你好朋友， 我在aspx页面中编写了以下代码:

Hello Friends, I have written a following code in my aspx page:

<asp:UpdatePanel runat="server" id="HoodUpdatePane" updatemode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="RBLstSeries" EventName="SelectedIndexChanged"/> </Triggers> <ContentTemplate> <asp:RadioButtonList ID="RBLstSeries" runat="server" onselectedindexchanged="RBLstSeries_SelectedIndexChanged"> <asp:ListItem Text="ELXC" Value="ELXC" Enabled="false"></asp:ListItem> <asp:ListItem Text="ELXC-UVi" Value="ELXC-UVi" Enabled="false"></asp:ListItem> <asp:ListItem Text="ELX" Value="ELX" Enabled="true" Selected="True"></asp:ListItem> <asp:ListItem Text="ELX-UVi" Value="ELX-UVi" Enabled="false"></asp:ListItem> <asp:ListItem Text="PG" Value="PG" Enabled="false"></asp:ListItem> <asp:ListItem Text="VH2" Value="VH2"></asp:ListItem> </asp:RadioButtonList> </ContentTemplate> </asp:UpdatePanel>

但仍然在单选按钮上，单击返回整个页面..我是第一次使用AJAX，请帮助...代码中还需要添加其他内容吗?

but still on radio button click whole page post back..I m using AJAX first time,plz help...anything else has to be added in code?

推荐答案

嘿， 将ur RBLstSeries的AutoPostback属性设置为true 或按照以下内容替换您的代码 Hey, set AutoPostback property true of ur RBLstSeries or replace ur code by following <asp:UpdatePanel runat="server" ID="HoodUpdatePane" UpdateMode="Conditional"> <ContentTemplate> <asp:RadioButtonList ID="RBLstSeries" runat="server" AutoPostBack="True" onselectedindexchanged="RBLstSeries_SelectedIndexChanged" > <asp:ListItem Text="ELXC" Value="ELXC" Enabled="false"></asp:ListItem> <asp:ListItem Text="ELXC-UVi" Value="ELXC-UVi" Enabled="false"></asp:ListItem> <asp:ListItem Text="ELX" Value="ELX" Enabled="true" Selected="True"></asp:ListItem> <asp:ListItem Text="ELX-UVi" Value="ELX-UVi" Enabled="false"></asp:ListItem> <asp:ListItem Text="PG" Value="PG" Enabled="false"></asp:ListItem> <asp:ListItem Text="VH2" Value="VH2"></asp:ListItem> </asp:RadioButtonList> <br /> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> </ContentTemplate> </asp:UpdatePanel>

并在aspx.cs页面中添加以下事件

and in aspx.cs page add following event

protected void RBLstSeries_SelectedIndexChanged(object sender, EventArgs e) { Label1.Text = "Post back Done"; }

希望您的问题得到解决 祝你好运 快乐的编码

hope ur problem is solved best Luck happy coding

RBLstSeries是UpdatePanel的子级，您不需要为其添加AsyncPostBackTrigger.在UpdatePanel上设置ChildrenAsTriggers = true. RBLstSeries is a child of the UpdatePanel, you don''t need to add AsyncPostBackTrigger for it. Set ChildrenAsTriggers=true on the UpdatePanel.

请检查正在执行页面的浏览器.Googlechrome将不支持Ajax. 谢谢， 灰烬 Please check the browser in which you are executing your page.Google chrome wont support Ajax. Thanks, Ashish
