ASP.NET - how to create folder dynamically and upload zip file from treeview

hi..i have treeview and fileupload controll in my page..now i need to create folders dynamically and upload zip file..i have to delete and rename from selected folder in treeview also...any help???

you just use System.IO namespace and than specify the correct path where you want to create folder and use CreateDirectory method of Directory class as follows


string pathToCreate = "~/UserFolders/" + TextBox1.Text;
if(Directory.Exists(Server.MapPath(pathToCreate))
{
   //In here, start looping and modify the path to create to add a number
   //until you get the value needed
}


//Now you know it is ok, create it
Directory.CreateDirectory(Server.MapPath(pathToCreate));

and for upload zip file simply use Upload control and save posted file from that control to specific folder which you created

hello Friend.

If you want to change the text (rename) of the selected node use:

TreeView1.SelectedNode.Text = "Your new text"

or

You call BeginEdit on the node. Also make sure that the treeview has
LabelEdit set to True

or



 //formats the Text of the menu item
        function formatMenuItem(menuItem, treeNode, formatString)
        {
          var nodeValue = treeNode.get_value();
          if (nodeValue && nodeValue.indexOf("_Private_") == 0)
          {
            menuItem.set_enabled(false);
          }
          else
          {
            menuItem.set_enabled(true);
          }
          var newText = String.format(formatString, extractTitleWithoutMails(treeNode));
          menuItem.set_text(newText);
        }


// to remove

TreeView1.SelectedNode.Remove();

To create folder  use this code-

 try
      {
        // Determine whether the directory exists.
        if (Directory.Exists(path))
        {
          Console.WriteLine("That path exists already.");
          return;
        }

        // Try to create the directory.
        DirectoryInfo di = Directory.CreateDirectory(path);
        Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path));
     
      }
      catch (Exception e)
      {
        Console.WriteLine("The process failed: {0}", e.ToString());
      }

Try this and let me know.

hi

You can use below code to create a folder. But, you need to have enough privileges (impersonation) on the server to create folder

using System.IO;
DirectoryInfo _DicInfo = new DirectoryInfo(@"C:\NewFolder");
if (!_DicInfo.Exists)
{
Directory.CreateDirectory(@"C:\NewFolder");
}

To Zip/UnZip file use this code-

http://www.eggheadcafe.com/community/csharp/2/10401515/how-to-extract-zip-file-using-c.aspx

　

This use code-

A short alternative is ZipStorer (http://zipstorer.codeplex.com/). You don't need to use an external library (.DLL) as it is implemented in one .cs source file.http://zipstorer.codeplex.com/

Extraction example:

// Open an existing zip file for reading
using (ZipStorer zip = ZipStorer.Open(@"c:\data\sample.zip", FileAccesss.Read))
{
// Read the central directory collection
List<ZipStorer.ZipFileEntry> dir = zip.ReadCentralDir();

// Look for the desired file
foreach (ZipStorer.ZipFileEntry entry in dir)
{
if (Path.GetFileName(entry.FilenameInZip) == "sample.jpg")
{
// File found, extract it
zip.ExtractStoredFile(entry, @"c:\data\sample.jpg");
break;
}
}
}
