Iterating through SPweb, SPlist and populating Treeview

Following code makes a tree view for a site (web) and its child sites, their lists.
It also displays the number of items each of that list has.

It’s a small Administration utility and very helpful for understanding how to iterate through spsite, spweb and lists.

I used Visual studio 2010. Its great tool to work with SharePoint 2010.
This really a great relied in terms of developing a webpart, packaging and deploying.

I have a user control there I added a tree view, name 'tviewSiteStructure'.

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;

namespace SiteStructure.SiteStructureWebPart
{
public partial class SiteStructureWebPartUserControl : UserControl
{
protected void Page_Load(object sender, EventArgs e)
{

using (SPSite mySite = new SPSite("http://MyMOSS2010/CP"))
{
using (SPWeb myWeb = mySite.OpenWeb())
{

TreeNode mynode = new TreeNode(myWeb.Title, null, null, myWeb.Url, "_self");
TreeNode parentNode = mynode;
tviewSiteStructure.Nodes.Add(mynode);


foreach (SPList myList in myWeb.Lists)
{
string listLink = "" + myList.Title + "(" + myList.Items.Count.ToString() + ")
";

mynode = new TreeNode(listLink, null, null, myList.DefaultViewUrl, "_self");

parentNode.ChildNodes.Add(mynode);

}

foreach (SPWeb childweb in myWeb.Webs)
{
Iterateotherwebs(childweb, parentNode);
}
tviewSiteStructure.CollapseAll();
}
}

}
void Iterateotherwebs(SPWeb web, TreeNode ParentNode)
{
TreeNode mynode = new TreeNode(web.Title, null, null, web.Url, "_self");
TreeNode parentNode = mynode;
tviewSiteStructure.Nodes.Add(mynode);

foreach (SPList myList in web.Lists)
{
string listLink = "" + myList.Title + "("+myList.Items.Count.ToString()+")
";

mynode = new TreeNode(listLink, null, null, myList.DefaultViewUrl, "_self");
parentNode.ChildNodes.Add(mynode);

}

foreach (SPWeb childweb in web.Webs)
{
Iterateotherwebs(childweb, parentNode);
}

}
}

}

error occurred in deployment step 'Retract Solution': The language-neutral solution package was not found

#1
Run Powershell

#2
Ensure you have Sharepoint Powershell commands enabled
For that run following command

Add-PSSnapin Microsoft.SharePoint.Powershell

#3
run following command (Replace mysolution.wsp with your solution name)
(get-spsolution mysolution.wsp).Delete()

this helped to me.
If still not
then open your solution folder and delete files from bin,pkg and obj folders and do the above mentioned again.

SharePoint 2010 build error Warning 1 The Reference...

Warning 1 The referenced assembly “Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c, processorArchitecture=MSIL” could not be resolved because it has a dependency on “System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” which is not in the currently targeted framework “.NETFramework,Version=v4.0,Profile=Client”. Please remove references to assemblies not in the targeted framework or consider retargeting your project.


You may need to do the following to resolve the issue

SharePoint 2010 is built on top of .Net Framework 3.5. So make sure you have it as your targeted framework in VS. Go to project properties and change the target framework to “.Net Framework 3.5″.
