Sort Child Items in Parent Widget Template
I have the following code listing Child Items within a Parent Widget Template.
<sf:DynamicDetailContainer ID="detailContainer" runat="server"> <LayoutTemplate> <asp:Repeater runat="server" DataSource='<%# Eval("ChildItems") %>'> </asp:Repeater> </LayoutTemplate></sf:DynamicDetailContainer>I would now like to order the Child Items by a custom property, i.e. SortOrder, with something like the following which calls a helper function (see below)
<sf:DynamicDetailContainer ID="detailContainer" runat="server"> <LayoutTemplate> <asp:Repeater runat="server" DataSource='<%# Helpers.SortOrder(Eval("ChildItems")) %>'> </asp:Repeater> </LayoutTemplate></sf:DynamicDetailContainer>Using the helper function below, I keep getting the following error " Database mapped field uses different type 'System.Nullable' "
public static IQueryable<DynamicContent> SortOrder(object dynamicContent) var collection = (IQueryable<DynamicContent>) dynamicContent; return collection .OrderBy(x => x.GetValue<int?>("SortOrder"));
Am I going along the right lines?
Hello Sean,
In order to get the value of your custom field of type Number, please use decimal instead of int.
public static IQueryable<DynamicContent> SortOrder(object dynamicContent) var collection = (IQueryable<DynamicContent>) dynamicContent; return collection .OrderBy(x => x.GetValue<decimal?>("SortOrder"));
