Without seeing your code, I'm guessing your QuestionControlsState
class isn't implementing INotifyPropertyChanged.
Modify it like this:
public class QuestionControlsState : INotifyPropertyChanged
{
private bool isEnabled = true;
public bool IsEnabled
{
get { return isEnabled; }
set
{
isEnabled = value;
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs("IsEnabled"));
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
}
This will trigger a PropertyChanged event whenever you change the IsEnabled
property, notifying the view it needs to refresh.
Of course, if you're using the MVVM pattern, the correct way of doing this is binding all textboxes to a boolean IsEnabled property in the ViewModel and not by trying to find the static resource in codebehind... Then, a simple IsEnabled = false
in the VM will disable all textboxes (without the need of a staticresource)
