推荐答案

也许问题出在_SelectedIndexChanged事件，该事件在页面开始时消失.
问题在这里描述(以及解决方案):

但是除非我查看您的代码(aspx + aspx.cs)，否则对我来说是无知的..

Maybe the problem lies in a _SelectedIndexChanged event, which goes off at the start of the page.
the problem is described here (and the solution too):

But unless I view your code (aspx + aspx.cs) there is no way to know for me..
