RadioButton inside Ajax UpdatePanel

Hi I have two radio buttons associated with different controls..one with a checked list box and other with a text box. To handle the radio buttons in AJAX, I placed them inside update panel. Overall I placed a table with 2 radio buttons, 1 checked list box, 1 textbox and 2 buttons inside updatepanel. With this approach the radio buttons are working well, but the normal buttons stopped working.

Please find the code below:

XML

<asp:Panel ID="SelectAttributesPanel" runat="server" Width="230px" BackColor="#F0F8FF" BorderColor="Black" BorderWidth="1" Font-Names="Verdana" Font-Size="X-Small" onprerender="SelectAttributesPanel_PreRender">
 <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
 <ContentTemplate>
 <table style="width: 114%; color: #000000;">
 <tr bgcolor="#00CCFF"><td align="left" valign="middle">
 <asp:RadioButton ID="rdSelectAttribs" runat="server" AutoPostBack="True"
Text="Display Exploded View Graph based on the attributes selected below" GroupName="CHOICE" Font-Bold="True" Font-Names="verdana" ForeColor="White" Checked="True" Font-Size="Small" oncheckedchanged="rdSelectAttribs_CheckedChanged" />
</td></tr> <tr><td align="left" valign="middle">
 <asp:CheckBoxList ID="chklstAttributes" runat="server" Font-Names="Verdana" Font-Size="X-Small">
 </asp:CheckBoxList>
</td></tr> <tr bgcolor="#00CCFF"><td align="left" valign="middle">
 <asp:RadioButton ID="rdBaseline" runat="server" AutoPostBack="True"
Text="Display Exploded View Graph based on the RNC Count" GroupName="CHOICE" Font-Bold="True" Font-Names="verdana" ForeColor="White" Font-Size="Small" oncheckedchanged="rdSelectAttribs_CheckedChanged" />
 </td></tr>
<tr><td align="left" valign="middle" style="font-family: verdana; font-size: small;">RNC Count Baseline&nbsp;
 <asp:TextBox ID="txtRNCCountBaseline" runat="server" onKeyPress="return numbersonly(event, false)"
 BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="X-Small" MaxLength="3" Width="26px" EnableViewState="False">50</asp:TextBox></td></tr> <tr><td align="center">
 <asp:Button ID="btnOKSelectAttributes" runat="server" Text="OK" BorderStyle="Solid" BorderWidth="1px"
Font-Bold="True" Font-Size="Small" EnableViewState="False" onclick="btnOKSelectAttributes_Click" CausesValidation="False" Font-Names="verdana" />&nbsp; <asp:Button ID="btnCancelSelectAttributes" runat="server" Text="Close" Font-Bold="True" Font-Size="Small" EnableViewState="False" BorderStyle="Solid" BorderWidth="1px" Font-Names="verdana" />
 </td></tr>
 </table>
 </ContentTemplate>
 <Triggers>
 <asp:AsyncPostBackTrigger ControlID="rdSelectAttribs" EventName="CheckedChanged" />
 <asp:AsyncPostBackTrigger ControlID="rdBaseline" EventName="CheckedChanged" />
 </Triggers>
 </asp:UpdatePanel> </asp:Panel>

In the radio button checked changed events, I enable/disable the checkedlistbox and textbox. They are working fine. But the Ok and Close button events are not firing. What is the problem??

Thank you for your reply.
I got it working by placing the OK and Cancel buttons in separate UpdatePanels. But, I still could not understand why it did not work in a single UpdatePanel.

Hi,
I don't see any event for your close button. However the error is you need to add ok/close button event under trigger, other wise update panel wont response accordingly. Your trigger code should look like this

XML

<Triggers>
<asp:AsyncPostBackTrigger ControlID="rdSelectAttribs" EventName="CheckedChanged" />
<asp:AsyncPostBackTrigger ControlID="rdBaseline" EventName="CheckedChanged" />
<asp:AsyncPostBackTrigger ControlID="btnOKSelectAttributes" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="btnCancelSelectAttributes" EventName="Click" />
 </Triggers>

Hope this will help
