当我单击网格"中的编辑时，出现此错误
无法加载viewstate.加载视图状态的控制树必须与在上一个请求期间用于保存视图状态的控制树匹配.例如，当动态添加控件时，在回发期间添加的控件必须与在初始请求期间添加的控件的类型和位置匹配.
谁能帮助我
WHEN I CLICK ON EDIT IN GRID I GOT THIS ERROR
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
