Solution 1

RBLstSeries is a child of the UpdatePanel, you don't need to add AsyncPostBackTrigger for it. Set ChildrenAsTriggers=true on the UpdatePanel.

I have removed
<Triggers>
<asp:AsyncPostBackTrigger ControlID="RBLstSeries" EventName="SelectedIndexChanged"/>
</Triggers>
but still it is post back page, I havent written any code in .cs page or I have set AutoPostBack=True for RBTNList?

Solution 2

Please check the browser in which you are executing your page.Google chrome wont support Ajax.

Thanks,

Ashish

Hey,

set AutoPostback property true of ur RBLstSeries
or replace ur code by following

XML

<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>

and in aspx.cs page add following event

C#

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

hope ur problem is solved
