ASP.NET Ajax AsyncFileUpload 控件用法

AsyncFileUpload控件,就是用来对文件进行异步上传的,示例看这里:http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/AsyncFileUpload/AsyncFileUpload.aspx。有需要异步上传文件的同学要看这里了,具体用法如下:

 

前台代码:

 

        <ajaxToolkit:AsyncFileUpload OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete"
            runat
="server" ID="AsyncFileUpload1" Width="400px" UploaderStyle="Modern" 
            UploadingBackColor
="#CCFFFF" 
            onuploadedcomplete
="AsyncFileUpload1_UploadedComplete" />

 

说说属性吧,

OnClientUploadError:客户端错误处理方法

OnClientUploadComplete:客户端上传完成事件

UploaderStyle:控件的风格,有传统和现代两种

OnUploadedComplete:服务器端上传完成处理事件,在这个事件中可以调用SaveAs方法,指定文件的存储位置和名称等。

 

前台js代码:

 

        function uploadComplete(sender, args) {
            alert(
"上传成功");
        }

        
function uploadError(sender, args) {
            alert(
"上传错误");
        }

 

后台代码:

 

        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));
            }
        }
