Here is how I got it to work -with help - so if anyone else needs a snip of working color the cell based on data here you go. And thank you for all of the help.
<script runat="server">
Sub Datagrid1_ItemDataBound(source As Object, e As DataGridItemEventArgs)
If (e.Item.ItemType = ListItemType.Item Or _
e.Item.ItemType = ListItemType.AlternatingItem) Then
If e.Item.DataItem("Curr_Qtr") = "Stop" Then _
e.Item.Cells(2).BackColor = System.Drawing.Color.DeepPink
End If
End Sub
</script>
