注解
Row使用 属性以编程方式访问FormViewRow表示数据行的对象。 数据行包含基于当前模式呈现的模板的不同内容, (属性 CurrentMode) 指定的模板。 对于当前模式,只能访问模板的内容。 下表显示了用于每种模式的模板。
模式 | 呈现的模板 |
---|---|
编辑 | EditItemTemplate |
插入 | InsertItemTemplate |
只读 | ItemTemplate |
备注
只有在 Row 控件在 事件中创建ItemCreated数据行后, FormView 属性才可用。
当需要以编程方式操作数据行时(例如添加自定义内容时),通常使用此属性。 对 属性的任何修改 Row 都必须在 FormView 控件数据绑定后执行;否则,控件 FormView 将覆盖任何更改。
