Hi,
How can I default the highlighted value so that it is not checked?
Thanks!

Sorry the image did not save I had to attached. See attached.
The header checkbox defaults to unchecked. So I don't know why yours is checked. How are you turning on the header checkboxes? Are you setting the HeaderCheckBoxSynchronization?
To explicitly set the value of the checkbox, you call the SetHeaderCheckedState method on the column. And you have to pass in the rows collection. In your case, since your screen shot shows child rows, you would have to call it for the child rows of every parent row.
