问题 How can I bind 2 properties to a single TextBlock.Text (eg. first name and last name or current value and max value)? something like: // IValueConverter public object Convert( .... ) { return string.Format("{0} (max: {1})", currentValue, maxValue); } The problem is I want TextBlock.Text to be updated when currentValue or maxValue has changed.

问题 I'd like to be able to click a textblock and have it run a Command. Is this possible?
