In Menu Control's item collection, setting .Selected=false doesn't work if children present

Discussion in 'ASP .Net' started by Wayne Erfling, Oct 13, 2006.

  1. I put in the code below to disable self links in a menu control in a "master" page.

    It works properly if the top-level menu item has no children, but both ..Selected = false and .NavigateUrl = null are ignored if the top-level menu item has nested (child) menu items.

    This looks like a bug to me, and the documentation for .Selected suggests that it should be possible to disable a higher-level item while leaving the lower levels active.

    Is there something possibly about doing this in PreRender that is letting the menu control ignore the settings? Or could the child entries somehow be re-invigorating the top-level menu items?

    void Page_PreRender(object sender, EventArgs e)
    {
    // Disable self links (this page == NavigateUrl)

    bool bFirstTime = false;
    string [] allPaths;
    string [] PathParts;
    int i;

    MenuItemCollection items = idcMasterMenu.Items;

    PathParts = Request.Path.Split(new char[] {'/'}) ;

    allPaths = (string [])(Session["AllMenuUrls"]);


    if (allPaths == null)
    {
    bFirstTime = true;
    allPaths = new string[items.Count];
    }


    for (i=0; i < items.Count; i++)
    {
    if (bFirstTime)
    allPaths = items.NavigateUrl; // be able to restore if nulled out


    if (items.NavigateUrl.ToLower().IndexOf(PathParts[PathParts.Length-1].ToLower()) > -1)
    {
    items.Selectable = false;
    items.NavigateUrl = null;
    }
    else
    {
    items.Selectable = true;
    items.NavigateUrl = allPaths; // restore from saved values
    }
    }
    if (bFirstTime)
    Session["AllMenuUrls"] = allPaths;

    } // PreRender
