XAF Application Development tutorial-built-in Attribute function list, xafattribute

In the XAF framework, some information used to generate a business application is specified in Attribute. You can apply attributes to a business class (or its members) to specify verification rules, how to display data, and how to set link classes. This topic provides a list of built-in XAF framework attributes and information about where and how these attributes can be applied.

 

Attribute	Description
ActionAttribute	Write the method on the Business Object and add this Attribute to the method. A simple button or window button appears on the interface.
AppearanceAttribute	Write this Attribute on the business class or Method \ Attribute to control the appearance control, such as whether the control is disabled, whether it is read-only, whether the background color changes, Font, And button are available.
Aggrespondattribute	Write on the properties of the XPCollection <T> type to control whether the business pairs in the master-slave table structure are aggregated. What aggregation? It means that the primary object and the sub-object are put together and correspond to a business content, such as orders and order details. The two tables are put together completely.
CalculatedAttribute	The result of the attribute is calculated.
CalculatedPersistentAliasAttribute	Applied to a business class. Allows you to dynamically configure a persistent alias for the target business class 'Property.
CaptionsForBoolValuesAttribute	In a Boolean attribute, you can specify true or false as the specified value. For example, if the value is changed to male or female, true or false, yes or no. but do not use it as a Chinese version.
CodeRuleAttribute	Applied to a validation rule. Specifies that the rule is intended for a participating business class and does not have a corresponding validation attribute.
CollectionSourceModeAttribute	Specifies the mode of operation for the Collection Sources created by List Property Editors representingCollectionSourceModeAttribute'S target property.
CreateInstanceAttribute	Specifies that a Domain Component's target method will create Domain Component instances.
CreatableItemAttribute	It is written on BO/DC, which is not the same as that under win on the web. You can quickly create a menu to display this BO.
CriteriaOptionsAttribute	When using the condition editor, specify some options here, for example, which BO the condition applies.
DataSourceCriteriaAttribute	It can be applied to BO-type attributes, or to an XPCollection <T>. It specifies the criteria used to filter data sources when a (Link, Link) object is selected. For example, a customer attribute exists, when selecting a customer, all customers aged between 30 and 50 must be displayed in a specific scenario.
DataSourceCriteriaPropertyAttribute	This is the same as the above function, but this condition is not written to death and has been read from another attribute. This allows for dynamic receiving conditions in that attribute.
Cecepropertyattribute	Function and the above two types, but it is more dynamic to directly specify the data source that can be selected from a certain attribute, but it is better to consider performance issues, because the programmer spelled out the data source, i'm not sure how I got it.
DefaultClassOptionsAttribute	After adding this, BO will appear in the navigation bar, and the quick create button will also appear in the report. I only observed so much. This is a shortcut.
DefaultListViewOptionsAttribute	Write on BO, some common default list view control.
DelayedAttribute	Write on the attribute and delay loading this attribute. EF is officially used, but I have also used it in xpo!
DetailViewLayoutAttribute	Write on attributes for simple layout of detailed views on BO.
DomainComponentAttribute	Writing on the Interface indicates that this is a DC. Writing on non-persistent BO indicates that the system will generate the view of this BO.
ExpandObjectMembersAttribute	You can describe the attributes of a complex type to show them in the view. for example, the customer. address. the detailed address has a bunch of properties at the same level as the detailed address. After using this, you can display it all at once.
FieldSizeAttribute	The length of the field created in the library for the struct attribute.-1 is not long.
FileAttachmentAttribute	If the value is of the file type and is applied to the class, the IFileData interface must be implemented.
FileTypeFilterAttribute	How do I filter file names when uploading files? Extension?
FriendlyKeyPropertyAttribute	Specifies a property that is considered an analog ofGUIDProperty to allow the use of more suitable values.
ImageEditorAttribute	Image editor settings.
ImageNameAttribute	Write it on BO and set an icon. This icon is displayed on the list and detailed view.
ImagesForBoolValuesAttribute	You can specify a Boolean icon on a Boolean attribute. For example, if the value is true, a pair is used. If the value is false, a cross is used.
ImmediatePostDataAttribute	Useful in the web, written in attributes, indicates whether to send the value back to the server when the value changes, for example, when the total price = unit price * quantity, then, unit, and quantity change, the total price needs to be calculated, so we need to add this Attribute to the unit price and quantity.
IndexAttribute	Write the attribute above. When creating a table, create an index to capture performance.
KeyAttribute	The attribute indicates that this attribute is the primary key.
ListEditorAttribute	Specifies the list control to be used.
ListViewFilterAttribute	A drop-down box is displayed on the interface with some built-in filtering conditions for the list.
LookupEditorModeAttribute	Indicates what the Search dialog box looks like. For example, if all the items are displayed in the drop-down box, a window is displayed, or an automatic dialog box is displayed. If there are more than 25 items automatically displayed, the dialog box is displayed. this will automatically affect the performance, because the current number of data records needs to be calculated.
ModelDefaultAttribute	Write the default value in ModelEditor in the Code. Many Dongdong can use this setting and can replace some previous attributes. For example, you can use [XafDisplayName ("display name")] change to [ModelDefault ("Caption", "display name")]. you can open ModelDeditor to check the keyword Caption.
ModelNodesGeneratorAttribute	Write a class by yourself to generate the model. You need to add this. The specific steps are required.
NavigationItemAttribute	Whether a BO is displayed in the navigation bar.
NonCloneableAttribute	Clone module: This BO clone is not allowed.
NotClonedInfoAttribute	Applied to a business class. Specifies a business class 'string property that can hold property values that were not cloned.
ObjectCaptionFormatAttribute	Indicates the title of Bo in the Details View.
PropertyEditorAttribute	The default editor is automatic. You only need to change the default editor.
Attributes from the Validation module: RuleBaseAttribute, RuleCombinationOfPropertiesIsUniqueAttribute, RuleCriteriaAttribute, RuleFromBoolPropertyAttribute, RuleIsReferencedAttribute, RuleObjectExistsAttribute, RuleRangeAttribute, RuleRegularExpressionAttribute, RuleRequiredFieldAttribute, RuleStringComparisonAttribute, RuleUniqueValueAttribute, RuleValueComparisonAttribute.	These are all used for verification rules. The combination of RuleCombinationOfPropertiesIsUniqueAttribute is unique. Multiple Attributes are specified on the class. These attributes are unique in combination. RuleCriteriaAttribute. in the class, the data must meet the specified conditions. RuleFromBoolPropertyAttribute. The value must be true in a Boolean attribute. RuleObjectExistsAttribute, the specified object must exist. RuleRangeAttribute. The attribute value must be within the specified range. RuleRegularExpressionAttribute. The attribute value must meet the requirements of regular expressions. RuleRequiredFieldAttribute. The attribute is required. RuleStringComparisonAttribute. The attribute value is compared with the string. RuleUniqueValueAttribute. The attribute value must be unique. RuleValueComparisonAttribute. The attribute value is compared with the specified value (another attribute.
SearchClassOptionsAttribute	Some options for full-text search.
SearchMemberOptionsAttribute	It is also used for full-text search. It specifies the fields involved or not involved.
ToolTipAttribute	Prompt text of the attribute.
ViewItemAttribute	Applied to a custom View Item. Registers a View Item in an application and specifies the type of the Application Model's node used by a custom View Item.
VisibleInDetailViewAttribute	Whether the attribute is visible in the Details View
VisibleInListViewAttribute	Whether the attribute is visible in the List View
VisibleInLookupListViewAttribute	Whether the attribute is visible in the search view.
VisibleInReportsAttribute	Can I select this BO when making a report.
Xafdefaproperpropertyattribute	Default attribute. When the reference type is used for the attribute, the field of the reference class is used as the display title. for example, after selecting a customer in the order, the customer name should be displayed. Then [xafdefadefapropety ("name")] should be written on the customer's BO.
XafDisplayNameAttribute	Specify the display name, for example, "BO" is "Customer", "XafDisplayName" ("Customer") "], and write it to" BO.

You can also use some attributes provided by. net (such as BrowsableAttribute and DefaultPropertyAttribute DisplayNameAttribute)

The following list is in the System. ComponentModel namespace, and they are valid in XAF.

Attribute	Description	Remarks
BrowsableAttribute	Whether the attribute is visible. If it is set to false, the Details View, list view, and search view are invisible. This is equivalent to a shortcut.	It is usually used to hide an attribute.
DefaultPropertyAttribute	It is the same as xafdefaproperpropertyattribute .: Displayed in the search editor; Object title, such as in the detailed view; Full-text search will also be used; The first column is displayed in the List View.
DescriptionAttribute	Remarks of the. indicator module will be used for custom modules.
DisplayNameAttribute	Same as XafDisplayNameAttribute.
PasswordPropertyTextAttribute	In the string attribute, the editor is changed to the password input box.
