问题描述
我使用了以下代码：
< asp：UpdatePanel ID = UpdatePanel2 runat = 服务器 >
< span class =code-keyword>< ContentTemplate >
< asp：RadioButtonList ID = RadioButtonList1 runat = server
AppendDataBoundItems < span class =code-keyword> = True AutoPostBack = True BackColor = 白色
ForeColor = ＃009999
onselectedindexchanged = RadioButtonList1_SelectedIndexChanged
RepeatDirection = 水平 RepeatLayout < span class =code-keyword> = Flow
< span class =code-attribute>
style = text-align：left;上：407px;左：98px;位置：绝对;宽度：143px;身高：23px; border-style：无 >
< asp：ListItem > 所有者< / asp：ListItem >
< asp：ListItem > 经纪人< / asp：ListItem >
< / asp：RadioButtonList >
< / ContentTemplate >
< / asp：UpdatePanel >
整个页面都刷新了。任何人都可以帮助理清。上述代码没有发生部分页面呈现。
解决方案
您可以将其用于整个页面内容，而不是使用updatepanel到radiobuttonlist。

I used following code:
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:RadioButtonList ID="RadioButtonList1" runat="server"
AppendDataBoundItems="True" AutoPostBack="True" BackColor="White"
ForeColor="#009999"
onselectedindexchanged="RadioButtonList1_SelectedIndexChanged"
RepeatDirection="Horizontal" RepeatLayout="Flow"
style="text-align: left; top: 407px; left: 98px; position: absolute; width: 143px; height: 23px; border-style: None">
<asp:ListItem>Owner</asp:ListItem>
<asp:ListItem>Broker</asp:ListItem>
</asp:RadioButtonList>
</ContentTemplate>
</asp:UpdatePanel>
The whole page is refreshed. Can anyone help to sort out. Partial page rendering is not happening for the above code.
解决方案
Instead of using updatepanel to the radiobuttonlist, you might use it to the entire page content
I hope it will help you to resolve your problem
