In the GridView RowDataBound event I am checking for the Row.RowState value.
As far as I know those are the available DataControlRowStates:

Normal = 0,
Alternate = 1,
Selected = 2,
Edit = 4,
Insert = 8

When I step into the code I noticed that in some cases my Row.RowState = 7.

Does anyone knows what 7 is ?
Thank you,
Daniel
