How to remove event handler codes

Question

When I try to delete those empty handlers the form gets broken. How can I remove those annoying codes from my program without affecting form?

Could you add this code here as a snippet, not a screenshot? — ssuperczynski

When you delete the btnOrder_Click you should also delete the following line in yourForm.Designer.cs:

this.btnOrder.Click += new System.EventHandler(this.btnOrder_Click);

To find this line after you removed the btnOrder_Click rebuild your project and then in the Error List window double click on error which says:

'WindowsFormsApplication1.Form1' does not contain a definition for 'btnOrder_Click' and no extension method 'btnOrder_Click' accepting a first argument of type 'WindowsFormsApplication1.Form1' could be found (are you missing a using directive or an assembly reference?)

By double clicking on this error you will redirect to that line and after deleting that line your form returns back.

This technique is called "Leaning on the compiler" and I'm a fan of it :) +1

Also from Properties window: events tab > right click on event > reset

This is why it is annoing to hear people say: NEVER EDIT THE DESIGNER FILE MANUALLY! If you have deleted the event handler in the .cs file, you have to manually delete the rest in the designer file.
