Display web parts using <asp:GridView ID="WebPartsGridView" runat="server" a GridView control AutoGenerateColumns="False" DataSourceID="WebPartsDataSource" DataKeyNames="ID"> <Columns> <asp:CommandField ButtonType="Button" ShowDeleteButton="True" /> <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" /> <asp:TemplateField HeaderText="Zone"> <ItemTemplate> <asp:Label ID="Label1" Text='<%# Eval("Zone.DisplayTitle") %>' runat="server" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="ZoneIndex" HeaderText="ZoneIndex" SortExpression="ZoneIndex" /> </Columns> </asp:GridView>
