Extended data type (EDT) 属性分为以下几组:

• 对所有EDTs都通用的Common to all EDTs
• 只适用于特定基本类型的Available only for certain base data types

Properties Common to All EDTs

 

Property	Description	New in this version of  Microsoft Dynamics AX
Alignment(对齐)	Changes the alignment of the text (Left, Right, Center).
Analysis- DefaultSort (分析默认排序)	指定在使用该EDT的报表模型中,默认根据该字段排序.
Analysis- DefaultTotal	为度量决定聚合函数. 当 AnalysisUsage 设为 Measure(测量) 时,可以使用该属性. 你可以指定以下值之一. Sum - Returns the sum of all the values in a set. Count - Returns the number of non-null items in a set. CountDistinct - Returns the number of distinct non-null items in a set. Min - Returns the minimum value in a set. Max - Returns the maximum value in a set. None - No aggregate function is applied. Auto - 可应用于派生的EDTs. 将使用父EDT的 AnalysisUsage 属性的值. 聚合函数可以在字段级别被重写.也就是说, 你可以使用 AnalysisDefaultTotal 属性改变要聚合的字段.
AnalysisGrouping	Specifies whether a field that has this EDT is grouped by default when the field is added to a report using the Report Builder for Microsoft SQL Server Reporting Services. The property is automatically set to Discouraged for currency amounts. For other fields that are unique, you should set the property toDiscouraged . For more information about report models, see "Generate and publish report models" in the Help menu for System and Application Setup .
AnalysisUsage	Identifies the role of the EDT in a cube. This setting is automatically propagated to all table fields that reference the EDT. However, the setting can be overridden on the table field. Specify one of the following values. Attribute - A field that references the EDT is a dimension attribute. Measure - A field that references the EDT is a measure. Both - A field that references the EDT is both a dimension attribute and a measure. None - A field that references the EDT is not a dimension attribute and not a measure. Auto - Applies to derived EDTs. The value of the AnalysisUsage property for the parent EDT is to be used.  Note EDTs that are based on enumerations cannot be measures.
ArrayLength (数组长度	只读属性. 默认 ArrayLength 是 1. 要添加数组元素到EDT,右键单击 Array Element 节点,选择 New Array Element . ArrayLength 属性的值会据此增加.
ButtonImage	当EDT用作窗体上的查找按钮时,指定它要显示的图像. The possible values are as follows: Arrow (default) Mail (possible use: the e-mail type) URL (possible use: the URL type) ThreeDots (...) OpenFile (possible uses: the FilenameOpen and FilenameSave types) Calendar (possible use: date types)
CollectionLabel	Specifies the label that is used to display the plural name of a field that has this EDT.
ConfigurationKey	Specifies the configuration key for the EDT.
CountryRegion- Codes	Specifies the country region codes where the menu is applicable or valid. The client uses this property to enable or disable country or region specific features. This is implemented as a comma-separated list of ISO country codes in a single string. The values must match data that is contained in the global address book.	AX 2012
DisplayLength	Specify a maximum number of characters to be displayed in a form or report.
EnumType	Specifies an enumerated data type. If an EDT is of type enum, it is mandatory to set the EnumType property.
Extends	Enables you to base the EDT on another EDT.
FormHelp	Specifies a form that will be used when you perform lookup from a field in a form.
HelpText	Creates a Help string for the EDT. The Help string is displayed when the type is used in a form.
ID	Read-only property.
Label	Specifies a label for the type that is shown when the type is used in a form or report.
Model	Specifies which model the table is in. A model is a logical grouping of elements in a layer. An element can exist in exactly one model in a layer. Examples of elements are a table or class. The same element can exist in a customized version in a model in a higher layer.	AX 2012
Name	Specifies the name of the type. The name is used when it refers to the type from X++.
PresenceClass	Identifies the X++ class that will be used with the PresenceMethod to return a PresenceInfo object instance.	AX 2012
Presence-IndicatorAllowed	Specifies whether the control referencing the EDT will use presence. Default value is Yes .	AX 2012
PresenceMethod	Identifies the X++ static class method in PresenceClass to be called with a controls data value; this returns a PresenceInfo object instance that contains the data needed by the Presence indicator.	AX 2012
ReferenceTable	Identifies the table that is referenced by this EDT, and which has the primary key. Indicates the primary key table which this EDT references.	AX 2012
Style	Changes the default display of the EDT. Options Are: Auto Combo box Radio button	AX 2012
