radlistview中的Asp.net linkbutton没有触发事件

我有一个RadListView，在listview中我有一个asp.net linkbutton . 我想动态设置linkbutton的PostBackUrl . 如果我在listview的ItemDataBound事件中找到linkbutton控件，我可以实现这一点 . 但是，当我最终点击链接按钮时，没有触发listview ItemCommand事件 . 我需要触发itemCommand事件，以便我可以单击项目的datakeyvalue并将其设置为会话变量以传递到链接按钮的postbackurl页面，但是在页面加载时设置postbackurl导致linkbutton不会触发任何事件 .
