I have a method to detect the left click event that visual studio made by double clicking on the form private void pictureBox1 Click object sender EventArgs e MessageBox Show Left click I want to have a right-click event by right-clicking on the same object I read online that you can use this switch private void pictureBox1 Click object sender EventArgs e if e Button System Windows Forms MouseButtons Right MessageBox Show Right click if e Button System Windows Forms MouseButtons Left MessageBox Show Left click The trouble is that when I do e Button it has has yields an error error System EventArgs does not contain a definition for Button So I fix this by changing the EventArgs e to MouseEventArgs e But then there is a new error in Form1Designer where the event line is this pictureBox1 Click new System EventHandler this pictureBox1 Click The error says No overload for pictureBox1 Click matches delegate System EventHandler How do I fix this Thanks for reading

How to get a right click mouse event? Changing EventArgs to MouseEventArgs causes an error in Form1Designer?

You should introduce a cast inside the click event handler

MouseEventArgs me = (MouseEventArgs) e;
