How to disable click event temporarily of a panel (in Windows Forms app)?

Question

When I click on my panel a long computation starts and it last for some seconds. During this time I want to disable click event becuse if I don't the events accumulate in the event queue and finally they are served according FIFO one after the other. I want to avoid this I want to disable event queue whilst the first event is serviced. How can I do that?

This line will disable the Click event of a panel panel1 say whose Click handler is called panel1_Click: panel1.Click -= panel1_Click; and this will re-enable it: panel1.Click += panel1_Click;
