问题描述

专家，

在listview( lstvwResultInquiry )EditTemplate中，有许多处于编辑模式的控件.

我在oncheckedchanged事件中按下了一个单选按钮，如下所示:

Hi Expert,

In listview(lstvwResultInquiry) EditTemplate there are many controls in edit Mode.

I took one radio button as follows with oncheckedchanged event

<asp:RadioButton ID="radioSource" runat="server" AutoPostBack="True"
                           GroupName="inquiryRadio" oncheckedchanged="radioSource_CheckedChanged" />

并且有一个dropdownlist( lstEditSource )，
例如.

and there is one dropdownlist(lstEditSource) ,
eg.

<asp:DropDownList ID="lstEditSource" runat="server" Width="175px"  Height="23px">

我在 radioSource_CheckedChanged 事件上使用了以下代码来启用dropdownlist(< b> lstEditSource</b>)

I used following code on radioSource_CheckedChanged event to enable dropdownlist(<b>lstEditSource</b>)

if (lstvwResultInquiry.EditIndex > -1)
       {
           DropDownList ddlSource = (DropDownList)lstvwResultInquiry.EditItem.FindControl("lstEditSource");

           ddlSource.Enabled = true;
       }

但ddlSource显示空引用.

如何在单选按钮选中的事件上访问这些editmode listview控件?

在此先谢谢您.

推荐答案

在单选按钮选中的更改事件中使用以下代码

保护虚空......
{
foreach(lstvwResultInquiry.Rows中的GridViewRow grv)
{
DropDownList ddlSource =(DropDownList)grv.FindControl("lstEditSource");


ddlSource.Enabled = true;

}

use the following piece of code in the radiobutton checked change event

protect void ......
{
foreach (GridViewRow grv in lstvwResultInquiry.Rows)
{
DropDownList ddlSource = (DropDownList)grv.FindControl("lstEditSource");


ddlSource.Enabled = true;

}
