    I am using Radasyncupload and using a customhttphandler and saving files directly to the database. Sometimes the handler is failing because of some error in the code like DB is not available or someother error  and I want to return the exact error message to the application. How can I accomplish this? Any help is much appreciated.

    Hi Rakesh,

    Handle the error in the Handler and return custom result.
    protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration configuration, string tempFileName)
         // Call the base Process method to save the file to the temporary folder
         // base.Process(file, context, configuration, tempFileName);
         // Populate the default (base) result into an object of type SampleAsyncUploadResult
         SampleAsyncUploadResult result = CreateDefaultUploadResult<SampleAsyncUploadResult>(file);
         int userID = -1;
         // You can obtain any custom information passed from the page via casting the configuration parameter to your custom class
         SampleAsyncUploadConfiguration sampleConfiguration = configuration as SampleAsyncUploadConfiguration;
         if (sampleConfiguration != null)
             userID = sampleConfiguration.UserID;
         // Populate any additional fields into the upload result.
         // The upload result is available both on the client and on the server
         result.ImageID = InsertImage(file, userID);
         return result;

    Similar to this online demo:

    I hope this helps.
