    From my searching around, I can't seem to find a definitive answer to this. I want my user-defined method to run once after the Upload button is clicked.

    The FileExplorer ItemCommand event executes with ever file selected (I have EnableAsyncUpload as True). ItemCommand would cause my user-defined method to run per uploaded file, when I only want the method to run after the final upload.

    I tried to keep track of RadFileExplor1.Upload.UploadedFiles.Count, thinking I could execute my method when MyCount == UploadedFiles.Count. The UploadedFiles.Count returns zero (0) on the Page_Load event (when the page is initially opened), but when Page_Load runs again on a postback (after clicking the Upload button), UploadedFiles.Count always throws a null exception.

    So how do I get my method to run once immediately after the Upload button is clicked?

    Thank You,

    Hi Steven,

    You can get the count using From "FileExplorer1.AsyncUpload.UploadedFiles.Count" .Try the code snippets below.

    static int count = 0;
    protected void Page_Load(object sender, EventArgs e)
     count = 0;
    protected void FileExplorer1_ItemCommand(object sender, Telerik.Web.UI.RadFileExplorerEventArgs e)
     if ((FileExplorer1.AsyncUpload != null) && (e.Command.ToString() == "UploadFile"))
      if (count == FileExplorer1.AsyncUpload.UploadedFiles.Count)
       // Your code

    Hope this helps.
