Get expanded parent row from CommandItemTemplate in DetailsTable

[davortsan]

Hi mates,

I have a Telerik RadGrid with a DetailsTable, and the following CommandItemTemplate is in this DetailsTable:
<CommandItemTemplate>
< asp:LinkButton ID="btnNuevoAperitivoFrioIng" runat="server" ForeColor="#384e73" OnClick="btnNuevoAperitivoFrioIng_Click" ><img style="border:0px;vertical-align:middle; height:24px; width:24px" alt="" src="../img/buttons/add.png"/>Nuevo</asp:LinkButton>
< /CommandItemTemplate> 
I need to get the ID of the expanded parent row when I clic on btnNuevoAperitivoFrioIng (in the btnNuevoAperitivoFrioIng_Click function). How could I get this ID, please?

Thanks a lot in advance.

Cheers.
