Asp – Generate A-Z from ASP.NET SiteMap

asp.netsitemap

I wish to generate an A-Z from a SiteMap… I do not use the Web.SiteMap directly, rather a StaticSiteMapProvider, based on this blog post by Simon Harriyott: Adding dynamic nodes to ASP.NET site maps at runtime by deriving from StaticSiteMapProvider

How can I go about doing this?

Edit:

I want an A-Z list, by link title. Could be starting at the root node or any child node. I also want to bind to a repeater and limit which pages to show (for example, don't show links with 'admin' or 'profile' in the URL).

Using .NET 2.0, so no LINQ code.

I'm not exactly sure what you mean by an "A-Z". I think what you mean is you want an alphabetized list of all pages in your SiteMap? If so then this might help.

        var NodesAtoZ = from SiteMapNode node in SiteMap.RootNode.GetAllNodes()
                    orderby node.Title
                    select new
                    {
                        Title = node.Title,
                        Url = node.Url,
                        Description = node.Description
                    };

This returns a list of all SiteMap nodes ordered by Title.

Asp.net-mvc – A potentially dangerous Request.Form value was detected from the client

I think you are attacking it from the wrong angle by trying to encode all posted data.

Note that a "<" could also come from other outside sources, like a database field, a configuration, a file, a feed and so on.

Furthermore, "<" is not inherently dangerous. It's only dangerous in a specific context: when writing strings that haven't been encoded to HTML output (because of XSS).

In other contexts different sub-strings are dangerous, for example, if you write an user-provided URL into a link, the sub-string "javascript:" may be dangerous. The single quote character on the other hand is dangerous when interpolating strings in SQL queries, but perfectly safe if it is a part of a name submitted from a form or read from a database field.

The bottom line is: you can't filter random input for dangerous characters, because any character may be dangerous under the right circumstances. You should encode at the point where some specific characters may become dangerous because they cross into a different sub-language where they have special meaning. When you write a string to HTML, you should encode characters that have special meaning in HTML, using Server.HtmlEncode. If you pass a string to a dynamic SQL statement, you should encode different characters (or better, let the framework do it for you by using prepared statements or the like)..

When you are sure you HTML-encode everywhere you pass strings to HTML, then set ValidateRequest="false" in the <%@ Page ... %> directive in your .aspx file(s).

In .NET 4 you may need to do a little more. Sometimes it's necessary to also add <httpRuntime requestValidationMode="2.0" /> to web.config (reference).

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
