Question

I have five buttons on one form that when clicked enables a bool each to be true or false, they also load a new form. When that form is loaded I need the new form to check first which of those bools are true or false. This will then lead to the form loading the correct data.

I set the bools to public thinking that this would work, and in the form2_load i checked which one is true. however this does not seem to work. I tried first by just changing a label and it’s text. The text doesn’t changed and I don’t think the bools are being read or checked.

Does anyone know what the problem could be?

Form1 code:

public bool Room1;
public bool Room2;
public bool Room3;
public bool Room4;
public bool Room5;

private void btnRoom1_Click(object sender, EventArgs e)
    {
        this.Hide();

        //This displays Form2
        Form2 RoomTemplate = new Form2();
        RoomTemplate.Show();

        Room1 = true;
        Room2 = false;
        Room3 = false;
        Room4 = false;
        Room5 = false;

    }

Form2 code:

public Form3()
    {
        InitializeComponent();
        Form2 Rooms = new Form2();

        if (Rooms.Room1 == true)
        {
            lblTitle.Text = "Living Room";
        }

        if (Rooms.Room2 == true)
        {
            lblTitle.Text = "Dining Room";
        }

This is one way to do it:

public bool Room1;
public bool Room2;
public bool Room3;
public bool Room4;
public bool Room5;
private void btnRoom1_Click(object sender, EventArgs e)
{
    this.Hide();

    Room1 = true;
    Room2 = false;
    Room3 = false;
    Room4 = false;
    Room5 = false;

    //This displays Form2
    Form2 RoomTemplate = new Form2(this);
    RoomTemplate.Show();
}

public class Form2()
{
    public Form2(Form1 form1)
    {
        InitializeComponent();
        if(form1.Room1 == true)
        {
            lblTitle.Text="Living Room";
        }
        else if(form1.Room2==true)
        {
            //
        }
        //
    }
}
