@jorgemaiadin : if (!Char.IsDigit(input) && input != 8 && input != 46 && input != 45)

Follow the code above. ASCII Character for negative is 45 so exempt it form validation as he did for back space and I also changed to accept decimal values with period . that has ASCII code as 46.

the error is

Error 1 'System.Windows.Forms.KeyEvent­Args' does not contain a definition for 'KeyChar' and no extension method 'KeyChar' accepting a first argument of type 'System.Windows.Forms.KeyEvent­Args' could be found (are you missing a using directive or an assembly reference?)
