I have a WPF application. There is a listview in which a every time I click or double click, the click event fires up. Even if I keep the Click Event, it automatically fires up when I Double click it. And if I bind the action in DoubleClick, it won't work in single click.
How can I handle both separately?
Add a handler to your control:
<SomeControl MouseDown="MyMouseHandler">
...
</SomeControl>
The handler code:
private void MyMouseHandler(object sender, MouseButtonEventArgs e)
{
if (e.ClickCount == 2)
{
//Handle here
}
}
The second click of a double-click is by definition always preceded by a single click.
If you don't want to handle it you could use a timer to wait for like 200 ms to see if there is another click before you actually handle the event:
public partial class MainWindow : Window
{
System.Windows.Threading.DispatcherTimer _timer = new System.Windows.Threading.DispatcherTimer();
public MainWindow()
{
InitializeComponent();
_timer.Interval = TimeSpan.FromSeconds(0.2); //wait for the other click for 200ms
_timer.Tick += _timer_Tick;
}
private void lv_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if(e.ClickCount == 2)
{
_timer.Stop();
System.Diagnostics.Debug.WriteLine("double click"); //handle the double click event here...
}
else
{
_timer.Start();
}
}
private void _timer_Tick(object sender, EventArgs e)
{
System.Diagnostics.Debug.WriteLine("click"); //handle the Click event here...
_timer.Stop();
}
}
<ListView PreviewMouseLeftButtonDown="lv_PreviewMouseLeftButtonDown" ... />
Please try following code snippet:
if (e.ChangedButton == MouseButton.Left && e.ClickCount == 2) {
// your logic here
}
