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)); } } |
