Xamarin - Toolbaritems

Question

In the application I have 2 Toolbaritem items (ToolbarItem Name="Digitar" Activated="Digitar" ToolbarItem Name="Procurar" Icon="procurar48.png" Activated="Procurar"), the first is a word and the second is a magnifying glass. What I want to do is when I click on the magnifying glass make the magnifying glass invisible and enable the space of the word to enter the searched item. It’s a very simple thing but in Xamarin it’s a lot of work.

My code . Cs

   private void Procurar(object sender, EventArgs e)
    {
        ToolbarItems.Remove(Digitar);
    }

It turns out that this way is giving error in the word Type(It is not possible to convert from "group of methods" to "Toolbaritem"
