Gridview outside UpdatePanel not showing

Question

I have an ItemCommand event in a button found in a listview.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
    <asp:ListView ID="systemsView" runat="server" 
        onitemcommand="systemsView_ItemCommand">
        <ItemTemplate>
            <asp:Button ID="btnView" runat="server" Text='<%#Eval("SYSTEM_DESC") %>' CommandArgument='<%# Eval("ROW_ID")%>'
                class="systemButtonStyle" />
        </ItemTemplate>
    </asp:ListView>
</ContentTemplate>                        
</asp:UpdatePanel>

When the itemCommand is fired I want to bind another gridview which is not inside the update panel. The gridview is not showing when the event is fired. Any ideas how I could solve this problem please?

grid view should also be in update panel – Ehsan Sajjad Apr 10 '14 at 14:26 — Ehsan Sajjad, Apr 10 '14 at 14:26

Since UpdatePanels only perform a PostBack on controls within their ContentTemplate, all controls that are expected to be updated by a Partial PostBack must be housed within the same UpdatePanel's ContentTemplate.

If you need to update something outside of an UpdatePanel with an action that occurs within it's Partial PostBack, you will have to rethink your use of the UpdatePanel.

Two solutions:

Add the other GridView to the UpdatePanel's ContentTemplate.
Remove the UpdatePanel entirely and use the normal PostBack.

I've added another update panel and worked as I wanted. Thanks – chrisdeb Apr 10 '14 at 14:42
An alternative is to call a bit of javascript to click a button to populate the gridview outside the update panel. I do this all the time as I find pages with multiple update panels, sooner or later, do something weird. – Martin Smellworse Apr 10 '14 at 15:10
Yeah, with modern jQuery, the UpdatePanel has been somewhat deprecated. – Garrison Neely Apr 10 '14 at 15:11
