C # Are you missing a usage directive or assembly reference?

Question

This error message appeared during compilation after I removed all the code for the behavior of the tabPage1_Click event.

It had no body code, because I accidentally clicked on it quickly twice, and the event code was added to the source when I just started programming the application. Now I'm done, and all the tops are tops, except that the useless definition is tabPage1_Click.

Error 1 "Bar.placeOrderForm" does not contain a definition for "tabPage1_Click", and the extension method "tabPage1_Click" cannot be found that takes the first argument of the type "Bar.placeOrderForm" (do you miss the use directive or build link?) C: \ admin \ Bar \ Bar \ placeOrderForm.Designer.cs 96 67 Bar

Answer 1

Go to the constructor for your placeOrderForm form, select tabPage1 from the list of fields in the Properties window, select the Events view, and simply clear the entry (read tabPage1_Click) in the Click event.

Must see you right.
