body: <p>Everything was running smoothly until I tried to test out my asp page in chrome for the 1000th time and this time it gave me this error and I cant seem to find whats wrong</p>
  
  <pre><code>Compiler Error Message: CS1061: 'default_aspx' does not contain a definition for 'GridView2_SelectedIndexChanged1' and no extension method 'GridView2_SelectedIndexChanged1' accepting a first argument of type 'default_aspx' could be found (are you missing a using directive or an assembly reference?) 
  
  &lt;asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"      DataKeyNames="ISBN" DataSourceID="SqlDataSource2" EmptyDataText="There are no data records to display." OnSelectedIndexChanged="GridView2_SelectedIndexChanged1"&gt;
