Asp.net-mvc – asp.net mvc Ajax.BeginForm

ajax.beginformasp.net-mvc

I'm having some difficulties with Ajax.BeginForm

I have something like this in a view

  <% using (Ajax.BeginForm("ActionName", null , null, new { id = "FormName" }))
     {%>
      <input type="hidden" value = '<%= Html.Encode( Model.id) %>' name="id"/>
      <textarea id="message" name=message rows="4" style="width: 90%"> 
      </textarea>
  <% }%}

And the action method is something like this

    [AcceptVerbs(HttpVerbs.Post)]
    [Authorize]
    public ActionResult ActionName(int id, string message)
    {
     ....
    }

I'm trying to pass the 'id' and 'message' to the action method. I'm passing 'null' for routeValues but I dont know what to pass. Ideally I was trying to find an overload that did not require route values but took actionName and htmlattributes (for form name) but I could not find one.I don't want to add 'message' to the view-model and I do need the FormName in there for jquery operations.
What is the best way to work around this problem ?

Oh, I forgot to mention, This is how I post the form

 $.post($("#FormName").attr('action'), $("#FormName").serialize(),
                               function(result) {
                                   $("#correspondingDiv").html(result);
                               }
                            );

Best Answer

Use this overload: http://msdn.microsoft.com/en-us/library/dd470605.aspx

Ajax.BeginForm(
    string "ActionName",
    string "ControllerName",
    new routevalues {id="IDValue",message="MyMessage"},
    new AjaxOptions {OnBegin=[someFunction], OnFailure=[failureFunction] },
    new { id = "FormName" }
)

Asp.net-mvc – Compile Views in ASP.NET MVC

From the readme word doc for RC1 (not indexed by google)

ASP.NET Compiler Post-Build Step

Currently, errors within a view file are not detected until run time. To let you detect these errors at compile time, ASP.NET MVC projects now include an MvcBuildViews property, which is disabled by default. To enable this property, open the project file and set the MvcBuildViews property to true, as shown in the following example:

<Project ToolsVersion="3.5" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <MvcBuildViews>true</MvcBuildViews>
  </PropertyGroup>

Note Enabling this feature adds some overhead to the build time.

You can update projects that were created with previous releases of MVC to include build-time validation of views by performing the following steps:

Open the project file in a text editor.
Add the following element under the top-most <PropertyGroup> element: <MvcBuildViews>true</MvcBuildViews>
At the end of the project file, uncomment the <Target Name="AfterBuild"> element and modify it to match the following:

<Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
    <AspNetCompiler VirtualPath="temp" PhysicalPath="$(ProjectDir)\..\$(ProjectName)" />
</Target>

C# – How to create a dropdownlist from an enum in ASP.NET MVC

For MVC v5.1 use Html.EnumDropDownListFor

@Html.EnumDropDownListFor(
    x => x.YourEnumField,
    "Select My Type", 
    new { @class = "form-control" })

For MVC v5 use EnumHelper

@Html.DropDownList("MyType", 
   EnumHelper.GetSelectList(typeof(MyType)) , 
   "Select My Type", 
   new { @class = "form-control" })

For MVC 5 and lower

I rolled Rune's answer into an extension method:

namespace MyApp.Common
{
    public static class MyExtensions{
        public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
            where TEnum : struct, IComparable, IFormattable, IConvertible
        {
            var values = from TEnum e in Enum.GetValues(typeof(TEnum))
                select new { Id = e, Name = e.ToString() };
            return new SelectList(values, "Id", "Name", enumObj);
        }
    }
}

This allows you to write:

ViewData["taskStatus"] = task.Status.ToSelectList();

by using MyApp.Common
