Question

If, on a WPF window, you have more than 1 {Binding} for a parameter, is it possible to name them ?

For example for images i have (in the XAML part): Visibility="{Binding}" but also on some textboxes i want to make IsEnabled="{Binding}"
Is there some way to name them ? So that in the code in the backside (.cs side) it will pick the right one ?

Thanx in advance.

You can simply have view model wrapping those properties into single object:

public class ViewModel : INotifyPropertyChanged
{
    private bool imagesVisibility;
    private bool isTextBoxEnabled;

    public event PropertyChangedEventHandler PropertyChanged;

    public bool ImagesVisibility
    {
        get { return this.imagesVisibility; }
        set
        {
            this.imagesVisibility = value;
            this.PropertyChanged(this,
                new PropertyChangedEventArgs("ImagesVisibility"));
        }
    }

    public bool IsTextBoxEnabled
    {
        // ... similar as with ImagesVisibility property implementation
    }
}

Note that you’ll also need a boolean to visibility converter, which examples of you can find on StackOverflow (here)… or elsewhere.

Then, you simply set instance of ViewModel to your form data context:

public MyForm()
{
    InitializeComponent();
    DataContext = new ViewModel();
}

You can then do images binding like Visibility="{Binding ImagesVisibility}" and textbox IsEnabled="{Binding IsTextBoxEnabled}".
