推荐答案

对于您的情况，您应该使用

Hi,

In your case you should use the

OnDataBinding

事件，并手动绑定数据.

或者您可以将其他项目添加到列表中

event, and manually bind your data.

Or you could add another item to your list

<asp:listitem value="" text="" style="display: none" xmlns:asp="#unknown" />

，它将处理数据库中的空值.


希望这会有所帮助.

and it will handle your empty values from database.


Hope this helps.
