OnClientProgressUpdating

The OnClientProgressUpdating occurs each time the inline progress indicator is being updated.

note This event is not fired when the RadAsyncUpload uses the IFrame module, for example in IE9 if the control's DisablePlugins property is set to true the RadAsyncUpload will default to using IFrame module, since IE9 does not support File API.

The event handler receives two parameters:

1. The instance of the RadAsyncUpload control firing the event.

2. An eventArgs parameter containing the following method:

• get_row - returns the row whose update indicator has been updated

• get_data - returns data object containing information regarding the progress. The data object contains the following properties:

• percent- returns the percentage of the uploaded file.

• fileSize - returns the file size in bytes.

• fileName - returns the name of the uploading file.

• uploadedBytes - returns the number of uploaded bytes.
