Is there a way to detect a side mouse button press in c# (For example, Mouse 5)?

without using any external libraries would be the best method, but it wont be the end of the world.

CodePudding user response：

Create on any control event method MouseDown. Second method arguments in this method will be MouseButtonEventArgs which has property ChangedButton.

ChangedButton is a mouse button that was pressed.

In your case side button 5 will be XButton2.
