Sorting in a Nested Repeater

[sitefinitysteve]

I bound a nested repeater to a collection inside my dataset (by just using an Eval on the DataSource property in the markup)

Now I have an index column to sort these results by, but how can I get that sorting to take effect in this "codeless" context.  I mean I could handle ItemDataBound and get\sort the collection myself, but I was hoping to avoid that :)

I tried returning a sorted list from inside the OA Property itself, but that didnt seem to work

        [Telerik.OpenAccess.FieldAlias("publicationsItem")]
        public IList<PublicationsItem> PublicationsItems {
            get {
                return (from p in publicationsItem
                        orderby sortIndex
                        select p).ToList();
            }
        }

Is this even doable?

Hello Steve,

You should handle the column header click event in order to sort the repeater data:

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        <table width="100%" cellspacing="0" cellpadding="0">
            <tr>
                <td width="25%">
                    <%# DataBinder.Eval(Container.DataItem, "EmployeeID") %>
                </td>
                <td width="25%">
                    <%# DataBinder.Eval(Container.DataItem, "FirstName") %>
                </td>
                <td width="25%">
                    <%# DataBinder.Eval(Container.DataItem, "LastName") %>
                </td>
                <td width="25%">
                    <%# DataBinder.Eval(Container.DataItem, "Title") %>
                </td>
            </tr>
        </table>
    </ItemTemplate>
    <HeaderTemplate>
        <table width="100%" cellspacing="0" cellpadding="0">
            <tr>
                <td width="25%">
                    <asp:LinkButton ID="lnkEmployeeid" runat="server" OnClick="SortByEmployeeId">EmployeeId</asp:LinkButton>
                </td>
                <td width="25%">
                    <asp:LinkButton ID="lnkFirstName" runat="server">FirstName</asp:LinkButton>
                </td>
                <td width="25%">
                    <asp:LinkButton ID="lnkLastName" runat="server">LastName</asp:LinkButton>
                </td>
                <td width="25%">
                    <asp:LinkButton ID="lnkTitle" runat="server">Title</asp:LinkButton>
                </td>
            </tr>
        </table>
    </HeaderTemplate>
</asp:Repeater>

protected void SortByEmployeeId(object sender, EventArgs e)
{
    Repeater1.DataSource = context.Employees.OrderBy(emp => emp.EmployeeID);
    Repeater1.DataBind();
}

There is no codeless approach to achieve this goal.
