I am Creating Form like    Form 1= Main Form   Form 2= Setting Form Form 3= Lock Form   write in Setting form code:       public partial class Form2 : Form {   Form1 f1; Form3 f3;    public Form2() { InitializeComponent(); if (checkBox1.Checked) { if (f3 != null) f3.Dispose(); f1 = new Form1(); f1.Show(); } else { if (f1 != null) f1.Dispose(); f3 = new Form3(); f3.Show(); } }   private void checkBox1_CheckedChanged(object sender, EventArgs e) { if(checkBox1.Checked) { if (f3 != null) f3.Dispose(); f1 = new Form1(); f1.Show(); } else { if(f1!=null) f1.Dispose(); f3 = new Form3(); f3.Show(); } } }       write form 3 Code:   private void Cancel_Click(object sender, EventArgs e) { Form1 f1 = new Form1(); f1.Show(); this.Dispose(); }       I think its use for you.    But you con't change the checkbox selection when lockform cancel   (This time checkbox selected is using only using "Delegate")   Delegate methods are using method invoking so its possible to update working one form you can update another form    Try it all the best

You can do by using checkbox event change or checked event & write your logic in that on change event, if checkbox is checked then show mainform else show lockform.
