Hi,

The OnFileUploaded event is not firing. Am i missing something?

aspx

<telerik:RadCloudUpload 
                        ID="CU" 
                        runat="server" 
                        MultipleFileSelection="Disabled" 
                        ProviderType="Azure" 
                        MaxFileSize="2147483648"
                        OnFileUploaded="CU_FileUploaded"
                        OnClientUploadFailed="OnClientUploadFailed" 
                        AllowedFileExtensions=".pdf"
                        httpHandlerUrl="~/AzureUploadHandler.ashx">
                    </telerik:RadCloudUpload>

aspx.cs

 protected async void AU_FileUploaded( object sender, Telerik.Web.UI.FileUploadedEventArgs e ) {
            DateTime startDate = DateTime.Now;
            Bll.BfxFiles.SaveFileAsync( Sys.Config.DomainId, 0, 1, e.File.InputStream, e.File.FileName );

            AsyncUploadLabel.ForeColor = System.Drawing.Color.Green;
            AsyncUploadLabel.Text = string.Format( "File '{0}' uploaded successfully to Azure BLOB storage.<br/>Start: {1}<br/>End: {2}<br/>Size: {3}", 
                e.File.FileName, startDate.ToString(), DateTime.Now.ToString(), e.File.ContentLength.ToString() );
        }

handler

<%@ WebHandler Language="C#" Class="AzureUploadHandler" %>

using System;
using System.Web;

public class AzureUploadHandler : Telerik.Web.UI.CloudUploadHandler, System.Web.SessionState.IReadOnlySessionState {
    
    public override void SetKeyName(object sender, Telerik.Web.UI.CloudUpload.SetKeyNameEventArgs e) {
        if ( HttpContext.Current.Session["SelectedBfxFileId"] == null ) {
            HttpContext.Current.Response.Redirect( "~/Login.aspx?m=1" ); // session timed out
        }
        else {
            try {
                int bfxFileId = Convert.ToInt32(  HttpContext.Current.Session["SelectedBfxFileId"] );
                if ( bfxFileId == 0 ) {
                    HttpContext.Current.Response.Redirect( "~/Error.aspx?e=1" ); // invalid bfxFileId
                }
                else {
                    e.KeyName = Bll.BfxFiles.BuildBlobName( bfxFileId, e.OriginalFileName );
                }
            }
            catch ( Exception ex ) {
                throw ex;
            }
        }
    }
}

Hi Vance,

This event will be fired after you cause a postback. Also I have noticed that there is a typo in your markup:
<telerik:RadCloudUpload
                        ID="CU"
                        runat="server"
                        MultipleFileSelection="Disabled"
                        ProviderType="Azure"
                        MaxFileSize="2147483648"
                        OnFileUploaded="CU_FileUploaded"
                        OnClientUploadFailed="OnClientUploadFailed"
                        AllowedFileExtensions=".pdf"
                        httpHandlerUrl="~/AzureUploadHandler.ashx">
                    </telerik:RadCloudUpload>

protected async void AU_FileUploaded( object sender, Telerik.Web.UI.FileUploadedEventArgs e ) {
           DateTime startDate = DateTime.Now;
           Bll.BfxFiles.SaveFileAsync( Sys.Config.DomainId, 0, 1, e.File.InputStream, e.File.FileName );
 
           AsyncUploadLabel.ForeColor = System.Drawing.Color.Green;
           AsyncUploadLabel.Text = string.Format( "File '{0}' uploaded successfully to Azure BLOB storage.<br/>Start: {1}<br/>End: {2}<br/>Size: {3}",
               e.File.FileName, startDate.ToString(), DateTime.Now.ToString(), e.File.ContentLength.ToString() );
       }

Could this be the reason for not firing?

Hi Vance,

You can automatically trigger a postback when the upload finishes by capturing the OnClientFilesUploaded JavaScript event.  That should make fire off the event handler.

Otherwise, add a button that appears, which says something like "Save Uploads" or something. That would also trigger the server side event.
