用户界面套包DevExpress v17.2终于正式发布，本站将以连载的形式为大家介绍各版本新增内容。本文将介绍了DevExpress ASP.NET v17.2 的GridView Control、Chart Control、Editors、HTML Editor等新功能，快来下载试用新版本！
在此版本中，WebForms和MVC Scheduler为各种屏幕分辨率提供了改进的支持，其中还包括重新设计自适应模式下的Appointment对话框的布局。Agenda View现在是完全自适应的（包括View Selector和View Visible Interval元素）。

默认情况下，安装WebSphere Application Server时，安装程序会补充说明，在启动时自动运行WebSphere Windows系统服务。在生产服务器上这通常是必要的，但在开发主机上，开始就启动整个应用程序服务器不仅会减慢您的启动，它还会与内部管理的MyEclipse WebSphere发生冲突。因此，您应该禁用此系统服务。
