DataView DataView DataView DataView Class

定义

代表 DataTable 的可绑定数据的自定义视图,它用于排序、筛选、搜索、编辑和导航。Represents a databindable, customized view of a DataTable for sorting, filtering, searching, editing, and navigation. DataView 不存储数据,而改为表示对应的 DataTable 的连接视图。The DataView does not store data, but instead represents a connected view of its corresponding DataTable. 更改 DataView 的数据会影响 DataTableChanges to the DataView's data will affect the DataTable. 更改 DataTable 的数据将影响与之关联的所有 DataViewChanges to the DataTable's data will affect all DataViews associated with it.

DataView创建两个对象RowStateFilter , 并将每个对象设置为显示表数据的不同视图。Two DataView objects are created and the RowStateFilter is set on each to show different views of the table data. 然后打印这些值。The values are then printed.

下面的示例将创建DataView按总计LINQ to DataSetLINQ to DataSet排序的联机订单:The following example creates a DataView of online orders ordered by total due from a LINQ to DataSetLINQ to DataSet query:

DataTable orders = dataSet.Tables["SalesOrderHeader"];

EnumerableRowCollection<DataRow> query =
    from order in orders.AsEnumerable()
    where order.Field<bool>("OnlineOrderFlag") == true
    orderby order.Field<decimal>("TotalDue")
    select order;

DataView view = query.AsDataView();

bindingSource1.DataSource = view;
Dim orders As DataTable = dataSet.Tables("SalesOrderHeader")

Dim query = _
    From order In orders.AsEnumerable() _
    Where order.Field(Of Boolean)("OnlineOrderFlag") = True _
    Order By order.Field(Of Decimal)("TotalDue") _
    Select order

Dim view As DataView = query.AsDataView()
bindingSource1.DataSource = view

注解

的主要功能DataView是允许在 Windows 窗体和 Web 窗体上进行数据绑定。A major function of the DataView is to allow for data binding on both Windows Forms and Web Forms.

此外, DataView还可以自定义以显示DataTable中的数据子集。Additionally, a DataView can be customized to present a subset of data from the DataTable. 利用此功能, 您可以将两个控件绑定DataTable到同一个, 但这会显示不同版本的数据。This capability lets you have two controls bound to the same DataTable, but that show different versions of the data. 例如, 一个控件可能绑定到DataView显示表中所有行的, 另一个控件可能配置为仅显示已DataTable从中删除的行。For example, one control might be bound to a DataView that shows all the rows in the table, and a second might be configured to display only the rows that have been deleted from the DataTable. DataTableDefaultView具有属性。The DataTable also has a DefaultView property. 这将返回表DataView的默认值。This returns the default DataView for the table. 例如, 如果要对表创建自定义视图, 请RowFilter DataView在返回DefaultView的上设置。For example, if you want to create a custom view on the table, set the RowFilter on the DataView returned by the DefaultView.

若要创建数据的筛选和排序视图, 请设置RowFilterSort属性。To create a filtered and sorted view of data, set the RowFilter and Sort properties. 然后, 使用Item[Int32]属性返回单个DataRowViewThen, use the Item[Int32] property to return a single DataRowView.

还可以使用AddNewDelete方法在行集中添加和删除。You can also add and delete from the set of rows using the AddNew and Delete methods. 当你使用这些方法时, RowStateFilter属性可以设置为指定只显示已删除DataView的行或新行。When you use those methods, the RowStateFilter property can set to specify that only deleted rows or new rows be displayed by the DataView.

备注

如果未显式DataView指定的排序条件, 则中DataViewDataRowView对象将基于中DataTable.Rows对应DataRow DataRowCollection的 DataView 的索引进行排序。If you do not explicitly specify sort criteria for DataView, the DataRowView objects in DataView are sorted based on the index of DataView's corresponding DataRow in the DataTable.Rows DataRowCollection.

LINQ to DataSetLINQ to DataSet允许开发人员通过使用DataSet LINQLINQ创建复杂、功能强大的查询。allows developers to create complex, powerful queries over a DataSet by using LINQLINQ. DataRow但是, LINQ to DataSetLINQ to DataSet查询返回的是对象的枚举, 但在绑定方案中并不容易使用。A LINQ to DataSetLINQ to DataSet query returns an enumeration of DataRow objects, however, which is not easily used in a binding scenario. DataView可以通过LINQ to DataSetLINQ to DataSet查询创建, 并对该查询进行筛选和排序。DataView can be created from a LINQ to DataSetLINQ to DataSet query and takes on the filtering and sorting characteristics of that query. LINQ to DataSetLINQ to DataSet通过提供DataView LINQLINQ基于表达式的筛选和排序来扩展的功能, 这允许执行比基于字符串的筛选和排序更复杂、功能强大的筛选和排序操作。extends the functionality of the DataView by providing LINQLINQ expression-based filtering and sorting, which allows for much more complex and powerful filtering and sorting operations than string-based filtering and sorting. 有关详细信息, 请参阅数据绑定和 LINQ to DataSetSee Data Binding and LINQ to DataSet for more information.
