Chapter 7 - Navigation: TreeView Control Question
Can the TreeView control ONLY be used for navigation? It looks like a great tool for item selection scenarios similar to a checkbox list or radio button list.
Is it possible to adapt it for use as a parent-child node list of checkbox items?
For example, let's say I wanted to traverse many GM vehicles and pick some. The top node would be GM.
GM
---Chevy
------Volt
------Impala
------Cruze
---Buick
------Regal
------Enclave
------Lacrosse
---Cadillac
------Escalade
------CTS
If I checked the GM box, it would select all vehicles. If I checked Chevy, it would select all Chevy's. Alternatively, I could select just individual car models if I wanted.
Could this control be used in that way? I've experimented a bit with it to show the check boxes, but don't know if itwould be the best way to offer a nested selection list.
Thanks so much,
WebDev

Reason: If anyone searches for treeview control, control was misspelled in title.

Hi there,
Yes, it can, although it doesn't support all the behavior you describe out of the box. I see two solutions:
1. Server side: on the CheckChanged of an item, post back to the server, loop over the child items and check / uncheck them.
2. Client side; do something similar but use jQuery to do all of this client side without a post back.
I don't know of any articles that describe this right away, but I am sure Google knows more.
Cheers,
Imar

Excellent - #1 was what I was working on, but wanted to see if I was heading down a dead end or not. Thanks. BTW, the way it's presented in the book, it appears as soley a naviagtion control.

Nope; the new one will be a new book on its own, without a list of what's new compared to the previous edition.
Cheers,

It's about ASP.NET 4.5.1 and VS 2013, again covering C# and VB.NET like in the current version.
Cheers,
Imar
