Without seeing any code here is my 2 cents and a shot in the dark at what you are asking.
Lets call the place in your control where you do databinding "MyDataBindingMethod". Then all we need to do is define the event and handler and if you wish custom event args I will not use custom args here, and simply use the provided System.EventArgs

public event EventHandler MyCustomDataBoundEvent;
public void MyCustomDataBoundEvent(object sender, EventArgs e)
{
      if (MyCustomDataBoundEvent!= null)
      {
             MyCustomDataBoundEvent(this, e);
      }
}

protected void MyDataBindingMethod(){
//this method is already defined in your control somewhere
// we can use it to call MyCustomDataBoundEvent
some code to bind data to your control
//then next lets call our custom event
MyCustomDataBoundEvent(this,System.EventArgs.Empty);
}

Thats it, very simple! You can also use attributes to define a default event for your control. The advantage of this is that when you double click the control VS automatically adds the code to the code behind and wires up the event for you, pretty slick.

here is and example...

[DefaultEventAttribute("MyCustomDataBoundEvent")]
public class MyCustomControl : WebControl
{....}

notice this has to be defined at the class level not the event definition.

Hope this helps!
