##### Parameters

Status

  A string value that contains the textual information indicating the current step of the upload. It can take one of the following values:

  Value | Description
  --- | ---
  `START` | The upload process has been started. This value is passed to only for the very first event raising.
  `PREPARE` | Data is being prepared for the upload (thumbnails are generated, request is being constructed, etc). The upload is not started yet.
  `UPLOAD` | Data is being uploaded to the server.
  `WAITING` | Upload has been broken and Image Uploader waits to make attempt to resume the upload.
  `COMPLETE` | The upload process has been successfully completed. This value is passed only once and this is always the very last value for all files uploaded in a single upload session (regardless to the number of packages per one session and number of concurrent connections).
  `CANCEL` | The upload process is cancelled by the user. This value is passed only once and this is always the very last value for all files uploaded in a single upload session (regardless to the number of packages per one session and number of concurrent connections).
  `ERROR` | Some error occurred during the upload. This value is passed only once and this is always the very last value for all files uploaded in a single upload session (regardless to the number of packages per one session and number of concurrent connections). If multiple concurrent connections are used and several of them failed, this value is passed only for the last one.

Progress

  An integer value that contains the degree of completion of the upload or preparation process (in per cents). According to the value of the Status argument the Progress has different meanings:

  Value | Meaning
  --- | ---
  `PREPARE`, `UPLOAD`, or `WAITING` | Percentage of the whole upload process completion (taking into account all packages and concurrent connections in the current upload session).
  `START`, `COMPLETE`, `CANCEL`, or `ERROR` | No meaningful value.

ValueMax

  An integer value that contains the maximum value of the Value argument for the current upload step. Keep in mind, this value may vary for different event handler calls. According to the value of the Status parameter, the ValueMax has different meanings:

  Value | Meaning
  --- | ---
  `PREPARE` | Number of files to be prepared in the current request (package) for the current connection.
  `UPLOAD` | Total size of data of the current request (in bytes).
  `WAITING` | Total number of milliseconds Image Uploader is waiting between upload resume attempts.
  `START`, `COMPLETE`, `CANCEL`, or `ERROR` | No meaningful value.

Value

  An integer value that contains the current value of the progress. Also, if some error occurs, this argument contains the error code. According to the value of the Status argument, the Value has different meanings:

  Value | Meaning
  --- | ---
  `PREPARE` | Number of files in the current request (package) that have already been prepared.
  `UPLOAD` | Amount of bytes of the current request (package) that have already been sent to the server.
  `WAITING` | Number of milliseconds Image Uploader has been waited since the last upload resume attempt.
  `ERROR` | One of the error codes: 1 - number of selected files is less than number of files allowed for the upload; 2 - server, specified in the Action URL was not found (it is down or the server name is misspelled); 3 - URL specified in the Action property has an incorrect syntax; 4 - some server-side error occurred. The StatusText argument contains the server response which can be used for diagnostics; 8 - total size of selected files exceeds the MaxTotalFileSize value; 11 - server returned HTTP code 3xx (e.g. 302 or 304) during redirection. The StatusText contains the URL server redirects to; 12 - the upload was aborted from the script (using the Stop method); 0 - unspecified error.
  `START`, `COMPLETE`, or `CANCEL` | No meaningful value.

StatusText

  A string value that contains the textual information for the current step. According to the value of the Status argument, the StatusText has different meanings:

  Value | Meaning
  --- | ---
  `PREPARE` | Name of the file which is currently being prepared.
  `UPLOAD` | Name of the file which is currently being uploaded to the server.
  `WAITING` | The ProgressDialogWaitingForRetryText property value.
  `COMPLETE` or `ERROR` | Response from the server which is returned by the page files are uploaded to.
  `START` or `CANCEL` | No meaningful value.

# Remarks

This event allows you to handle errors which can occur during the upload, display progress indicator directly in HTML code, detect when the upload is finished, etc.

Keep in mind that this is a through event for whole upload process. Even if you send files in several concurrent upload threads, the total progress is calculated (rather than for individual connection). If you need to know which connection the current event handler call corresponds to, use the CurrentConnectionId property.
