Your code looks like OK to me. It should fire the DeleteCommand.

But the problem is that I am sure you are binding the Datalist in your page_load event, but not under If(!IsPostBack) condition. What happens when you hit Delete button is your page_load event fires before your DeleteCommand and it rebinds the DataList and your event is lost

Your page_load event code should look like...

If(!IsPostBack) 
{
  DataList binding code goes here......
  ...........................
}

protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    // Bind the DataList here....
}
