Hi I need to increase my property value every 500ms IF button is pressed/down.

Here is example code snippet

XAML

<Button Height="50" Width="100" Content="PressMe" MouseDown="Button_MouseDown"></Button>

private void Button_MouseDown(object sender, MouseButtonEventArgs e)
       {
           Value = Value + 1;
           System.Threading.Thread.Sleep(500);
       }

The problem is that my event never fires up. If I create mouseClick event in xaml it fires up, but doest fit my needs.

Hope you got my idea :)

Cheers!

Do you mean you want your value to be continuously increased once the button is pressed, every 500ms or just once with single pause of 500ms?

You probably need to create a thread on the ButtonDown event, and abort that thread on the ButtonUp event.

The thread will sit/spin until aborted, and every 1/2 second (or the interval you specify), the target value is increased.

If it were me, I'd use a BackgroundWorker object as my thread processing because it's easily cancellable from outside the object.
