The asyncfileupload control is used to asynchronously upload files. For example, refer to: Upload. If you need to upload files asynchronously, refer to the following usage:   Front-end code:   <Ajaxtoolkit: asyncfileupload onclientuploaderror = "uploaderror" onclientuploadcomplete = "uploadcomplete" Runat = "server" id = "asyncfileupload1" width = "400px" uploaderstyle = "modern" Uploadingbackcolor = "# ccffff" Onuploadedcomplete = "asyncfileupload1_uploadedcomplete"/>   Let's talk about attributes, Onclientuploaderror: client Error Handling Method Onclientuploadcomplete: client upload completion event Uploaderstyle: control style, either traditional or modern Onuploadedcomplete: Specifies the storage location and name of a file by calling the saveas method.   Front-end JS Code:   Function uploadcomplete (sender, argS ){ Alert ("uploaded successfully "); } Function uploaderror (sender, argS ){ Alert ("Upload error "); }   Background code:   Protected void asyncfileupload1_uploadedcomplete (Object sender, ajaxcontroltoolkit. asyncfileuploadeventargs E) { Ajaxcontroltoolkit. asyncfileupload fileuploader = sender as ajaxcontroltoolkit. asyncfileupload; If (fileuploader! = NULL & fileuploader. hasfile) { Fileuploader. saveas (server. mappath ("/resource/uploadfile/" + fileuploader. filename )); } }
