dropdownlist selectedindex事件问题 [英] dropdownlist selectedindex event problem

问题描述

我正在创建使用一个dropdownlist控件的用户控件，我的问题与引发dropdownlist selectedindex事件有关.

Dropdownlist SelectedIndexChangedevent仅在选择first以外的其他项目时触发.

我的意思是，如果我选择第二项SelectedIndexChangedevent事件被调用，但是如果我再次选择第一项，则不会触发SelectedIndexChangedevent事件.

我已经设置了AutoPostBack="true"和EnableViewstate="True".

如果需要其他任何操作，请告诉我.

谢谢，

推荐答案

这可能是一个长镜头，但是您是否将事件绑定到html中?

This might be a long shot, but have you bound the event in the html?

OnSelectedIndexChanged="yourdropdown_SelectedIndexChanged

是的，当然……下拉列表SelectedIndexChangedevent不会在选择第一个项目时被触发，否则工作正常.

Yes offcourse... Dropdownlist SelectedIndexChangedevent does not get fired on selection of item first item else it'' working fine.
