I used following code:

XML

<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.

Solution 1

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
