Need to get ascx behavior into a aspx file, with Dynamic Data

I like the way the Custom Control allows me to rename columns in the Label_Init Event. But I find no such ability with the Details.aspx page.

I am a bit lost in this script code that's auto generated for an out-of-the-box Dynamic Data website.

Please point out how I can get the Details.aspx Page to call an event when ASP.NET is rendering the page, since I need to assign different values for the lable.Text for each column.

Thanks,

Custom Control
==============
<%@ Control Language="C#" CodeBehind="Default_Insert.ascx.cs" Inherits="RDDBWebAdmin.Default_InsertEntityTemplate" %>

<%@ Reference Control="~/DynamicData/EntityTemplates/Default.ascx" %>

<asp:EntityTemplate runat="server" ID="EntityTemplate1">
    <ItemTemplate>
        <tr class="td">
            <td class="DDLightHeader">
                <asp:Label runat="server" OnInit="Label_Init" OnPreRender="Label_PreRender" />
            </td>
            <td>
                <asp:DynamicControl runat="server" ID="DynamicControl" Mode="Insert" OnInit="DynamicControl_Init" />
            </td>
        </tr>
    </ItemTemplate>
</asp:EntityTemplate>


Details.aspx Page
=================
<%@ Page Language="C#" MasterPageFile="~/Site.master" CodeBehind="Details.aspx.cs" Inherits="RDDBWebAdmin.Details" %>


<asp:Content ID="headContent" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:DynamicDataManager ID="DynamicDataManager1" runat="server" AutoLoadForeignKeys="true">
        <DataControls>
            <asp:DataControlReference ControlID="FormView1" />
        </DataControls>
    </asp:DynamicDataManager>

    <h2 class="DDSubHeader">Entry from table <%= /*table.DisplayName*/ Title %></h2>

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:ValidationSummary ID="ValidationSummary1" runat="server" EnableClientScript="true"
                HeaderText="List of validation errors" CssClass="DDValidator" />
            <asp:DynamicValidator runat="server" ID="DetailsViewValidator" ControlToValidate="FormView1" Display="None" CssClass="DDValidator" />

            <asp:FormView runat="server" ID="FormView1" DataSourceID="DetailsDataSource" OnItemDeleted="FormView1_ItemDeleted" RenderOuterTable="false">
                <ItemTemplate>
                    <table id="detailsTable" class="DDDetailsTable" cellpadding="6">
                        <asp:DynamicEntity runat="server" />
                        <tr class="td">
                            <td colspan="2">
                                <asp:DynamicHyperLink runat="server" Action="Edit" Text="Edit" />
                                <asp:LinkButton runat="server" CommandName="Delete" Text="Delete"
                                    OnClientClick='return confirm("Are you sure you want to delete this item?");' />
                            </td>
                        </tr>
                    </table>
                </ItemTemplate>
                <EmptyDataTemplate>
                    <div class="DDNoItem">No such item.</div>
                </EmptyDataTemplate>
            </asp:FormView>

            <asp:EntityDataSource ID="DetailsDataSource" runat="server" EnableDelete="true" />

            <asp:QueryExtender TargetControlID="DetailsDataSource" ID="DetailsQueryExtender" runat="server">
                <asp:DynamicRouteExpression />
            </asp:QueryExtender>

            <br />

            <div class="DDBottomHyperLink">
                <asp:DynamicHyperLink ID="ListHyperLink" runat="server" Action="List">Show all items</asp:DynamicHyperLink>
            </div>
        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Content>

I'm not entirely sure what the question is.  I will work off of your statement:
"Please point out how I can get the Details.aspx Page to call an event when ASP.NET is rendering the page"

The event that is called prior to a page being rendered would be the Page PreRender event.  It looks like you do not have autoeventwireup set to true on your page, so you would have to override the prerender event using the following code in the codebehind file for your page:

protected override void OnPreRender(EventArgs e) {
  base.OnPreRender(e);
  //Do your PreRender logic here
}

That does indeed hit the breakpoint when rendering the page.

How do I determine of the "sender" is a column header label?

Thanks,

In fact, I just noticed it gets called once for the page, not once for each label.

I'm a little confused at how to use this event?
