Protected Sub GridView_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView.RowDataBound

If (e.Row.RowType <> ListItemType.Header And e.Row.RowType <> ListItemType.Pager) Then
If ContienePalabra(e.Row.Cells("Producto").Text, "PalabraBuscar") Then
e.Row.BackColor = Color.Yellow
End If
End If
End Sub

Public Function ContienePalabra(ByVal Palabra As String, ByVal Texto As String) As Boolean
If Texto.Contains(Palabra) Then
Return True
Else
Return False
End If
End Function

Reemplaza "PalabraBuscar" por el valor de la palabra verdadera a buscar ok.
Suerte.
