Hi Allon,
Thank you for your interest in Syncfusion products.
There is no built-in support for sorting rows. But it can be achieved by Custom IComparer's.
Refer the sample from below link to sort a rows:
http://files.syncfusion.com/support/samples/Grid.Windows/Forums/SortRows.zipAlso the GridControl does not have default property to sort the columns with column header. However It can be achieved with Data.SortByColumn method in GridControl. In that method the IComparer object is used to sort the data's in GridControl.
Refer the sample in below link, it demonstrate the Sorting in GridControl.
