此控件支持如下功能:
1:多文件上传.
2:可以配置最大上传文件个数.
3.自定义js脚本.
4.支持删除已经上传的文件.

参数：
FileName:
Name of the original file, as it is listed on the computer.
FileName_SavedAs:
Path (Directory + Name) that we have given to the file upon storing it to the system (applicable only when having done a Save).
FileName_Path:
Path formatted so that it is accessible by normal HTML.
ContentType:
The MIME type of the content of the file. Useful to filter what types of files we are going to admit. All of the examples are filtered to only
accept GIF images whose ContentType is "image/gif".
Type:
Is an enumerator "FileType" that assists ContentType to ascertain the type of file being dealt with. Basing on the ContentType (never the
extension of the file), allows us to distinguish the following types of files:
image: a file of any image: .gif, .jpg, .png, .bmp, etc.
audio: a file of any audio: .mp3, .wav, etc.
video: a file of general video: .mpg, .avi, etc.
text: a file that can be read like text. Can be flat text, an HTML file, a CSS file, an XML file, etc.
office: files used in the Office series of programs. (Word, Excel, PowerPoint, Access, Publisher, Project, etc.).
zip: ZIP compressed files.
application: Executable files that are not Office or ZIP files.
others: If the ContentType is known, but the file doesn’t match any other listed Type.
unknown: When the ContentType is not known.
ContentLength:
Length (in bytes) of the file. Also useful to limit maximum file size. All of the examples on this website prohibit files larger than 5KB
responseMessage_Uploaded_Saved:
Message that is displayed on screen when a file was successfully saved.
Defaults to:
"<a href="{3}" target="_blank">{0}</a> (>i>{1}>/i>) {2}KB".
Where:
{0} = FileName
{1} = ContentType
{2} = ContentLength
{3} = path for FileName_SavedAs
responseMessage_Uploaded_NotSaved:
Message that is displayed on screen when a file has not been properly stored.
Defaults to: "{0} is not saved." Where {0} = FileName
Saved: Boolean indicating whether the file has been stored correctly or not.
Deleted: Boolean indicating whether the file was deleted after you have uploaded.
responseMessage_Uploaded:
If there have been no changes, this is the message that the user sees after uploading the file. If the file was saved successfully display
“responseMessage_Uploaded_Saved”, otherwise “responseMessage_Uploaded_NotSaved”.
IsRequesting: indicates if a request due to FileUpload AJAX has been initiated. The request can be initiated when a file is uploading or
when it is being erased.
IsPosting: indicates that a file from the FileUpload AJAX control is uploading.
IsDeleting: indicates that a file is being deleted by FileUpload AJAX.
PostedFile: provides access to the HttpPostedFileAJAX that FileUpload AJAX uploaded.
Saving the PostedFile: we have 3 options when we have uploaded the PostedFile, none of which involve using "server.MapPath(...)",
because the control does it automatically:
SaveAs(string path): save the file to the specified path (directory + file name). The results are identical to the SaveAs command in the
standard FileUpload control.
Save(): save the file in the root of our application with the original name.
SaveAs(string directoryPath, string FileName): save the file in the specified directory (directoryPath) and with the specified name
(FileName). A function that is missing from the standard FileUpload control.
