Using SharePoint CSOM to access a list's information using folder/internal name

Been quite some time since I posted anything but I could not find any place on the net that talked about getting a SharePoint list using the CSOM and the lists internal/folder name.   I finally came up with this kludge using the SPService, but basicly what I am doing is searching the default view URL for the list folder name.

The reason I needed to do this was I had a client request to setup alerts form one list that had URLS that pointed to another list. The alerts really needed to be on the referenced list and not what the user was currently selecting in the list view.

$().SPServices({
    operation: "GetListCollection",
    async: false,
    completefunc: function (xData, Status) {
        $(xData.responseXML).find("List").each(function() {
            if ($(this).attr("DefaultViewUrl").indexOf(listInternalName) >= 0) {
                 listName = $(this).attr("Title");
                 listId = $(this).attr("ID");
            }
        });
    }
});


Hope someone else finds this useful.

How to change the view used by XsltListViewWebPart

So I was in a situation that I needed to change what view was being displayed on a page dynamically.
I am using the the XsltListViewWebPart to display all the values of a list to the user and depending on the user and different properties of the list items I needed to filter the view as well as assign a different XSL file.

The biggest problem I had was that the list view GUID  is created only at deploy time and I could find no other way to assign a different view.

I came across several posts that had examples of changing the view or adding a new XLVWP to the page at deploy time
http://sharepoint.stackexchange.com/questions/4843/reusing-the-xsltlistviewwebpart and http://social.technet.microsoft.com/Forums/zh/sharepoint2010programming/thread/983d2098-d742-4708-8bdc-437aa07b3b9d

So I wanted to take this a little further and be able to dictate what view was used on the fly.  Using a QueryString of the ListID and the ListViewName I then assign the appropriate view in the OnInit event as shown below.


public partial class RecordHistory : DialogLayoutsPageBase
{
     protected void Page_Load(object sender, EventArgs e)
     {
     }
     protected override void OnInit(EventArgs e)
     {
         base.OnInit(e);
         string[] strLists = Request.QueryString.GetValues("ListID");
         string[] strListViewName = Request.QueryString.GetValues("ListViewName");

         if (strLists == null || strLists.Length < 1)
         {
             throw new SPException(SPResource.GetString(Strings.MissingRequiredQueryString, "ListID"));
         }
         SPList spList = SPControl.GetContextWeb(Context).Lists.GetList(new Guid(strLists[0]), true);
         SPView view = spList.Views[strListViewName[0]];
         this.xlvwpRecordHistory.ViewGuid = view.ID.ToString();
         this.xlvwpRecordHistory.ViewId = int.Parse(view.BaseViewID);
         this.xlvwpRecordHistory.XmlDefinition = view.GetViewXml();
     }
}

As always there are many ways to do this that might be better but this worked and I found no other examples of this on the web.
Please let me know if you have a better idea
