WPF数据选择器选定的日期更改事件处理程序

Question

I am trying to add an event handler to a date picker control programmatically during the window load process, but it is giving me an error message:

Cannot implicitly convert type 'System.Windows.Controls.SelectionChangedEventHandler' to 'System.EventHandler'

The code:

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            LoadCombo();
            dpFrom.SelectedDateChanged += new SelectionChangedEventHandler(this.dp_SelectedDateChanged);

        }

private void dp_SelectedDateChanged(object sender, SelectionChangedEventArgs e)
{
   // reset label;                    
}

Answer 1

Just try the short form (syntactical sugar):

dpFrom.SelectedDateChanged += this.dp_SelectedDateChanged;

(this is usually automatically generated when coding in Visual Studio)
