TODO: use the id to fetch the model from somewhere
        MyViewModel model = new MyViewModel { Bar = "a", Foo = "1" };
        return View(model);
    }

    public ActionResult Partial2(string id)
    {
        // TODO: use the id to fetch the model from somewhere
        MyViewModel model = new MyViewModel { Bar = "b", Foo = "2" };
        return View(model);
    }
}

}

and partial views like this :

<%@ Control Language=”C#” Inherits=”System.Web.Mvc.ViewUserControl” %>

Foo:

Bar:

<%@ Control Language=”C#” Inherits=”System.Web.Mvc.ViewUserControl” %>

Foo:

Bar:

I am always getting values set by controller actions. I want to set values in view and pass to partial view. How can I do this ?

Answer 1

Assuming you have a view model

public class MyViewModel
{
    public string Foo { get; set; }
    public string Bar { get; set; }
}

and a controller:

public class FooController: Controller
{
    public ActionResult Partial1(string id)
    {
        // TODO: use the id to fetch the model from somewhere
        MyViewModel model = ...
        return View(model);
    }

    public ActionResult Partial2(string id)
    {
        // TODO: use the id to fetch the model from somewhere
        SomeOtherViewModel model = ...
        return View(model);
    }

}

a corresponding partial view:

<%@ Control 
    Language="C#" 
    Inherits="System.Web.Mvc.ViewUserControl<AppName.Models.MyViewModel>" 
%>
<div>Foo: <%= Html.DisplayFor(x => x.Foo) %></div>
<div>Bar: <%= Html.DisplayFor(x => x.Bar) %></div>

and finally in your main view you could have a link:

<%= Html.ActionLink(
    "click me", 
    "Partial1", 
    "Foo", 
    new { id = "123" }, 
    new { id = "mylink" }
) %>
<div id="resultpartial1" />

which could be AJAXified:

$(function() {
    $('#mylink').click(function() {
        $('#resultpartial1').load(this.href);
        return false;
    });
});

Now of course if the id parameter is known only with javascript you could do this:

<%= Html.ActionLink(
    "click me", 
    "Partial1", 
    "Foo", 
    null, 
    new { id = "mylink" }
) %>

and then:

$(function() {
    $('#mylink').click(function() {
        $('#resultpartial1').load(this.href, { id: 123 });
        return false;
    });
});

UPDATE:

And for the second link:

<%= Html.ActionLink(
    "click me second link", 
    "Partial2", 
    "Foo", 
    new { id = "123" }, 
    new { id = "mysecondlink" }
) %>
<div id="resultpartial2" />

and then:

$(function() {
    $('#mysecondlink').click(function() {
        $('#resultpartial2').load(this.href, { id: 123 });
        return false;
    });
});
