RowDetailsTemplate doesn't autosize back - Silverlight DataGrid

Question

Hi,

Please look at the attached screenshots.

I'm adding a datagrid to the rowdetails area for each row in the template.

The problem I have now is that the rowdetails area sizes correctly when it gets larger, ie when more content is added.

But once you collapse those rows(and their corresponding rowdetails) and open another rowdetail that is smaller than the first one, the rowdetails container does not resize back(ie smaller) to fit the smaller content.

Please refer to the following flickr set, as I am not allowed to post images or more than one hyperlink: http://www.flickr.com/photos/47755109@N08/sets/72157623590404492/

How do I fix this issue?
