I need to get the tree view WebPart working but I am getting this error: "Error 102 The type or namespace name 'SPFolder' could not be found (are you missing a using directive or an assembly reference?) "
I am using the following References:
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
What am i doing wrong?
