Dev系列控件综合实例(分层的提出，异步上传文件)
来源：互联网 发布：正在识别网络 编辑：程序博客网 时间：2024/06/05 09:04
在我的其他随笔中，已经介绍了Dev系列控件的相关数据展示，操作等等。这里主要介绍在数据操作中结合ajax、dev控件、分层进行数据操作,包括对二进制数组文件的上传。
分层的提出
在B/S下进行数据维护，主要包括数据的检索、更新维护。在进行数据更新的时候我们需要结合数据库结构对数据进行校验，这里我使用js结合ajax来调用webservice实现数据校验，校验完毕后，进入数据逻辑层进行相关数据操作。(关于三层架构以及多层架构的文章很多，这里不累赘，只说明结合使用dev控件结合js来进行数据展示层和校验层的操作)
异步实现二进制文件的上传
我们在实现文件上传到数据库的时候，都需要通过相关的上传控件进行，一般的上传控件我们需要在后台进行数据转换成二进制数组。由于上传控件是使用js上传，所以很难通过异步来实现上传(当然优秀的Jquery和定制的可以)。这里通过dev控件中的Uploadcontrol捕捉到uploadcomplete事件，直接得到二进制数组，并将其存入session（由于比较大，在上传入数据库后，我们最好将session清空）。
aspx:
<dxuc:ASPxUploadControl ID="devUploadCode" runat="server" ClientInstanceName="devUploadCode" OnFileUploadComplete="devUploadCode_FileUploadComplete" ShowProgressPanel="True" ShowUploadButton="True"> <UploadButton Text="上传"> </UploadButton><ClientSideEvents FileUploadComplete="function(s, e) { onCodeCompleted(s,e); }" /></dxuc:ASPxUploadControl>
CS：
protected void devUploadWord_FileUploadComplete(object sender, FileUploadCompleteEventArgs e) { Session["WordFile"] = (sender as ASPxUploadControl).UploadedFiles[0].FileBytes; }
下面是详细的代码：
