I've written so many SharePoint asset viewer type web parts (or applications) over the last few years I thought it was about time I blogged some code to get you started yourselves, the following will render a simple treeview that will allow you to traverse through your SharePoint site and sub sites and see what lists, libraries, users etc are in each site.
/// <summary>
/// PopulateTreeView is a recursive function, starting at the supplied SPWeb parameter it will extract all relevant information from the site before recirsing for each sub site.
/// </summary>
/// <param name="web">web is the starting SPWeb (SharePoint web site) for the function. In this case the current site i.e. the site on which the web part is placed.</param>
/// <returns></returns>
protected TreeNode PopulateTreeView(SPWeb web)
{
TreeNode top = null;
if (web != null)
{
//get detail of this current web
top = new TreeNode("Site Details(" + web.Title + ")", "0", "/_layouts/images/SPHOMESM.GIF", web.Url, "_blank");
TreeNode node = new TreeNode(web.Title, "root", "/_layouts/images/ICHTT.GIF", web.Url, "_blank");
node.ChildNodes.Add(new TreeNode("URL: " + web.Url, "", "/_layouts/images/NEWLINK.GIF", web.Url, "_blank"));
TreeNode users = new TreeNode("Users", "", "/_layouts/images/stsicon.gif");
//get all admins
TreeNode admins = new TreeNode("Administrators (" + web.SiteAdministrators.Count + ")", "", "/_layouts/images/STSPEOPL.GIF");
foreach (SPUser user in web.SiteAdministrators)
{
TreeNode usr = new TreeNode(user.LoginName + "(" + user.Email + ")", "", "/_layouts/images/STAR.GIF", "mailto:" + user.Email, "");
admins.ChildNodes.Add(usr);
}
users.ChildNodes.Add(admins);
//get all groups and users within those groups
foreach (SPGroup group in web.Groups)
{
//record this group
TreeNode grp = new TreeNode(group.Name + " (" + group.Users.Count + ")", "", "/_layouts/images/STSPEOPL.GIF");
//for for each user in this group
foreach (SPUser user in group.Users)
{
//record this user
TreeNode usr = new TreeNode(user.LoginName + "(" + user.Email + ")", "", "/_layouts/images/mysite_titlegraphic.gif", "mailto:" + user.Email, "");
grp.ChildNodes.Add(usr);
}
users.ChildNodes.Add(grp);
}
node.ChildNodes.Add(users);
//get all lists (includes document libraries, discussion forums...)
TreeNode lists = new TreeNode("Lists and libraries (" + web.Lists.Count + ")", "", "/_layouts/images/sts_list16.gif");
foreach (SPList list in web.Lists)
{
TreeNode lst = null;
try
{
//an exception can be thrown if an attempt to get the amount of items in a list returns null, also if the list is partially defines an exception may be thrown
lst = new TreeNode(list.Title + " (" + list.ItemCount + " items)", "", "/_layouts/images/iKpiList.png", list.DefaultViewUrl, "_blank");
}
catch(Exception)
{
//if the exception (above) was thrown, just record the name of the list (ignore the amount of items)
lst = new TreeNode(list.Title);
}
lists.ChildNodes.Add(lst);
}
node.ChildNodes.Add(lists);
//recurse for each sub web of the current web
TreeNode webs = new TreeNode("Sub Webs (" + web.Webs.Count + ")", "", "/_layouts/images/SITEVARIATION.GIF");
foreach (SPWeb subweb in web.Webs)
{
webs.ChildNodes.Add(PopulateTreeView(subweb));
}
node.ChildNodes.Add(webs);
top.ChildNodes.Add(node);
}
//return the complete node
return top;
}
