Dynamically add click event to other forms

Question

I want to dynamically add a click event from form1 to form2.

This is my code in form1:

Form2 frm = new Form2();
string title =(string)listBox1.SelectedItem;
TabPage myTabPage = new TabPage(title);
frm.tabControl1.TabPages.Add(myTabPage);
//create button and it's event
Button button1 = new Button();
button1.Click += new System.EventHandler(button1_Click);
button1.Location = new Point((myTabPage.Width/2)-(button1.Width/2),myTabPage.Height-30);
button1.Text = "Click On Me!";
myTabPage.Controls.Add(button1);
frm.Show();

I get the following error: The name 'button1_Click' does not exist in the current context

Please help.

Have yo defined button1_Click any where on new form? If no, you must define it before binding it to any button click event. — donstack

You need to create your button1_Click event handler. At the moment you're assigning the event handler to the button saying "call button1_Click" but you haven't actually created the "button1_Click" method that you want to call.

private void button1_Click(object sender, EventArgs e) 
{
   //code to call when the button is clicked.  
}

Update from comment. You can create an anonymous method.

button1.Click += (s,e) =>
     { 
         //code to call when the button is clicked. 
     };

Could you create the button ahead of time and disable and make invisible until you wanted to use it?
