Consider implementing DataGridView.Row(x).HeaderCell.Value to comply with WinForms
Looping through rows of DataGridView and setting DataGridView.Row(x).HeaderCell.Value / tool tip/ tag to some text.
Setting the Value has no effect, neither in DHTML nor Silverlight.
Check the DataGridView.Row(x).HeaderCell.Style also, as it could not be tested, as no value was shown.
Tested on VWG 6.2.3 NET3.5 in IE7 and FF3, both DHTML and SilverLight
Sample application(s) attached, one for VWG, other in WinForms.
Application(s) self explanatory. Just click the button to have the rowheaders added.
