How Make a button dynamically?

I'm doing a "list" of buttons, like a Menu in a Form, and I'm trying to do it out of a table in a database, I'm doing this like this: 

foreach (Catalogos catalogo in catalogos)
{
    SimpleButton sb = new SimpleButton();
    sb.Text = catalogo.Nombre;
    sb.Click += catalogo.Evento;
    LayoutControlItem item = new LayoutControlItem();
    item.TextVisible = false;
    item.Control = sb;
    lcg.Add(item);
 }

My problem is in the sb.Click += catalogo.Evento line, how can I do the eventy dynamically

option 1

Create a SimpleButton_Click method in your form

private void SimpleButton_Click(object sender, EventArgs e)
{
    //using (SimpleButton)sender you can find which botton is clicked
}

then in your loop, assign that method to Click event:

sb.Click += new System.EventHandler(this.SimpleButton_Click);

option 2

assign a delegate/lambda expression to event this way:

//instead of sender and e, usually you should use different names
//because usually you are running this code in an event handler
//that has sender and e parameters itself
sb.Click += (object senderObject, EventArgs eventArgs) => 
{
   //using (SimpleButton)sender you can find which botton is clicked
};

Use a lambda / anonymous method

SimpleButton sb = new SimpleButton();
sb.Text = catalogo.Nombre;
sb.Click += (sender, evntArgs) => {
    //some dynamic mouse click handler here.
};
