Hi Guys

I have a problem.I have a GridView with a LinkButton.
I need to click in this Linkbutton to open a Modal Pop Up but I need to send the ID field together to recover it in the next page (modal pop up).

How can I do it, please?

I am trying this way but there is a wrong in anyplace.

<asp:LinkButton ID="LinkButton3" runat="server" CommandName= "PegaID" CommandArgument='<%#Eval("REL_ID")%>' OnClientClick="openModal('Documentos.aspx?rel_id='+<%#Eval("REL_ID")%>, 800, 600);'"><%#Eval("REL_DOCUMENTO")%></asp:LinkButton>

Can you help me please.

Thanks a lot
