c# - Overriding the combobox events -

Is this what I am doing wrong: - Firstly I created a square in heritage from Cambodia and I override some events Here's something like this:

  Public override zero selectedIndex changed (object sender, eventarges e)  

But it tells me: There is no appropriate way to override this "

thanks

To Override. But [EventName] methods are such that increase incidents. You should override that method, additional things you want to do, and then call base. The option to choose (e) when you want to increase this phenomenon:

  protected override zero-on-selected indices changed (EventErgues E) {// Additional accessories are the basis here. Select select (e); // Perhaps you want to do something after the event // has been implemented as the handler too)
