In the event that you need to setup click events for your dynamically created buttons, I would suggest you use button Commands and CommandArgs to indicate what to do and what to do it to.

In this example, I placed a PlaceHolder control into the form where I will want to dynamically place buttons.

// add a dynamic button with command args
        Button mybtn = new Button();
        mybtn.ID = "btnDynamicButton";
        mybtn.Text = "Edit";
        mybtn.CommandName = "Edit";
        mybtn.CommandArgument = "Comments";
        mybtn.Command += new CommandEventHandler(mybtn_Click);
        PlaceHolder1.Controls.Add(mybtn);

Now here is the event handler (will handle all dynamic buttons created with the above code as indicated by the mybtn.Command += ...)

protected void mybtn_Click(object sender, EventArgs e)
    {
        // figure out which action is being requested
        if (((Button)sender).CommandName == "Edit")
        {
            // we are editing
            // figure out what area is being worked on
            string AreaToEdit = ((Button)sender).CommandArgument;
            
            // now we know that we are editing the comments content       
            // put here whatever you want to do to open an editor

            
            // just for testing
            Response.Write("Mode: " + ((Button)sender).CommandName + " - Action: " + AreaToEdit);
        }
    }
