推荐答案

这是因为：EnableViewState属性设置为false。

This is because : EnableViewState property set to false.

在ddlsoldrent控件周围放置一个控制面板然后添加一个触发器包含ddlflatshopename的SelectedIndexChanged事件。

Put a control panel around the ddlsoldrent control then add a trigger containing ddlflatshopename's SelectedIndexChanged event.
