DevExpress的DateEdit设置显示日期和时间的方法

1. 设置Mask.EditMask和DisplayFormat,EditFormat属性，设置为一致：'yyyy-MM-dd HH:mm';  //按照想要的显示格式设置此字符串。

this.dateEdit1.Properties.DisplayFormat.FormatString = "yyyy-MM-dd HH:mm";
this.dateEdit1.Properties.DisplayFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
this.dateEdit1.Properties.EditFormat.FormatString = "yyyy-MM-dd HH:mm";
this.dateEdit1.Properties.EditFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
this.dateEdit1.Properties.Mask.EditMask = "yyyy-MM-dd HH:mm";

2. 如果要显示时间需要设置VistaDisplayMode=true, VistaEditTime=true。意思为显示时间，在时间控件中会出现时钟图标，并可以编辑时间。

this.dateEdit1.Properties.VistaDisplayMode = DevExpress.Utils.DefaultBoolean.True;
this.dateEdit1.Properties.VistaEditTime = DevExpress.Utils.DefaultBoolean.True;

3. 设置时间部分的格式，时间部分指的是打开日期空间后，在时钟图标下的显示的日期格式。

this.dateEdit1.Properties.VistaTimeProperties.DisplayFormat.FormatString = "HH:mm";
this.dateEdit1.Properties.VistaTimeProperties.DisplayFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
this.dateEdit1.Properties.VistaTimeProperties.EditFormat.FormatString = "HH:mm";
this.dateEdit1.Properties.VistaTimeProperties.EditFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
this.dateEdit1.Properties.VistaTimeProperties.Mask.EditMask = "HH:mm";

下图为设置后的日期控件
