Using Delegate with CheckBox[] to pass between Forms

Is it possible to use CheckBox[] within a Delegate to pass the data to and from a second form?

 Please go easy on me as I am way to old to be a student and am self taught (kinda).  I just have some spefic needs that I am working on.

 

This is what I have done:

 Without the CheckBox[] it works fine sending strings back and forth between forms.  When I add the CheckBox[] it goes on vacation!

 

Main Form

public delegate void EditItemDelegate(string txt1, string txt2, string txt3, CheckBox[] checkBoxes);
 

Click Event to Open Second Form ()

{

                  //  Pass Data to Second Form

                 frm_MyGlobalDrawObjects frm = new frm_MyGlobalDrawObjects();
                
                frm.textBox1.Text = "Test 1";
                frm.textBox2.Text = "Test 2";
                frm.textBox3.Text = "Test 3";
                
                //  CheckBox[] is created elsewhere

               //   The number of CheckBoxes created will be dynamic depending on other conditions

               //   This works to create the CheckBoxes on the Second Form

               //    and adds the CheckBoxes to a GroupBox
                foreach(KeyValuePair kvp in ChartsForGlobal)
                {
                        foreach (CheckBox ck in kvp.Value)
                        {
                            CheckBox cb = new CheckBox();
                            cb.Name = ck.Name;
                            cb.Location = ck.Location;
                            cb.Text = ck.Text;
                            cb.Checked = ck.Checked;
                            frm.gbx_GlobalChartSelection.Controls.Add(cb);
                        }
                }                
               
                frm.EditItemCallback = new EditItemDelegate(this.EditItemCallbackFn);
                
                frm.Show();

 

             private void EditItemCallbackFn(string txt1, string txt2, string txt3, CheckBox[] checkBoxes)
            {
                Print(String.Format(" Updated TextBox 1 {0}", txt1 ));
                Print(String.Format(" Updated TextBox 2 {0}", txt2 ));
                Print(String.Format(" Updated TextBox 3 {0}", txt3 ));

 

                //  Clueless begins here.  Not able to get CheckBox[] from Second Form.
                //  Need to Loop through the CheckBox[]

                //   If Checked. do something

               //  else do something different

            }           

 

Second Form

         public EditItemDelegate EditItemCallback;

 

         public frm_MyGlobalDrawObjects()
        {
            InitializeComponent();
        }
        private void frm_btn_Save_Click(object sender, EventArgs e)
        {

            //   Does NOT like the way I have CheckBox[] here.
            EditItemCallback(textBox1.Text, textBox2.Text, textBox3.Text, CheckBox[] checkBoxes  );
            this.Close();
        }

 

Many, many thanks for anyone that can offer some suggestions.
