I’m trying to write a program that uses tabs to hold different usercontrols. What I currently want to happen is the user clicks a find button, a new tab is created, and a find screen appears inside it. Using the find screen the user can select clients and these then open in their own new tabs allowing the user to edit them. So if the user went in and selected three clients, the screen would have four tabs, one for the find screen and three client tabs. It will also need to close the tab when the user clicks an exit button on the usercontrol in that tab.
My problem is that I’m not sure how to set this up in my program. I’ve created a TabControl and bound the ItemsSource to a collection of viewmodels (that I can add to whenever a user adds a new screen). I can use a DataTemplateSelector to select the DataTemplate that contains the right view, but I don’t know how to set the resource of the view to my viewmodel.
I’m doing this in WPF and I’m currently using Bxf to put my viewmodels into the views, and this normally works but I’m unsure how it fits in with the TabControl.
I’m trying to stick to MVVM so having a list of views in my viewmodel is out.
Has anyone done something similar to this before?
I’ve just answered my own question.
The tabitems that get created dynamically are set up with a datacontext of the individual item from the tabcontrols itemsource property, in this case one of my viewmodels.
The datatemplate I used correctly picks up the correct view for the viewmodel type and displays this.
However my view set the datacontext of the grid on the view to my resource and so nothing was showing up. I’ve changed this to use the datacontext instead of the resource and now everything is working.
So my main problem was having my views run off of resources and not the datacontext. I still would prefer to use resources but as datacontext works I’m going to have to go with that.
