How can I invoke MouseDoubleClick event on Button code behind?
I've tried something like this:
btn.RaiseEvent(new RoutedEventArgs(Control.MouseDoubleClickEvent));
but when I do so I receive the following error:
Object of type 'System.Windows.RoutedEventArgs' cannot be converted to type 'System.Windows.Input.MouseButtonEventArgs'.
You need to use MouseButtonEventArgs in place of simple RoutedEventArgs :
Code-behind:
private void button_WithDoubleClick_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
MessageBox.Show("Double click");
}
private void button_RaiseDoubleClick_Click(object sender, RoutedEventArgs e)
{
var args = new MouseButtonEventArgs(Mouse.PrimaryDevice, 0, MouseButton.Left)
{
RoutedEvent = Control.MouseDoubleClickEvent
};
this.button_WithDoubleClick.RaiseEvent(args);
}
Xaml:
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Name="button_WithDoubleClick" Content="Button with double click" MouseDoubleClick="button_WithDoubleClick_MouseDoubleClick" />
<Button Grid.Row="1" Name="button_RaiseDoubleClick" Content="Button to raise double click" Click="button_RaiseDoubleClick_Click"/>
</Grid>
PS: I am not sure what shall be given as the value of the second constructor param for the MouseButtonEventArgs
- The time when the input occurred.
. 0 works well in this demo, but whether it will work with more complex interactions I do not know.
