"The method or operation is not implemented" with 2013.1.319.340

[David A.]

Hi,

Just downloaded 2013.1.319.340 and am receiving the following error when using the menu:

"The method or operation is not implemented".

(StackTrace)

[NotImplementedException: The method or operation is not implemented.]

(rest omitted for brevity)

The code is as follows:

@(Html.Kendo().Menu()
 .Name("mn-case")
 .Items(items =>
 {
items.Add().Text("Dashboard").Action("Index", "Dashboard", new { caseId = caseId, area="Case" });
}))

The route is defined as follows:

context.MapRoute("CaseIndex",
               "Case/{caseId}/{controller}",
               new { action = "Index"},
               new RouteValueDictionary { { "httpMethod", new HttpMethodConstraint("GET") }}
               );

This did not happen in previous versions and the workaround is to use Url.Action as follows:

items.Add().Text("Dashboard").Url(@Url.Action("Index", "Dashboard", new { caseId = caseId, area="Case" }));

I have many projects that use the menu and do not want to have to change them all.  Is this a problem on my end or is it Kendo?

Thank you,
David Adams

Hello David,

 
Thank you for drawing our attention to this issue. Unfortunately, I was not able to replicate the issue locally and I will need a simple test project, which reproduces the problem. Thus I will be able to investigate the case locally and fix the issue.

As a side note, you can turn off security trimming functionality of the widget to avoid this:

@(Html.Kendo().Menu()
    .Name("menu")
    .SecurityTrimming(false)

Kind regards,

Thank you for your quick response Georgi.  The problem occurs when defining the route, specifically:

new RouteValueDictionary { { "httpMethod", new HttpMethodConstraint("GET") }}

Setting SecurityTrimming=false did work, but that is just a workaround for this project :).  It would be ideal if this could be fixed.

Here is a sample project demonstrating the error. http://sdrv.ms/ZfHEqI

Thank you,
David A.

Hello David,

 
Thank you for the test project. We was able to investigate the problem and to address it. The issue will be fixed in the next internal build of Kendo UI. I updated your Telerik points because of the involvement.

I have the same exception with a similar Stacktrace.

The version I currently use is 2013.1.514.340.

[Daniel]

Hello,

Most of the methods of the HttpRequestBase were added for the service pack. Could you provide the stacktrace or a runnable sample so I can check if we have missed some method or the reason for the exception is different?

This happens with the following use of Kendo Menu:

public static MvcHtmlString Menu(this HtmlHelper html)
        {
            IPrincipal user = html.ViewContext.HttpContext.User;

            var menuItems = new[]
            {
                new { Title = "Dashboard", Action = "Show", Controller = "Dash", RequiredRoles = AuthorizationService.PUBLIC_REQUIRED_ROLE, Order = 0},
                new { Title = "Dash-Konfiguration", Action = "Edit", Controller = "Dash", RequiredRoles = AuthorizationService.PUBLIC_REQUIRED_ROLE, Order = 1 },
                new { Title = "Benutzerrollen", Action = "Show", Controller = "Admin", RequiredRoles = AuthorizationService.ADMIN_ROLE, Order = 3 },
                new { Title = "Webservice", Action = "Show", Controller = "WebserviceAdmin", RequiredRoles = AuthorizationService.ADMIN_ROLE, Order = 2 }
            };

            var items = menuItems.Where(
                m => m.RequiredRoles.Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries)
                    .Any(
                        r => user.IsInRole(r) || r.Equals(AuthorizationService.PUBLIC_REQUIRED_ROLE, StringComparison.InvariantCultureIgnoreCase)
                        )
                    )
                .OrderBy(m => m.Order)
                .GroupBy(m => m.RequiredRoles)
                .ToDictionary(g => g.Key, g => g.ToList());

            string menuString = html.Kendo().Menu()
                .Name("menu")
                .Items(menuItemCollection =>
                    {
                        foreach ( var m in items[AuthorizationService.PUBLIC_REQUIRED_ROLE])
                        {
                            menuItemCollection.Add().Text(m.Title).Action(m.Action, m.Controller);
                        }

                        if (items.ContainsKey(AuthorizationService.ADMIN_ROLE))
                        {
                            menuItemCollection.Add().Text("Administration").Items(children =>
                            {
                                foreach (var m in items[AuthorizationService.ADMIN_ROLE])
                                {
                                    children.Add().Text(m.Title).Action(m.Action, m.Controller);
                                }
                            });
                        }
                    }
                )
                .ToHtmlString();

            return new MvcHtmlString(menuString);
        }

Hello,

Thank you for the additional information. It seems that the HttpMethod getter was missed in the service pack and was later added. Please try with the latest official release(Q2 2013) and let me know if the problem persists.

Thank you very much. The error is fixed with the new version.
