CTL-47: Rebind view with ViewModel in tabcontrol about catel HOT 11 CLOSED

Comment created by @GeertvanHorrik:

No, posting it here is preferred. Jira provides much better workflow handling and much more than codeplex does.

I can reproduce the behavior in your app. Now trying to see why it happens.

It's strange that the actual DataContext of the SettingsWindow is the view model. The DataContext should remain nothing, the inner grid datacontext should be the SettingsViewModel. Maybe it has to do with the fact that these are data templates. Still figuring out.

Comment created by @GeertvanHorrik:

Yes, that is the issue. They are DataTemplates and are selected based on their datacontext. The SelectedItem is the CurrentViewModel which then works a bit different.

It is best to simply create 2 tabs with different views and let the views take care of the view model construction.

To fix this, please use the following steps:

1. Clear all code-behind in MainWindowViewModel

2. Change your MainWindow xaml to:

    <TabControl >
        <TabItem Header="{Binding RelativeSource={RelativeSource Self}, Path=Content.ViewModel.Title}">
            <views:HomeWindow />
        </TabItem>
   
        <TabItem Header="{Binding RelativeSource={RelativeSource Self}, Path=Content.ViewModel.Title}">
            <views:SettingsWindow />
        </TabItem>
    </TabControl>

Do you meaning this case has been fixed?
Actually, I have same issue. My case is first tab is list data, when i click one of this list, program should create new tab with selected item data, since tab item added base on click, I can't pre-set tabitem.
Could you give me some suggestion?

Environment:
.NET 4.0, VS2010, Catel 3.9

It was a bug in the user code. Try using the 2 hints I gave in my last comment.

beside this option, any another idea?
I would like locate viewmodel first then get view,
it looks you release view everytime when I switch to another tabitem, but when switch back new view lost binding.

Comment created by @GeertvanHorrik:

The TabControl provided by Catel (see Catel.Extensions.Controls) has several different options to control the behavior. If you think you found a bug in the latest prerelease (note we fixed a lot from 3.90 => current state), please provide a repro.
