为Ajax 4.0 ComboBox分配onChange事件 [英] Assign onChange Event for Ajax 4.0 ComboBox

问题描述

亲爱的所有人，
我正在使用以下代码动态创建Ajax ComboBox，并且我想使用javascript为comboBox分配onchange事件.即使我分配了onchange事件，也没有任何反应.

Dear All,
I am using below code to create Ajax ComboBox dynamically and I want to assign onchange event using javascript for comboBox. Even I am assigning onchange event but nothing happens.

AjaxControlToolkit.ComboBox cmb = new AjaxControlToolkit.ComboBox();
cmb.RenderMode = AjaxControlToolkit.ComboBoxRenderMode.Block;
cmb.Attributes.Add("onchange", "javascript:alert(this);");
....

我想知道如何使用javascript分配onchange事件"SelectedIndex Change Event"?

I would appreciate to know how to assign onchange event "SelectedIndex Change Event" using javascript?

Thanks.

推荐答案

很抱歉，我错了.我无法为ajaxcontroltoolkit combobox(dll版本3.5)找到OnChange.不确定4.0是否具有该功能.而是尝试使用相同控件的OnSelectedIndexChanged事件.

I am sorry if i am wrong.I am unable to find a OnChange for ajaxcontroltoolkit combobox(dll version 3.5).Not sure if 4.0 has that.Instead try OnSelectedIndexChanged event of same control.
