如何在C#中处理动态组合框selectedIndexchanged事件? [英] how to handle dynamic combo box selectedIndexchanged event in c#?

问题描述

大家好，

我正在动态创建组合框，并将列表绑定到每个组合框.
在函数的SelectedIndexChanged事件中，我正在显示组合框值
到richtextbox.
Richtextbox正确填充了所有组合框值.

但是问题是，每当我从下拉菜单中的任何一个中选择值时，所有下拉菜单中的值都将变为相同的值.

请提出执行此操作的代码逻辑或想法..

在此先感谢!!''

推荐答案

请不要从您动态创建的dropdown对象中获取值.


获取发送方对象，然后键入强制发送方以下拉对象并设置值.从对象中可以获取并设置值.

Please do not get the value from the object of dropdown,which was dynamically created by you.


Get the sender object and type casting the sender to drop down object and set the value. From the object you can get and set the value.
