Return Type

true if the current request was a postback from an HtmlBoxUpload control, false otherwise.

Remarks

The HtmlBox control may have one or many instances of a ToolbarUploadButton on the toolbar. This button launches an "upload" dialog which can be used to upload files to the server via a post request. Use this property to check if the postback to the page was due to an "upload" postback, instead of a standard postback (triggered by a button click, for example).

Requirements

Platforms: Windows 98, Windows NT 4.0, Windows ME, Windows 2000, Windows XP, Windows Server 2003, Windows Vista
