How to pass a function to a Class on the presentation page.

Question

User1456393972 posted

I have a class that inherits from CompositeControl.  Inside my class, I have a button.  I want to declare the click event of the button from the presentation page. e.i.

//Default.aspx:

<custom:FormShell ID="Shell1" OnOk="MyFunction" >
     <custom:FormShellContent runat="server">                       
          <p>Some Content</p>                             
     </custom:FormShellContent>
</custom:FormShell>

Here is an example (that does not work) of what I am trying to accomplish in code (see last setter).

//FormShell.cs:

using System;
using System.Collections;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace myControls
{
    public class FormShellContent : Control { }

    [ParseChildren(true, "Items")]
    public partial class FormShell : CompositeControl
    {
        //Button
        protected Button myButton = new Button();        

        protected override void CreateChildControls()
        {             
            //Add the button
            this.Controls.Add(myButton);

            //Add the content of the Formshell
            m_cell[1, 1].Controls.Add((Control)m_items[0]);
        }

        [Browsable(false)]
        public ArrayList Items
        {
            get { return m_items; }
        }

        //This does not work, How can I do something similar to
        //this so that i can declare the function from the presentation page?
        public event OkClick
        {   
            set{ myButton.Click += new EventHandler(value); }
        }
    }
}
