Question

I have a control with a dependency property which I want to pass which is a property in a class, and I also want to use an ObservableCollection which part of that class as the datacontext for that control.

<mycontrols:News 
   feedStatus="{Binding newsData.newsStore.feedStatus}" 
   DataContext="{Binding newsData.newsStore.news}"
/>

The problem here is that the DataContext is used when it evaluates {Binding newsData.newsStore.feedStatus} how can I get it to pass feedStatus first and then set the DataContext.

I would use just the single datacontext if silverlight had the ability to back track up the datacontexts parent, but I don’t think this is the case.

Could I set datacontext as a nested parameter?

Answer 1

Set the DataContext to DataContext="{Binding newsData.newsStore} and then bind the feedStatus and news properties inside your UserControl.

Alternatively use multiple dependency properties, instead of the DataContext.

Also, please use .NET naming conventions (PascalCase!). Java style casing makes my eyes cringe.
