Accessing Linq Values in ViewData
I'm having trouble accessing the id, area and theme values in my ViewData.
They are being set in my action filter but when I get to the Site.Master I don't have access to them.
Any hel开发者_运维技巧p or advice would be great.
ActionFilter
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
int SectionID = Convert.ToInt32(filterContext.RouteData.Values["Section_ID"]);
int CourseID = Convert.ToInt32(filterContext.RouteData.Values["Course_ID"]);
if (CourseID == 0)
{
filterContext.Controller.ViewData["Styles"] = (from m in _dataContext.Styles where m.Area_ID == SectionID select new {theme = m.Area_FolderName }).ToList();
}
else
{
filterContext.Controller.ViewData["Styles"] = (from m in _dataContext.Styles where m.Course_ID == CourseID select new { theme = m.Course_FolderName }).ToList();
}
}
}
Site.Master
<%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>
<%@ Import Namespace="Website.Models" %>
<%
foreach (var c in (IEnumerable<Styles>)ViewData["Styles"])
{
Response.Write(c.Theme);
}%>
Editting again based on your feedback...
I think you'd best be served by creating a ViewModel so that you can strongly type your View.
Create a class like the following (you can add fields as needed):
public class StyleViewModel
{
public string Id {get; set;}
public string Area {get; set;}
public string Theme {get; set;}
}
Then in your controller:
filterContext.Controller.ViewData["Styles"] =
(from m in _dataContext.Styles
where m.Area_ID == SectionID
select new StyleViewModel
{
Id = m.Area_ID
Area = m.Area_Name
Theme = m.Area_FolderName
}).ToList();
You can then clean up the code in your View:
<%
foreach (var c in Model)
{
Response.Write(c.Theme);
}
%>
