  Hi
  
  I need rename the root directory dynamically because graphically displays the name as the folder is created on the server.
  
  example, in the server folder called "201109010750", but I need to look at FileExplorer the name "My Files"
  
  thanks!

  Hi Juan,
  
  If I understand you correctly, you need to mask the original name of the root folder to display meaningful name.
  
  The most simple approach to achieve this will be to subclass the default content provider of RadFileExplorer and override its ResolveRootDirectoryAsTree() method and change the Name of the folder, e.g.:
  

  public partial class Default : System.Web.UI.Page

  {

      protected void Page_Load(object sender, EventArgs e)

      {

          RadFileExplorer1.Configuration.ContentProviderTypeName = typeof(CustomContentProvider).AssemblyQualifiedName;

          RadFileExplorer1.Configuration.ViewPaths = new string[] { "~/root" };

      }

  }

   

  public class CustomContentProvider : FileSystemContentProvider

  {

      public CustomContentProvider(HttpContext context, string[] searchPatterns, string[] viewPaths, string[] uploadPaths, string[] deletePaths, string selectedUrl, string selectedItemTag)

          : base(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag)

      {

      }

   

      public override DirectoryItem ResolveRootDirectoryAsTree(string path)

      {

          DirectoryItem orgDir = base.ResolveRootDirectoryAsTree(path);

          if (orgDir.Name.ToLower() == "root")

              orgDir.Name = "ModifiedName";

          return orgDir;

      }

  }

  
  More detailed information on how to use RadfileExplorer's content provider is available in the following help article:
  Using custom FileBrowserContentProvider
  
  For more advanced modification you will need to provide a strong mapping between real folder name and the masked one. Such approach is used in the custom content provider from the following KB article:
  Use RadFileExplorer with physical and shared folder's paths

  Hello,
  
  The searchPatterns property expects a string array of file extensions, e.g.
  
  C#
  RadFileExplorer1.Configuration.SearchPatterns = new string[] { "*.jpg", "*.png", "*.gif" };
  
  VB.NET
  RadFileExplorer1.Configuration.SearchPatterns = New String() {"*.jpg", "*.png", "*.gif"}
  
  so it is up to the developer to write the code that will populate the array with values from a database.
  
  Best regards,
