Question

I have a GridView that is bound to a SQL Data source. I have put this inside an Update panel and want the contents to update at a specified interval. The problem is that if i change the data in the database, the GridView does not update itself, i have to manually refresh the page to view the new data.

What else do I need to do to get a GridView to refresh itself?

<asp:Timer ID="RefreshTimer" runat="server" Interval="10000" 
    ontick="RefreshTimer_Tick">
</asp:Timer>

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>

        <div id="quad1"><uc1:MyWidget ID="MyWidget1" runat="server" /></div>

    </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="RefreshTimer" EventName="Tick" />
    </Triggers>
</asp:UpdatePanel>

You have to call gridView.DataBind() on tick event
