/*******************快速使用*************************/

定好保存路径

设置控件的fileuploadcomplete事件

 

using System.IO;
using DevExpress.Web.ASPxUploadControl; 
 #region 上传文件
    ///

    /// 保存上传文件
    ///

    ///
    ///
    protected string SavePostedFiles(UploadedFile uploadedFile)
    {
        //保存至服务器上的路径
        fangqm.Netbank.Core.Savepath savepath = new fangqm.Netbank.Core.Savepath();
        UploadDirectory = savepath.getuploadfileSavePath(DateTime.Now.ToShortDateString());
        if (!Directory.Exists(Server.MapPath(UploadDirectory)))
        {
            Directory.CreateDirectory(Server.MapPath(UploadDirectory));
        }

        string ret = "";
        if (uploadedFile.IsValid)
        {  //显示进度
            FileInfo fileInfo = new FileInfo(uploadedFile.FileName);
            string resFileName = MapPath(UploadDirectory) + fileInfo.Name;
            uploadedFile.SaveAs(resFileName);

            string fileLabel = fileInfo.Name;
            string fileType = uploadedFile.PostedFile.ContentType.ToString();
            string fileLength = uploadedFile.PostedFile.ContentLength / 1024 + "K";
            ret = string.Format("{0}({1}){2}|{3}", fileLabel, fileType, fileLength, fileInfo.Name);
        }
        return ret;
    }
    protected void ASPxUploadControl1_FileUploadComplete(object sender, FileUploadCompleteEventArgs e)
    {
        try
        {
            e.CallbackData = SavePostedFiles(e.UploadedFile);
        }
        catch (Exception ex)
        {
            e.IsValid = false;
            e.ErrorText = ex.Message;
        }
    }

    #endregion

ValidationSettings属性下，可以设置上传文件大小（字节），文件类型，文件扩展名
设置上传文件大小（字节）MaxFileSize="4000000"
文件类型     AllowedContentTypes="image/jpeg,image/gif,image/pjpeg"
文件扩展名   AllowedFileExtensions=".jpg,.jpeg,.jpe,.gif"

 

如果使用中发现取不到服务器控件如aspxtextbox值,可以将其FileUploadMode="OnPageLoad"即可
