BaseDataList 类

定义

用作数据列表控件的抽象基类,如 DataListDataGridServes as the abstract base class for data listing controls, such as DataList and DataGrid. 此类提供由所有数据列表控件公用的方法和属性。This class provides the methods and properties common to all data listing controls.

注解

类提供所有数据列表控件(例如DataListDataGrid)的通用功能。 BaseDataListThe BaseDataList class provides the common functionality for all data listing controls, such as DataList and DataGrid. 数据列表控件用于显示数据源(例如System.Data.DataView控件)中的记录。A data listing control is used to display the records from a data source, such as a System.Data.DataView control. 每个数据列表控件都可以具有唯一的显示样式和功能。Each data listing control can have a unique display style and capabilities. 由于类BaseDataList是抽象的,因此不会直接创建此类的实例。Because the BaseDataList class is abstract, an instance of this class is not created directly. 相反,数据列表控件将继承此类中所有数据列表控件所共有的方法和属性。Instead, data listing controls inherit the methods and properties common to all data listing controls from this class.

通过设置此类的某些属性,可以控制数据列表控件的外观。You can control the appearance of a data listing control by setting certain properties of this class. 若要确定数据列表控件的单元格之间的间距量,请设置CellSpacing属性。To determine the amount of spacing between the cells of a data listing control, set the CellSpacing property. 若要确定单元格内容和单元格边框之间的间距,请设置CellPadding属性。To determine the amount of spacing between the contents of a cell and the cell's border, set the CellPadding property. 通过设置GridLines属性,可以在数据列表控件的各个单元格之间显示边框。You can display the border between the individual cells of a data listing control by setting the GridLines property. 数据列表控件的单元格中内容的水平对齐方式由HorizontalAlign属性控制。The horizontal alignment of the content in the cells of a data listing control is controlled by the HorizontalAlign property.

BaseDataList类提供两个属性以支持数据绑定。The BaseDataList class provides two properties to support data binding. 若要将System.Collections.IEnumerable数据绑定到实现接口的任何集合( System.Data.DataViewIListSourceSystem.Collections.ArrayList DataSource )或接口,请使用属性来指定数据源。To bind data to any collection that implements the System.Collections.IEnumerable interface (such as System.Data.DataView or System.Collections.ArrayList), or the IListSource interface, use the DataSource property to specify the data source. 设置DataSource属性时,必须手动编写代码以执行数据绑定。When you set the DataSource property, you must manually write the code to perform the data binding. 若要自动将数据列表控件绑定到数据源控件所表示的数据源,请使用DataSourceID属性,并将其值设置ID为要使用的数据源控件的属性。To automatically bind a data listing control to a data source represented by a data source control, use the DataSourceID property and set its value to the ID property of the data source control to use. 设置DataSourceID属性时,数据列表控件将自动绑定到指定的数据源控件。When you set the DataSourceID property, the data listing control automatically binds to the specified data source control. 因此,无需显式调用DataBind方法。Therefore, you do not need to explicitly call the DataBind method.

如果由DataSource属性指定的数据源包含多个数据源,请DataMember使用属性指定要绑定到控件的特定源。If the data source specified by the DataSource property contains multiple sources of data, use the DataMember property to specify the specific source to bind to the control. 例如,如果具有System.Data.DataSet包含多个表的对象,则必须指定要绑定到控件的表。For example, if you have a System.Data.DataSet object with multiple tables, you must specify which table to bind to the control. 指定数据源后,使用DataBind方法将数据源绑定到控件。After you have specified the data source, use the DataBind method to bind the data source to the control.

类包含一个DataKeys集合,该集合存储数据列表控件中每条记录的键字段(显示为行)。 BaseDataListThe BaseDataList class contains a DataKeys collection that stores the key field of each record (displayed as a row) in a data listing control. 这样,便可以在不显示控件的情况下,用数据列表控件来存储键字段。This allows you to store the key field with a data listing control without displaying it in the control. Key 字段通常用作更新查询字符串的一部分,用于修改数据源中的特定记录。The key field is commonly used as part of an update query string to revise a specific record in the data source. 集合使用DataKeyField属性所指定的字段中的值进行填充。The collection is filled with the values from the field specified by the DataKeyField property.

类提供当控件SelectedIndexChanged中的选定项发生更改时引发的事件。 BaseDataListThe BaseDataList class provides a SelectedIndexChanged event that is raised when the selected item in the control changes. 这允许您创建一个自定义事件处理程序,该处理程序在引发事件时执行一组特定的指令。This allows you to create a custom event handler that performs a specific set of instructions when the event is raised.
