Manipulating event button in various formats

Question

Good guys, I’m trying to make a manipulation at the event button, in several forms different, I’m using C# WindowsFormAplication.

Well, I will try to say my logic here (I hope you understand).

I have a small system, it has T_Principal (see img below):

Note that on this same screen has 2 Icon, the first blank, another a floppy disk.

I added to them the event click.

My doubt is really in this part now, see the image below:

As you can see, man Form T_Agendamentos this one inside T_Principal.

I want to register events, which when clicking on the floppy disk triggers the event, check which form is triggering the event and executes the registration code. You can do this?

Answer 1

In fact T_Agendamentos is not in, is in front of T_Principal, so much so that it has the close buttons, minimize. If you open T_Agendamentos.ShowDialog() it will not let you click on the back window which is where the floppy disk is, have to use T_Agendamentos.Show().

Much more practical is if the floppy disk can stay on T_Agendamentos. The new window collects the data and sends it to the main archive. But suppose this is not an option...

If your classes call T_Principal and T_Agendamentos.

In T_Principal

using System.Windows.Forms;

namespace WindowsFormsApplication2
{
    public partial class T_Principal  : Form
    {
        public T_Principal()
        {
            InitializeComponent();
        }

        // Variável que guardará a referência da janela T_Agendamentos
        public T_Agendamentos JanelaAgenda;        

        // Abrir janela de cadastro
        private void NovoCadastro_Click(object sender, System.EventArgs e)
        {
            this.JanelaAgenda = new T_Agendamentos();
            JanelaAgenda.Show();
        }

        // Ícone do disquete clicado. Obter dados preenchidos
        // em T_Agendamentos e cadastrar
        private void Salvar_Click(object sender, System.EventArgs e)
        {
            string agendamento = null;
            string data = null;
            string solicitante = null;
            string local = null;

            // Esse método preenche as quatro variáveis
            this.JanelaAgenda.Cadastrar(ref agendamento, ref data,
                ref solicitante, ref local);

            // Código que faz o cadastro...
        }
    }
}

And in T_Agendamentos

using System.Windows.Forms;

namespace WindowsFormsApplication2
{
    public partial class T_Agendamentos : Form
    {
        public T_Agendamentos()
        {
            InitializeComponent();
        }

        // Método que passará para T_Principal os dados dos campos preenchidos
        public void Cadastrar(ref string Agendamento, ref string Data,
            ref string Solicitante, ref string Local)
        {
            // No caso as variáveis estão sendo passadas por referência,
            // preencher aqui é o mesmo que preencher de onde o método está sendo chamado
            // Basta passar os dados que foram preenchidos
            Agendamento = "Campo 1";
            Data = "Campo 2";
            Solicitante = "Campo 3";
            Local = "Campo 4";

            this.Close(); // Fecha a janela de cadastro
        }
    }
}

Answer 2

I do not know if it comes to the case, but beyond what proposed by Marcelo Nascimento, you can also create a delegate that receives a parameter that is your form trigger, take this parameter and fire the method relative to the form that triggered the event. It’s just one more option.
