The Companies and Employees nodes both load fine. For the first level all I see is "Projects". The Builders and Projects under them don't appear. I'm guessing my HierarchicalDataTemplate is wrong but I can't see it. Anyone see what's wrong?
Eventually the Category will be styled like a colored block, and the items will be hyperlinks. They're two entirely different classes. This isn't a problem with a treeview and I've done it before. Just can't figure out why I't not working here.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
First of all, I'm not searching for tab virtualization.
1) The application is according to the mvvm architecture that I wish to maintain.
2) The application have 2 tabs "Tab 1" and "Tab 2" (tabcontrol) that we used tab caching followed by the solution of ikriv: WPF TabControl: Turning Off Tab Virtualization
3) Within "tab 1" stays general info.
4) Within "tab 2" stays left side the navigation and right side the content like the picture here : Sample picture
Clicking on"Inbox" and "Outbox" shows usercontrols on the right side.
On both Usercontrols stays an label with an textbox where I applied databinding for the saved state
The situation now: When I switch from "Tab2" Inbox item where i filled in the textbox "100" as example to tab 1. It works like a charm, when switching back to the inbox my value "100" is saved with thanks to the solution of ikriv.
The problem: When I switch from "Tab2" Inbox to another item within Tab2 like "Outbox" and switching back the data is lost. The value of "100" is gone. It will be resetted to "0"
The Inbox / Outbox/ .. items like in picture are not tabs but the NavBarControl from DevExpress.
The problem is when switching by the items of the control of devexpress.
