Expanding a Datagrid

If am using an XML document to load a datagrid..

ds.ReadXMl(sb.ToString())
dgXml.DataSource=ds
dgXml.TableStyles.Add ( XmlStyle )
dgXml.Expand(0)

When the grid is loaded it is not "fully open" (see attached image) and I have to click the "item" to fully expand to the final dataset. What am I missing??

Thanks....

If you want to select a specific table in the dataset use that table as the dataset.

VB Code:

ds.ReadXMl(sb.ToString)
dgXml.DataSource=ds[b].Tables(0)[/b]
dgXml.TableStyles.Add ( XmlStyle )
dgXml.Expand(0)

The best .. thanks......
