' check subtitle exists, if so, build menu, loop though subtitles somehow?
if not IsDBNull(reader.Item("subtitle"))
mydata = "<ul>"
mydata &= "<li>" & reader.Item("subtitle") & "</li>"
mydata &= "</ul>"
end if

Web Forms :: Put Multilevel Navigation Structure (from A Database) Into The Menu - Control
Jul 23, 2010In classic ASP I would write some logic to get a nice menu on the site, but now with the Menu-control, it's as easy as it gets.. Maybe to easy. I can't quite figure out how I would do this.. I have a multilevel navigation structure (from a database) that I want to put into the Menu-control, but I don't know which approach is the best/easiest way for me..
I'm all into performance, usability and all that.. The only thing I have really decided is that I want to use the Menu-control, I haven't decided what datasource I should use or how to style the individual links my way The data is coming from a database and is not supposed to be changed very often (maybe once or twice every month).. Thought of making an XML-sitemap, but also of making some sort of SQL-hookup.. I'm leaning towards the XML-sitemap because it wouldn't take long to generate the XML every time the navigation changes and that won't happen very often. The next issue is styling, how to do that? I have the neccesary css ready for the individual links, but I'm still unsure of how to get it to the Menu-control.. The css I have looks like below and in its current form is intended just for the anchors

MVC :: Generate View With Loop And Metadata Class?
Feb 12, 2011I'n trying to setup a view template dynamically using a foreach loop. The view template is as follows:
[Code]....
My metadata class is as follows:
[Code]....
The partial seems to render the labels correctly, displying the appropriate name for the fiields that I have annotated. However the value of the fields is always set to the class property name itself rather than the value of the given record itself.Now I'm pretty sure my problem is something stupid, but I can't see what I am missing. I followed Brad Wilson's guide here adjusting it for Razor's syntax:http://bradwilson.typepad.com/blog/2009/10/aspnet-mvc-2-templates-part-4-custom-object-templates.html

Web Forms :: Dynamically Generate A Menu?
Nov 11, 2010I have a 3 layer aps.net application (DAL, BLL,PL)
I wanted to create a horizantal menu and then to populate/enable/disable the items of the menu depending on the user has permision of a specific form/page or not.
The backend/ data base work is complete. I give rights to a user/role on a specific page and I
also develope functions/procedures to check the user rights/retrieve all pages on which the user has rights.
The missing part is the front end, How I can implement this on the front end?
If I got some standard way, I will immplement it in all my future asp.net apps, As most of our apps have some menu and we want to display mentu items to the user depneding on the rights.
I may want to clear one thing here that I want a horizantal menu but there is no horizantal menu in aps.net tree view.
