How do I recognize dynamic buttons as triggers for updating updatepanels?

I have two updatepanels on a page each with a datagrid inside the panels. I need updatepanel B to update it's datagrid when a LinkButton is clicked inside udatepanel A's datagrid. The linkbuttons are dynamically generated for each row of the datagrid.

Thanks

Stripped Down Example:

<asp:UpdatePanel id="pnl1" runat="server">
<ContentTemplate>
<asp:datagrid id="dgA" runat="server" > ... <asp:LinkButton ID="lbtnSelect" CommandArgument=' ... ' runat="server">...</asp:LinkButton> ... </asp:datagrid>
</ContentTemplate>
</asp:UpdatePanel>

<!-- Next Panel -->

<asp:UpdatePanel id="pnl2" runat="server">
<ContentTemplate>
<asp:datagrid id="dgB" runat="server" > ... </asp:datagrid>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lbtnSelect" EventName=" ... "/>
</Triggers>
</asp:UpdatePanel>

Unless I misread your post, I think that all you need to do is add the following line inside of your event handler for the link buttons (lbtnSelect_Click, or similar):

pnl2.update();

This should update your pnl1 because the linkbutton's click event fired inside of pnl1, andprogrammatically updating pnl2 with pnl2.update() should take care of updating the other datagrid (dgB). You can get rid of the <Triggers> definition too.
