    Hello all,

    I've designed a custom bread crumb control for several of my
    projects. The default property of this control is a custom
    HyperLinkCollection I've created, which contains, you guessed it, HyperLink
    objects. All of it works great if I create/assign the links at runtime in
    code. I'd like to be able to assign links at design time, which is possible
    using the properties window, but currently, they do not carry over to the
    runtime. I'm trying to figure out how to make this happen. Sample code for
    the small breadcrumb class is listed below. I would greatly appreciate any

    using System;

    using System.Collections;

    using System.Web.UI;

    using System.Web.UI.WebControls;

    using System.ComponentModel;

    namespace Com.L3Software.Web.Controls {

    /// <summary>

    /// Summary description for Breadcrumb.

    /// </summary>



    ToolboxData("<{0}:Breadcrumb runat=server></{0}:Breadcrumb>"),

    Description("A reusable breadcrumb component")]

    public class Breadcrumb : System.Web.UI.WebControls.WebControl,
    INamingContainer {

    private HyperLinkCollection mCrumbs;



    Description("An ordered list of links to be displayed")]

    public HyperLinkCollection Crumbs {

    get {

    return this.mCrumbs;



    public Breadcrumb() {

    this.mCrumbs = new HyperLinkCollection();


    /// <summary>

    /// Render this control to the output parameter specified.

    /// </summary>

    /// <param name="output"> The HTML writer to write out to </param>

    protected override void Render(HtmlTextWriter output) {

    output.Write("You are here: ");

    for (int i=0; i<this.mCrumbs.Count; i++) {

    HyperLink l = (HyperLink)this.mCrumbs;


    if (i < this.mCrumbs.Count-1)

    output.Write(" >> ");

    Thanks. It took a little time to figure it out, since the code changes
    didn't show up right away in the designers I'd already created, but got it
    figured out. Thanks again!
