ASP.NET webforms physical site structure with dynamic site map

I am having a little difficulty trying to wrap my head around site structures. I have quite a large asp.net site, for which:

Admins can see a user list, Each user can have many accounts, and for each account can have many items.

I can picture this as a breadcrumb trail of editing a particular item.

User List > Mr Bob > Accounts > BOB77 > Items > Item32 > Edit

• User List = All the users
• Mr Bob = A user the administrator has selected from the User List
• Accounts = A list of the user's accounts
• 12BOB = The administrator has selected the account named 12BOB
• Items = A list of the items an account contains
• Item32 = The item that the administrator selected
• Edit = The action that the administrator wants to do

I can picture how this would look like if it was using ASP.NET MVC with the URL, but I am unsure how to map this out using Webforms, and in the physical filesystem.

This is what I have thought up about how I am guessing the physical structure would look like. Will this have to use session variables to achieve what I am trying to do?

• /Users/User/Edit.aspx <- for editing a user
• /Users/User/View.aspx <- for viewing a user
• /Users/User/Accounts/Default.aspx <- for viewing all accounts
• /Users/User/Accounts/Account/View.aspx <- for viewing an account
• /Users/User/Accounts/Account/Edit.aspx <- for editing an account
• /Users/User/Accounts/Account/Items/Default.aspx <- for viewing all items in an account
• /Users/User/Accounts/Account/Items/Item/Edit.aspx <- for editing an item

Where can I read more about this kind of setup in a web application? Or, can someone point me in the direction of an available project that has this kind of layout?

Thanks

This seems simple, but when you want to lay out the logical structure and you're considering every element to the structure, it becomes very unclear.

This is the url format I came up with. This uses query strings instead of Session variables. Query strings are used as parameters.

Using this format I was able to make a sitemap provider which interpreted the values of the querystring and replaced the names of nodes for that page.

• User/Edit.aspx?UserID=11111
• User/Account/Default.aspx?UserID=11111
• User/Account/Edit.aspx?UserID=111&AccountID=54353
• User/Account/Item/Edit.aspx?UserID=3333&AccountID=43243&ItemID=432432

I hope this helps you, if you are in a similar situation to what I was.
