[C#/Windows Form Application] User controls

[fenomeno83]

Venendo al tuo problema, non fai prima a lasciare i controlli sempre lì, ma mostrarli/nasconderli alla bisogna?

Grazie!
DIci una cosa del genere?

Dentro il form principale:

public Tool()
{
            InitializeComponent();
            MainPanel.Controls.Add(Global.Login = new Login());
            MainPanel.Controls.Add(Global.UserControl1= new UserControl1());
            MainPanel.Controls.Add(Global.UserControl2= new UserControl2());
            MainPanel.Controls.Add(Global.UserControl3= new UserControl3());


            Control[] lg = MainPanel.Controls.Find("Login", true);
            Control[] ch = MainPanel.Controls.Find("UserControl1", true);
            Control[] ns = MainPanel.Controls.Find("UserControl2", true);
            Control[] es = MainPanel.Controls.Find("UserControl3", true);
            lg[0].Visible = true;
            ch[0].Visible = false;
            ns[0].Visible = false;
            es[0].Visible = false;
 }

Dentro lo usercontrol Login:

private void btnLogin_Click(object sender, EventArgs e)
{
    if (loginOK)
   {
            Control[] cm = Parent.Controls.Find("UserControl1", true);
            cm[0].Visible = true;
            this.Visible = false;
    }
}

Dentro lo Usercontrol1:

private void button1_Click(object sender, EventArgs e)
 {
           
            if (radioButton1.Checked == true)
            {
                Control[] ns = Parent.Controls.Find("UserControl2", true);
                ns[0].Visible = true;      
            }
            else
            {
                Control[] es =Parent.Controls.Find("UserControl3", true);
                es[0].Visible = true;
            }


             this.Visible = false;
}

Dentro lo userControl2

private void button13_Click(object sender, EventArgs e)
{
            


            Control[] cm = Parent.Controls.Find("UserControl1", true);
            cm[0].Visible = true;


            this.Visible = false;
        


}

Dentro lo UserControl3

private void button13_Click(object sender, EventArgs e)
{
            


            Control[] cm = Parent.Controls.Find("UserControl1", true);
            cm[0].Visible = true;


             this.Visible = false;
        
}
