Your setting the Visible property[^] of the form which is not the same as calling the Close method[^]. If you really want the form to be closed instead of just being invisible do use the Close method.

Thanks Manfred
I have used closed method but as i clicked button to jump on next form my whole application is getting close. :(

yes because you Close the main Form you should use Hide()
Manfred Rudolf Bihy 22-May-12 9:39am    
So how come you always talk about closing the form when all you want to do is to hide it? You seem a little confused to me. :)
Closing the main form will of course close the application.

My 5, taking into account this note. Most likely, capturing FormClosing to cancel closing of the form and calling Hide instead should work for OP.

Hi ,
Check this Example

C#
public partial class Form1 : Form
 {
     public Form1()
     {
         InitializeComponent();
     }
     private void Form1_Load(object sender, EventArgs e)
     {
     }

     private void button1_Click(object sender, EventArgs e)
     {
         Form2 frm = new Form2();
         frm.Show();
         this.Hide();
     }
 }


C#
public partial class Form2 : Form
   {
       Form1 frm = new Form1();
       public Form2(Form1 frm2)
       {
           InitializeComponent();
           frm = frm2;
       }
          public Form2()
       {
           InitializeComponent();
       }
       private void Form2_Load(object sender, EventArgs e)
       {

       }
       private void button1_Click(object sender, EventArgs e)
       {
           frm.Show();
           this.Close();

       }
   }

Best Regards

Thanks to all its working fine now.
:)

Your welcome :)
Manfred Rudolf Bihy 22-May-12 9:41am    
Hmm, I think OP is a little confused. Ofcourse closing a main form closes the application, but why does OP keep talking of closing the form when his true intentions are to hide it.
Mohamed Mitwalli 24-May-12 9:37am    
Yes Agree with you .
Prasad_Kulkarni 23-May-12 3:39am    
This is 5 worthy!
this.Hide();
var otherform = new Form2();
otherform.Closed += (s, args) => this.Close();
otherform.Show();

I know its late but hope it helps! :)

Try NINE years late, and you didn't add anything to the discussion that happened way back then.

Hi Dave,

Just a reminder it is OK to answer old questions. You are, of course, very welcome to downvote or report solutions that you feel don't anything to the discussion.
Hello all, below code will work perfectly fine, use 'hide()' method to hide the current form and open another form using 'Show()' method on the new forms instance,
public partial class Login : Form
    {
        public Login()
        {
            InitializeComponent();
        }

        private void Login_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            if(txtUnm.Text == "Optiq" && txtPwd.Text == "vision_13")
            {
                this.Hide();
                var formConfig = new FormConfiguration();
                formConfig.Show();
            }
            else
            {
                MessageBox.Show("Invalid username and password");
            }
        }
    }

Reason for my downvote: You have added nothing new to this thread and have included irrelevant code which just confuses the solution
