Jquery – Using AJAX with ASP.NET MVC 1.0 on IIS 6

asp.net-mvciis-6jquery

I am running into a problem trying to use AJAX and jQuery with ASP.NET MVC on IIS 6.0. I receive a 403.1 error when I attempt to invoke an action via jQuery. Is there anything I must add to the web.config in order to support this?

Client Code

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

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

<script type="text/javascript">
    function deleteRecord(recordId) {
        // Perform delete
        $.ajax(
        {
            type: "DELETE",
            url: "/Financial.mvc/DeleteSibling/" + recordId,
            data: "{}",
            success: function(result) {
                window.location.reload();
            },
            error: function(req, status, error) {
                alert("Unable to delete record.");
            }
        });
    }


</script>

<a onclick="deleteRecord(<%= sibling.Id %>)" href="JavaScript:void(0)">Delete</a>

Server Code

[AcceptVerbs(HttpVerbs.Delete)]
public virtual ActionResult DeleteSibling(int id)
{
    var sibling = this.siblingRepository.Retrieve(id);
    if (sibling != null)
    {
        this.siblingRepository.Delete(sibling);
        this.siblingRepository.SubmitChanges();
    }

    return RedirectToAction(this.Actions.Siblings);
}

Error

You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed.

HTTP Error 403.1 – Forbidden: Execute access is denied.
Internet Information Services (IIS)

Update

Darin correctly pointend out that it helps if you add the DELETE verb to .mvc extension, however I an now running into the following issue:

[HttpException (0x80004005): Path 'DELETE' is forbidden.] System.Web.HttpMethodNotAllowedHandler.ProcessRequest(HttpContext context) +80 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication+IExecutionStep.Execute() +179 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Status: 405 – Method not allowed

Best Answer

When you register the .mvc extension with aspnet_isapi.dll in IIS you need to enable the DELETE verb:

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
