SharePoint: Finding SharePoint GUIDs


Update… I put together a PowerShell version of this here: http://techtrainingnotes.blogspot.com/2011/06/finding-sharepoint-guids-using.html  (so now you have four versions!)

Update… I put together a version of this that uses the SharePoint web services so you can get the GUIDs without having to be on the server. The EXE and the C# project can be downloaded here.

So now you have three versions, API from a Windows app, API from a LAYOUTs page and Web Services from a Windows app.




Just a little code to share….   :-)


I needed a quick way to find the GUIDs used on a SharePoint site so I wrote a little C# routine to display them. Below is the sample code for both a Windows app and a SharePoint Layouts ASPX page.


The Windows Version:

As this calls the API instead of the web services so this will need to be run from one of the SharePoint servers.

Add a textbox, a button and a listbox on a form then…

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Microsoft.SharePoint;

namespace WindowsApplication2
    public partial class Form1 : Form
        public Form1()
        {  InitializeComponent();    }

        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
            textBox1.Text = listBox1.SelectedItem.ToString();

        private void button1_Click(object sender, EventArgs e)
            SPSite site;
                site = new SPSite(txtSiteURL.Text);
            catch (Exception ex)
            listBox1.Items.Add("Site: " + site.ID.ToString());
            SPWeb web = SPContext.Current.Web;  //site.RootWeb;
            listBox1.Items.Add("Web: " + web.ID.ToString());
            foreach (SPList list in web.Lists)
                listBox1.Items.Add(list.Title + ": " + list.ID.ToString());




The Layouts folder version:

Create a text file in the SharePoint LAYOUTS folder with a name like “getGuids.aspx” and paste the following code. Run the page from any site:  http://youserver/yoursite/_layouts/getGuids.aspx

<%@ Page Language="C#"  %>
<%@ Import Namespace="Microsoft.SharePoint" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
    private void Page_Load(object sender, EventArgs e)
        SPSite site;
        site = SPContext.Current.Site;
        ListBox1.Items.Add("Site: " + site.ID.ToString());
        SPWeb web = SPContext.Current.Web;   // site.RootWeb;
        ListBox1.Items.Add("Web: " + web.ID.ToString());
        foreach (SPList list in web.Lists)
            ListBox1.Items.Add(list.Title + ": " + list.ID.ToString());

    private void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
        TextBox1.Text = Request.Form["ListBox1"];


<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
    <title>Untitled Page</title>
    <form id="form1" runat="server">
        <asp:TextBox ID="TextBox1" runat="server" Width="530px" />
        <br /><br />
        Click to copy to the text box.<br />
        <asp:ListBox ID="ListBox1" runat="server"
          Rows="20" AutoPostBack="True"/></div>

I used the app. Super simple. Thanks a million.

Hmm... worked before, but now I'm getting errors all the time.
"Client found response content type of 'text/html; charset=utf-8', but expected 'text/html'. The request failed with the error message: -- HTML Source of the page that I entered".

The version for _layouts folder doesn't work for me since SPContext.Current.Site is the SiteCollection no matter how deep I'd browse.

Good catch! And an easy fix...

SPWeb web = site.RootWeb;

SPWeb web = SPContext.Current.Web;

(I've updated the code in the article with this change.)

> Client found response content type of 'text/html; charset=utf-8', but expected 'text/html'

That must be from the downloadable copy with the web service call as that error is typically displayed when making a web service call and that call timed out or errored and returned an HTML error message. This could be a permissions issue between your local PC login and SharePoint.

I have posted a PowerShell version of the above here: http://techtrainingnotes.blogspot.com/2011/06/finding-sharepoint-guids-using.html

Tool does work, issue was between keyboard and chair :)

Confirming issue with layouts version being fixed by the correct call to SPContext.Current.Web

Thanks for the timely responses.

Very interesting and usefull I belive, but I'm using Sharepoint 2010 online (Office 365 Enterprise) and I'm struggeling to get any of your alternative solutions for retriving the Site GUID in this environment. Any suggestions?
