radiobutton click and avoid page refresh<asp:UpdatePanel ID="updAuthoptions" runat="server"> <ContentTemplate> <asp:Panel ID="panelAuthorizationType" runat="server"> <table> <tr> <td> <asp:RadioButton ID="RadioButton1" GroupName="rbAuthType" runat="server" Text="radio 1" OnCheckedChanged="RadioButton1_CheckedChanged" AutoPostBack="true"> </asp:RadioButton> </td> </tr> <tr> <td> <asp:RadioButton ID="RadioButton2" GroupName="rbAuthType" runat="server" Text="radio 2" OnCheckedChanged="RadioButton2_CheckedChanged" AutoPostBack="true"> </asp:RadioButton> </td> </tr> <tr> <td> <asp:RadioButton ID="RadioButton3" GroupName="rbAuthType" runat="server" Text="radio 3" OnCheckedChanged="RadioButton3_CheckedChanged" AutoPostBack="true"> </asp:RadioButton> </td> </tr> </table> </asp:panel> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="RadioButton1" EventName="RadioButton1_CheckedChanged" /> <asp:AsyncPostBackTrigger ControlID="RadioButton2" EventName="RadioButton2_CheckedChanged" /> <asp:AsyncPostBackTrigger ControlID="RadioButton3" EventName="RadioButton3_CheckedChanged" /> </Triggers> </asp:UpdatePanel> Based on the radio button click, I will be enabling/disabling other controls on the page. Now, I want to do the enabling and disabling of controls without the page refresh. However, with the code above, the page refreshes whenever radiobutton1 or radiobutton2 or radiobutton3 is clicked. If I don't set the Autopoastback, the event is not even firing. What wrong am I doing? please help. Thanks! Try adding the following properties to your UpdatePanel:
<asp:UpdatePanel ID="updAuthoptions" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional"> By default, any child controls (anything in the ContentTemplate) are automatically added as Triggers. You can use the ChildrenAsTriggers property to change this. Also, by default the controls in the UpdatePanel are updated on every postback. You can set the UpdateMode property to "Conditional" to specify that it should only be updated when triggered by one of the Triggers. I nearly always use ChildrenAsTriggers="false" and UpdateMode="Conditional" because it gives you more control over the functionality, but depending on the purpose of the pages you are writing your usage may be different. A great book on ASP.NET AJAX, which is where I learned the info I have given you above, is "Introducing Microsoft ASP.NET AJAX" by Dino Esposito from Microsoft Press. Hopefully this helps.

I have the same issue with radio buttons. I tried <asp:UpdatePanel ID="updAuthoptions" runat="server" > ChildrenAsTriggers="false" UpdateMode="Conditional">. My requirement is that another set radiobuttons(in a panel) need to get enabled when an option is chosen from the first radio button list . The page doesn't jump, but then the 2nd set of radiobuttons does not get enabled, although the control goes to its selected index changed event. Could you tell me if I am missing anything?

then, it sounds like you need to use the Triggers control of the UpdatePanel to use the first RadioButtonList as a Trigger. If you post your code I can show you how you should do this for your situation. Good Luck!
