Hi setwell,
You can only trigger the parent controlId. In your condition you are triggering parent and child controlId therefore your updatePanel is not firing.
Please refer below sample.
HTML
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="FruitName" HeaderText="Fruit Name" />
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkPartial" runat="server" Text="Partial PostBack" OnClick="PartialPostBack" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkFull" runat="server" Text="Full PostBack" OnClick="FullPostBack" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:LinkButton ID="lnkFruit" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" />
<asp:AsyncPostBackTrigger ControlID="lnkFruit" />
</Triggers>
</asp:UpdatePanel>
