and null fields

[Tina]

in the itemDatabound event of a datagrid, both null fields and blank string
come through as   in the e.items.cells field. Is there anyway to tell
them apart?
Thanks,
T

Not really. The "&" character sequence is used in HTML table cells to
ensure that all browsers will display the cell that is empty. Some browsers
will not draw the cell if it has nothing in it.

Yes there is a way to tell...

If e.Item.ItemType <> ListItemType.Footer AndAlso _
e.Item.ItemType <> ListItemType.Header AndAlso _
e.Item.ItemType <> ListItemType.Separator AndAlso _
e.Item.ItemType <> ListItemType.Pager

' If the data item is a data set, use the following :
Dim ds As DataSet = DirectCast(e.Item.DataItem, DataSet)

' If it's a data table, use the following :
Dim dt As DataTable = DirectCast(e.Item.DataItem.Row, DataRow)
End If

FYI, I received an execellent solution over in the datagrid forum...

simply look in the source dataset to tell the difference! It's always easy
once you know how.
