推荐答案

如果您将属性"AppendDataBoundItems"设置为true，则可以指定ListItem在aspx页面中.从数据库中获取的ListItem将在下面添加.这样，您可以添加数据库中不存在的值.

if you use the property "AppendDataBoundItems" set to true, you can specify the ListItem in the aspx page. The ListItem taken from the database, will be added below. In this way you can add values ​​that are not present in the database.

<asp:dropdownlist appenddatabounditems="true" ...="" xmlns:asp="#unknown">
    <asp:listitem text="All" value="" />
</asp:dropdownlist>
