Things developers face while programming: We have seen rapid clicking on a button invoking the same event or the same process many times. Here we will find a way to control the rapid click error of a button.

We can write a class named SingleClick, in which we will write a method, Click with Object and EventArgs, as arguments to do the magic. Refer to the below code snippet for more.

  1. public class SingleClick
  2. {
  3. bool hasClicked;
  4. #region Button Click
  5. Action < object, EventArgs > _setClick;
  6. public SingleClick(Action < object, EventArgs > setClick)
  7. {
  8. _setClick = setClick;
  9. }#endregion Button Click
  11. public void Click(object s, EventArgs e)
  12. {
  13. if (!hasClicked)
  14. {
  15. _setClick(s, e);
  16. hasClicked = true;
  17. }
  18. Reset();
  19. }
  20. async void Reset()
  21. {
  22. await Task.Delay(800);
  23. await Task.Run(new Action(() => hasClicked = false));
  24. }
  25. }
Usage :
  1. var button = new Button();
  2. button.Clicked += new SingleClick(Button_Clicked).Click;
Try this workaround and give me your valuable suggestions. Happy Coding.
