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.DragEventArgs e)
private void DatasetControl_DragEnter(object sender,
System.Windows.Forms.DragEventArgs 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.DragEventArgs e)
private void Form1_DragDrop(object sender,
System.Windows.Forms.DragEventArgs 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.DragDrop(sender,e); seems to complain, any tips?
Also this.ParentForm.Form1_DragDrop(sender,e) does not work
