Question

I have an asp.net webpage that contain a gridview with edit, select and delete enabled, and a detailview for inserting new record. Each control is placed inside a asp.net ajax extension control-updatepanel. And the two controls are bonded to the same datasource which is LinqDataSource.

After new record was inserted nothing display in the gridview until user refresh the page.
Did I miss something? Can anyone help?

<asp:ScriptManager ID="ScriptManager1" runat="server" />
<fieldset>

<asp:UpdatePanel ID="UpdatePanel2" runat="server">       
    <ContentTemplate>
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
        DataSourceID="TermLinqDataSource" AllowPaging="True" AllowSorting="True" 
        DataKeyNames="TermID">
        <Columns>
            <asp:CommandField 
                ShowSelectButton="True" />
            <asp:BoundField DataField="RowIndex" HeaderText="RowIndex" 
                InsertVisible="False" SortExpression="RowIndex" Visible="False" />
            <asp:BoundField DataField="TermID" HeaderText="Term" ReadOnly="True" 
                SortExpression="TermID" />
            <asp:BoundField DataField="StartDate" HeaderText="Start Date" 
                SortExpression="StartDate" DataFormatString="{0:d}" />
            <asp:BoundField DataField="EndDate" HeaderText="End Date" 
                SortExpression="EndDate" DataFormatString="{0:d}" />               
            <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />  
        </Columns>                        
    </asp:GridView>
    </ContentTemplate>
    </asp:UpdatePanel>

I think you need to bind gridview again after insertion.
