Implements IDataSourceDesigner
- 继承
- 派生
- 实现
示例
下面的代码示例演示如何将自定义数据源控件与其他几个小型自定义类配合使用,如下表所示。
自定义类 | 派生 |
---|---|
CustomDataSource |
ObjectDataSource |
CustomDataSourceDesigner |
DataSourceDesigner |
CustomDataSourceView |
ObjectDataSourceView |
CustomDesignDataSourceView |
DesignerDataSourceView |
BookListViewSchema |
IDataSourceViewSchema |
CustomIDFieldSchema |
IDataSourceFieldSchema |
CustomTitleFieldSchema |
IDataSourceFieldSchema |
BookItem (双字段数据结构。) |
编译代码示例后,在“设计”视图中打开“.aspx”页, DataSourceID
然后将 属性设置为自定义数据源控件的 ID。

注解
类 DataSourceDesigner 是数据源设计器的基类,例如 SqlDataSourceDesigner、 AccessDataSourceDesigner和 ObjectDataSourceDesigner 类。 如果创建新的数据源控件,可能还需要为控件创建自定义控件设计器,并从 类派生它 DataSourceDesigner 。
类 DataSourceDesigner 有两个事件方法: OnDataSourceChanged 和 OnSchemaRefreshed 方法。 这两个事件都可以使用 SuppressDataSourceEvents 设置 SuppressingDataSourceEvents 属性的 方法暂时禁用。 可以使用 方法再次 ResumeDataSourceEvents 启用事件方法。
有两种静态方法可用于评估架构或视图的等效性,而无需创建 类的实例:
方法 SchemasEquivalent 比较两个架构。
方法 ViewSchemasEquivalent 比较两个视图的架构。
继承者说明
若要在设计时为派生类中的操作列表菜单提供命令,必须重写 ActionLists 属性以返回具有派生自 对象的自定义项的DesignerActionList自定义DesignerActionListCollection对象。
