I have a RadExpander on a UserControl. The datacontext of the UserControl (and therefor of the RadExpander) is bound to the selecteditem of a RadDataGrid (a list/details solution).The datacontext is a viewmodel and all my viewmodels implements INotifyPropertyChanged.
The first time I select an item in my datagrid, it goes well. After that, the pink textblock shows the previous Name (string) while the green shows the current.
That seems like a bug to me.
I cant just use the green one, because in my real solution I need to do complex stuff with datatriggers, but this is what it boils down to.
Here is the XAML, and I have attached a picture from my running program:
