R – Problems adding a DelegateControl to the BlackBand.Master in MOSS 2007

mosssharepoint

I have a custom feature which adds a few controls into the AdditionalPageHead DelegateControl. This works fine on any sites which use our default.master. However the project requires the use of a publishing site which has a master page derived from BlackBand.master (which does not have the AdditionalPageHead DelegateControl included), so I made a copy of the master page from the master page gallery on the appropriate site collection and then modified it to include the following line:

<SharePoint:DelegateControl 
    ID="DelegateControl1" 
    runat="server" 
    ControlId="AdditionalPageHead" 
    AllowMultipleControls="true"/>

This should therefore include this DelegateControl within all pages using this master page. However when this is uploaded as a new version of BlackBand.master and approved as such, all the pages in the site that use it get a 404 error as if they no longer exist. If I restore the previous version of the master page then everything return to normal.

Help is appreciated as always.

The answer was that I was approaching the solution to my problem incorrectly.

To fix this I opened SharePoint designer at my site collection root and clicked on _catalogs/masterpage. Then I made a copy of BlackBand.master in the masterpage catalog. Opened it and added my line of code. Saved it and then set it as my default and custom master page (to ensure that it applied to any straight up web part pages as well as layout pages).

This worked without a problem.

R – MOSS 2007 Breadcrumb problem

After much searching and failing repeatedly I decided to use an AJAX include. Before anyone marks me down for using the devils language (VB.Net) I only used it as I had other developers who were using and maintaing this code so they had to be able to read it...

The include did the following:

split the current url into its constituent parts
For each part get the Sharepoint URL and Sharepoint Web
Print the Title of the sharepoint web
If the part is a page, get the page title and print it

This isnt the final code (i'm going to refactor it tonight):

  Dim lsPage = Request.Item("CurrentPage")
  Dim TravelURL as string = "http://site/"
  Dim aryURLSections() = lsPage.Replace(TravelUrl, "").Split("/")
  Dim i as integer

  Response.Write("<span class='breadcrumbCurrent'>You are in &gt;</span> <span class='ms-sitemapdirectional'><a href='" & TravelUrl & "' title='Home'>Home</a> &gt; </span>")

  for i = 0 to (aryURLSections.Length -1)
    Dim PositionString as string = aryURLSections(i)
    if PositionString.Contains(".aspx") then
        'Render page
        Dim psite as SPSite = new SPSite(TravelUrl)
        Dim pobjSite As SPWeb = psite.OpenWeb() 
        Dim lList as SPList
        Dim lPage As SPListItem
        lList = pobjSite.Lists("Pages")
            If Not lList Is Nothing Then
                For Each lPage In lList.Items
                IF lsPage.ToUpper.Contains(lPage.Url.ToUpper) Then
                Response.Write("<span class='breadcrumbCurrent' >" & lPage.Title & "</span>")
                Else
                'Response.Write("<br>" & lPage.Url & " " & lsPage)
                End If
            Next
        End if
    Else if PositionString.Equals("Pages")
        ' do nothing
    else
        'render site
        TravelUrl = TravelUrl & PositionString & "/"
        'Response.Write(TravelUrl & " > ")
        Dim site as SPSite = new SPSite(TravelUrl)

        Dim objSite As SPWeb = site.OpenWeb()   
        Dim PubWeb = PublishingWeb.GetPublishingWeb(objSite)

        Response.Write("<span class='ms-sitemapdirectional'><a href='" & TravelUrl & "' title='" & PubWeb.Title & "'>" & PubWeb.Title & "</a> &gt; </span>")
    End if

R – Customizing default.master in WSS 3.0

WSS pages use Master Pages just like regular web apps. However, the value if the MasterPageFile attribute is a token, and is set to "~default.master". This token gets replaced with the actual reference to the master page in the page's PreInit method.

You can change the value of ~default.master to anything you like. But a better solution is to do the same type of thing that SharePoint does.

I added an HttpHandler to my SharePoint site. The handler attaches to the PreRequestHandlerExecute method, and changes the value of the master page file attribute before SharePoint starts rendering the page.

Add a line to the httpModules section of the web.config that looks like this:

Then create a class like this:

namespace MyClassLibrary.Utility { public class MasterPageHttpModule : IHttpModule { public void Init(HttpApplication context) { context.PreRequestHandlerExecute += new EventHandler(context_PreRequestHandlerExecute); }

    void context_PreRequestHandlerExecute(object sender, EventArgs e)
    {
        bool useCustomMasterPages = Convert.ToBoolean(ConfigurationManager.AppSettings["ShowCustomMasterPages"].ToString());
        if (useCustomMasterPages)
        {
            Page page = HttpContext.Current.CurrentHandler as Page;
            if (page != null)
            {
                page.PreInit += new EventHandler(page_PreInit);
            }
        }
    }

    void page_PreInit(object sender, EventArgs e)
    {
        bool useThreeColumnMaster = Convert.ToBoolean(ConfigurationManager.AppSettings["UseThreeColumnMasterOnDefaultPage"].ToString());

        try
        {
            Page page = sender as Page;
            if (page != null && SPContext.Current != null)
            {
                string url = page.Request.Url.AbsolutePath.ToLower();
                if (url.IndexOf("/public/") > -1)
                {
                    if (url.IndexOf("sitemap.aspx") == -1)
                    {
                        page.MasterPageFile = "~/_catalogs/masterpage/edge_con.master";
                    }
                    else
                    {
                        page.MasterPageFile = "";
                    }
                }
                else if (url.IndexOf("default.aspx") > -1)
                {
                    if (useThreeColumnMaster)
                    {
                        page.MasterPageFile = "~/_catalogs/masterpage/edge_con.master";
                    }
                    else
                    {
                        page.MasterPageFile = "~/_catalogs/masterpage/edge.master";
                    }
                }
                else if (url.IndexOf("sitemap.aspx") > -1)
                {
                    //
                    //  Sitemap pages should not have a master page
                    //
                    page.MasterPageFile = "";
                    page.Controls.Clear();
                }
                else if (url.IndexOf("/admin/") > -1)
                {
                    page.MasterPageFile = "~/_catalogs/masterpage/edge.master";
                }
                else if (url.IndexOf("/member/") > -1)
                {
                    page.MasterPageFile = "~/_catalogs/masterpage/edge.master";
                }
                else if (url.IndexOf("/supplier/") > -1)
                {
                    page.MasterPageFile = "~/_catalogs/masterpage/edge.master";
                }
                else if (page.MasterPageFile == "~masterurl/default.master")
                {
                    page.MasterPageFile = "~/_catalogs/masterpage/edge.master";
                }
            }
        }
        catch (Exception exception)
        {
            LogWriter logWriter = new LogWriter();
            logWriter.WriteToLog("Could  not set master page: " + exception.Message, LogType.MasterPage, DateTime.Now);
        }
    }

    public void Dispose()
    {
    }
}

}

Now you are dynamically choosing a mater page.
