注解

FormView 控件基于控件的当前模式(由 CurrentMode 属性指定)为数据行呈现不同的模板。The FormView control renders a different template for the data row based on the current mode of the control (specified by the CurrentMode property). 下表显示了用于每个模式的模板。The following table shows which template is used for each mode.

“模式”Mode 模板已呈现Template rendered
编辑Edit EditItemTemplate
InsertInsert InsertItemTemplate
只读Read-only ItemTemplate

FormView 控件处于插入模式时,使用 InsertItemTemplate 属性为数据行定义自己的用户界面(UI)。Use the InsertItemTemplate property to define your own user interface (UI) for the data row when the FormView control is in insert mode. 插入项模板通常包含输入控件,用户可在其中输入新记录的值,以及用于插入记录和取消插入操作的命令按钮。The insert item template usually contains the input controls for the user to enter the values for the new record, as well as command buttons to insert the record and to cancel the insert operation.

若要指定自定义模板,请首先将 <InsertItemTemplate> 标记放在 FormView 控件的开始和结束标记之间。To specify the custom template, first place <InsertItemTemplate> tags between the opening and closing tags of the FormView control. 然后,你可以在开始和结束 <InsertItemTemplate> 标记之间列出模板的内容。You can then list the contents of the template between the opening and closing <InsertItemTemplate> tags. 通过使用双向绑定表达式,你可以将字段与输入控件相关联。By using a two-way binding expression, you can associate a field with an input control. 插入记录后,FormView 控件将自动从关联的输入控件中提取字段值。When a record is inserted, the FormView control automatically extracts the field value from the associated input control. 有关双向绑定表达式的详细信息,请参阅绑定到数据库For more information on two-way binding expressions, see Binding to Databases. 若要创建执行内置取消和插入操作的命令按钮,请将命令按钮控件添加到模板,并将其 CommandName 属性设置为下表中列出的值之一。To create command buttons that perform the built-in cancel and insert operations, add a command button control to the template with its CommandName property set to one of the values listed in the following table.

命令按钮类型Command button type CommandName 值CommandName value
取消Cancel 退出"Cancel"
InsertInsert &"Insert"

您可以使用 InsertRowStyle 属性控制项模板的外观。You can control the appearance of the item template by using the InsertRowStyle property.
