passing on Control DragDrop to parent DragDrop

I create an user control (combined form with many controls) where I process
the

private void DatasetControl_ DragDrop(object sender,
System.Windows. Forms.DragEvent Args e)
private void DatasetControl_ DragEnter(objec t sender,
System.Windows. Forms.DragEvent Args e)

Now I drop this Dataset Conttrol on my main form, and I also want to process

private void Form1_DragEnter (object sender,
System.Windows. Forms.DragEvent Args e)
private void Form1_DragDrop( object sender,
System.Windows. Forms.DragEvent Args e)

The intention is that the DatasetControl_ DragDrop processes its drops that
it knows of but should all the parent (Form1_DragDrop ) for all drops that he
does not know of.

The big question is how to pass on the DatasetControl_ DragDrop() to the
Parent Form1_DragDrop( )????

ParentForm.Drag Drop(sender,e); seems to complain, any tips?
Also this.ParentForm .Form1_DragDrop (sender,e) does not work
