OnSelectedIndexChanged事件未触发 [英] OnSelectedIndexChanged event not firing

问题描述

大家好
我在gridview中使用了单选按钮，我只希望选中一个单选按钮，所以我使用了以下代码''

hi all
i used radio buttons in gridview i want only single radio button should be checked so i used following code''

<asp:GridView ID="GridView2" runat="server" ShowHeader="False" AutoGenerateColumns="False"

                   onrowcommand="GridView2_RowCommand"  Width="100%" CellPadding="4"

                   ForeColor="#333333" GridLines="None">

                   <AlternatingRowStyle BackColor="White" />
                   <Columns>
                     <asp:TemplateField>


               <ItemTemplate>
                 
                   <asp:RadioButton ID="rblselect" runat="server" Enabled="true" RepeatDirection="Horizontal"  Width="5px" OnSelectedIndexChanged="rbSelector_CheckedChanged" />
                   </ItemTemplate>

后面的代码

code behind

protected void rbSelector_CheckedChanged(object sender, System.EventArgs e)
       {
           //Clear the existing selected row
           foreach (GridViewRow oldrow in GridView2.Rows)
           {
               ((RadioButton)oldrow.FindControl("rblselct")).Checked = false;
           }

           //Set the new selected row
           RadioButton rb = (RadioButton)sender;
           GridViewRow row = (GridViewRow)rb.NamingContainer;
           ((RadioButton)row.FindControl("rblselect")).Checked = true;
       }

更改单选按钮后，任何人都可以提示我哪里出错了吗?

can any one suggest me where i went wrong event is not firing at all after changing radio button

推荐答案

尝试设置

Try setting the AutoPostback[^] to true.

hi，
您需要像这样将GroupName添加到单选按钮:

hi ,
you need to add the GroupName to the radio button like this:

<asp:radiobutton id="rblselect" runat="server" enabled="true" repeatdirection="Horizontal" xmlns:asp="#unknown">
        Width="5px" OnSelectedIndexChanged="rbSelector_CheckedChanged" GroupName="Radio" /></asp:radiobutton>

表示它只会同时检查一个单选按钮

means it will check only one radio button at the same time

您需要将RadioButton的AutoPostBack属性设置为True.

Hi,

You need to set AutoPostBack Property of RadioButton to True.
