Binding-Error with ListBoxItem style

See original GitHub issue

Hello,

there is a issue with the properties “HorizontalContentAlignment” and “VerticalContentAlignment” in conjunction with the ListBoxItem style. This is the error message which is shown in the Output-Window:

error

This error occurs if the ItemsSource of the ListBox is binded to a ObservableCollection an their elements change. The error message is not displayed when I do the following:

<Style TargetType="{x:Type ListBoxItem}" BasedOn="{StaticResource {x:Type ListBoxItem}}"> <Setter Property="HorizontalContentAlignment" Value="Left" /> <Setter Property="VerticalContentAlignment" Value="Top" /> </Style>

But that is not a good solution. I hope that this bug will be corrected. Thanks! 😃

Sorry for my bad English. 😄

Uploading sample project for historical reference. MaterialDesignInXamlToolkit_922-main.zip

I was planning on attaching a ZIP after I thought this issue is resolved (and I delete that repo). I thought you prefered a GitHub repo like that over an attached ZIP since the new issue template says

Seriously consider creating and linking to a test repo which takes absolutely minimal setup to illustrate how reproduce the problem.

My time is limited and .Zip files, code snippets and partial examples are often a time sink. GitHub also provides great communication and code review tools which can be utilised. … Post a full GitHub repository. Not a zip file, half baked snippet etc. …

Sorry for not also attaching a ZIP of the MWE.
