推荐答案

Asp.net下拉列表DataValuefield和datatextfields [ ^ ]



data-text-field-and-data-value-field-pr.aspx [ ^ ]

DataTextField是用户可以看到的。

DataValueField可用于识别从DropDownList中选择哪一个。



例如，您的数据库中有人。在这种情况下，DataValueField可以是人的ID，DataTextField可以是DropDownList中人员的名字。



检查以下内容：

DataValueField [ ^ ]

DataTextField [< a href =http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listcontrol.datatextfield.aspxtarget =_ blanktitle =New Window> ^ ]

DataTextField is what the user can see.
DataValueField is what you can use for identify which one is selected from DropDownList.

For example you have people in your database. In this case the DataValueField can be the ID of the person and the DataTextField can be the name of the person in your DropDownList.

Check the follows:
DataValueField[^]
DataTextField[^]
