  Requirements
  RadControls version	2009.1.402.35
  .NET version	3.5
  Visual Studio version	2008
  programming language	C#
  browser support	all browsers supported by RadControls

  
  PROJECT DESCRIPTION
  This project encapsulates RadFileExplorer in a user control and extends in with:
  a.) Copy instead of move when you drag a file
  b.) Backup Files when you delete them
  c.) Protect files (disable delete / rename)
  d.) Provide server events for "Folder changed" - "File selected"
  
  The user control (XFileExplorer) has additional parameter as shown here in the code:
  

  <!--

  Supported parameters for XFileExplorer

  ViewPaths="~/XFiles,~/XImages,~/XDocs"      ###parameter for RadFileExplorer

  DeletePaths="~/XFiles,~/XImages,~/XDocs"    ###parameter for RadFileExplorer

  UploadPaths="~/XFiles,~/XImages,~/XDocs"    ###parameter for RadFileExplorer

  BackupURL="/XBackup"    ###path to the backup directory

  BackupEnabled="True"    ###enable backup

  DoCopy="True"           ###copy instead of move

  ProtectedFiles="/XFiles/Styles/XFEStyles.css,/XFiles/Styles/Main.css,/XFiles/Styles/bkg/PageBKG.jpg" ###protected files / diretories

  OnFileSelected="xfeOne_OnFileSelected"      ###event when a file is selected

  OnDirectorySelected="xfeOne_OnDirSelected"  ###event when the current directory has changed

  -->

  <uc1:XFileExplorer ID="xfeOne" runat="server"

  BackupURL="/XBackup"

  BackupEnabled="True"

  DoCopy="True"

  ProtectedFiles="/XFiles/Styles/XFEStyles.css,/XFiles/Styles/Main.css,/XFiles/Styles/bkg/PageBKG.jpg"

  ViewPaths="~/XFiles,~/XImages,~/XDocs"

  DeletePaths="~/XFiles,~/XImages,~/XDocs"

  UploadPaths="~/XFiles,~/XImages,~/XDocs"

  OnFileSelected="xfeOne_OnFileSelected"

  OnDirectorySelected="xfeOne_OnDirSelected" />

  
  Known issues:
  With the trial version of rad controls you get sometimes an error message (see default.aspx).
  This happens (I guess) because the trial version tries to display a message which does not work very well with ajax calls.
  ------
  Sometimes a doubleclick on a folder in the grid (not in the tree) results in an "endless" ajax call.
  Simply choose different folders in the tree (about 2 to 5) and this goes away.
  REASON: when a file or folder is selected I make an ajax call. With a folder RadFileExplorer makes also such a call - and this (if it takes longer to load the directory collides)
  Here is the call which makes the problem:
  

  function OnClientItemSelected(sender, args) {

  var item = args.get_item();

  if (item.get_type() == Telerik.Web.UI.FileExplorerItemType.File) {

  args.set_cancel(true);

  TellServerAboutSelectedElement("FILE:" + item.get_path());

  }

  else {

  //if you want the directory selected in grid as "current directory do this

  //TellServerAboutSelectedElement("DIR:" + item.get_path()); //signal no file selected!!

  //in this case I just want to tell that no file is selected

  //this call sometimes "freezes" RadFileExplorer when a folder is double clicked

  TellServerAboutSelectedElement("FILE:");

  }

  }

  The last line in the function makes the problems sometimes.
  
  How to use the sample:
  Simply open it in visual studio and run it.
  If you run it on a webserver (not the integrated webdev server) ensure that the folders
  /XFiles and /XBackup (including subfolders) have write access for the web server process.

  Have fun
