This is ridiculous. I have a KeyDown event I am interested in(to get DownArrow Key event) for a WinForm. I added a trackbar, which gets Autofocus(I dont know how). And now, when I press the DOWN arrow key - it automatically changes the value of the Trackbar and my code for the Winform is not working. I tried HIDING the Trackbar with a button but to no avail. I even have 

e.SuppressKeyPress = true;

in my Form1_KeyDown() handler.

Help, I am going haywire.

You can override ProcessCmdKey method. check out below links for more information.

Up, Down, Left and Right arrow keys do not trigger KeyDown event

  • unfortunately, UP|DOWN|LEFT|RIGHT /are/ triggering KeyDown() events, and they're being consumed by Trackbar. I found a solution around it. It is to Override KeyDown() event for the trackbar and call Form1_KeyDown() event instead. – Aniket Inge Sep 22 '12 at 15:46
  • Have you checked with ProcessCmdKey() method? if you pressed any key on form this method will execute if you override it in your form codebehind file. – Jignesh Thakker Sep 22 '12 at 15:53
