R – Accessing SharePoint structure and user infpormation from ASP.NET

asp.netsharepointwindows

I am looking at ways of limiting data (pages) visible to users based on their SharePoint group memberships. One option is to run my site on it's own, determine group membership in code, and limit data available, and the other, less attractive option is to deploy my site to several departmental sites, and then determine which data to present according to the parent site that mine is hosted under.

In either case, I need to access some sort of SharePoint API to determine either the location of my site, or the group membership of the logged on user. How can I go about getting this information?

You don't need to do anything in code. Based on your description, you are trying to limit access to data on pages, based on their membership of a particular SharePoint group. Break the inheritance from the main site and just configure access for those in that SharePoint group...

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

R – Problem with Authorization and variations in Sharepoint

This is because variations aren't actual locations and so the web.config option won't work - they are a little url trick which defines what is read from the database.
