@GeertvanHorrik If I'm using TreeViews with a HierarchicalDataTemplate with Catel, what is the correct way to handle changes to "Expand" of each TreeViewItem preferrably in the ViewModel of the TreeViewItem? I tried "EventToCommand" Trigger but this doesn't work as it's bound to the TreeView as a whole not on TreeViewItem level. Then I tried using a Style Setter (<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />) but this binds to the Model behind the TreeViewItem directly instead of ViewModel. Any hints?
Thanks for the hint. I'm not sure if I completely understand what you're saying. Is your comment about binding to "TreeListView.DataContext" refering to EventToCommand Trigger or to the Property Setter I was describing? Could you maybe send a short code snippet of what exactly you mean?
I'm not talking about an example, I just didn't understand what you meant by "try to use x:Name and bind to TreeListView.DataContext" and thought you could tell me in which context I need to read your answer to understand correctly. Can of course also try on StackOverflow - however most of the Catel questions that have real "solution" there where also answered by you ;)
I just tried to implement a wizard according to the manual in https://opensource.wildgums.com/orc.wizard/ but there is a problem I can't resolve. I get the "System.MissingMethodException" which is missing "Void catel.Data.ModelBase.SetValue(Catel.Data.PropertyData, !!0, Boolean)". When I try to "LoadAssempliesOnStartup" within FodyWeavers, I get the error that it fails to execute weaver "LoadAssembliedOnStartup.Fody.dll"
Is there something I can do to solve this?
note that it's best to let nuget fight out all dependencies, and we totally recommend you to use the latest alpha of Orc.Wizard since that will be released very soon
Oh yes, this was the problem. I updated all packages according to the dependencies and it seems to work. The wizard window is damn small, in the output the error is that a ThemeManager is not initialized. I did not find any information about a theme manager, the only thing I found is the this.ApplyTheme() in Orc.Wizard.Example
And you can control the size of the wizard from within the wizard model
or use the AccentColor / BaseColorScheme methods and it should auto-apply it for you
a wizard page has a Wizard property, and that contains all the wizard pages available inside the wizard (including the state).
In the example wizard, you can see how the summary page uses all other pages to determine the summary at the end
LogManager.AddDEbugListener(true) or something like that
It is now MyWizard(Parameter, ITypeFactory typerFactory) : base(typeFactory) - what a bad mistake
This is example in doc,but it is incorrect
if you want, you can contribute to the docs with a fix :)

ConfigurationService GetValue custom type does not get the expected result
Any ideas why after updating Catel to version 5.12.7 I get error: "Cannot add instance of type 'EventToCommand' to a collection of type 'TriggerActionCollection'. Only items of type 'T' are allowed.", while I try to use EventToCommand? Before update it worked flawlessly. It must be something with dependencies versions, but I have no clue what has changed.
Since I updated my package versions, I can't bind a collection to a ListBox anymore. I get the error that the "collection must be empty before using ItemsSource". This has never been a problem before. It seems that I can't CreateInstanceWithParametersAndAutoCompletion and pass one of the parameters to a binding Object anymore. When the _uiVisualizerService.ShowDialogAsync is called, the error is thrown when using a ListBox
