datagrid parent--> child relation

I am working in vb.net with a datagrid. I have setup the parent child relationship of two tables, using the datarelation object and adding that relation to the dataset.

However, my question is when I run the application and click on the little plus sign to bring up the child data in the datagrid, it come up with a link that I must click on in order to see the child data.

Is there a way to remove that child relation link and just open the child data when I click on the plus sign.

Any help would be great thanks.
