I have an ASP.Net RadioButtonList control with AutoPostBack set to true and a server side handler for the SelectedIndexChanged event.

<asp:RadioButtonList runat="server" ID="btnAcceptReject" RepeatDirection="Horizontal" CssClass="checkboxlist borderless" ValidationGroup="data" AutoPostBack="true" OnSelectedIndexChanged="radioButtonList_SelectedIndexChanged">
<asp:ListItem Text="The edition is hereby validated for conformity to standards" Value="0" Selected="True">
</asp:ListItem>
 <asp:ListItem Text="The edition does not meet standards and still has to be reviewed" Value="1"></asp:ListItem>
</asp:RadioButtonList>

<telerik:RadAjaxManagerProxy runat="server" ID="RadAjaxManagerPRoxy1">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="btnAcceptReject">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="pnlControls" />
</UpdatedControls>
 </telerik:AjaxSetting><br></AjaxSettings>

pnlControl is a panel on the page containing controls that will be enabled/disabled depending on which radio button was checked.

the RadAjaxManager never seems to catch the submit event, the above always performs a full postback when one of the radio button of the group is clicked.

Hi ck,

Unfortunately I couldn't replicate the issue at my end. Here is the sample code I tried which works as expected.

MasterPage ASPX:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>
......

Content Page ASPX:
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
    <telerik:RadAjaxManagerProxy ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="btnAcceptReject">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="pnlControls" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>
    <asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="true">
        <asp:ListItem Text="Item1" Selected="True">
        </asp:ListItem>
        <asp:ListItem Text="Item2">
        </asp:ListItem>
    </asp:RadioButtonList>
    <asp:Panel ID="Panel1" runat="server">
        <asp:Label ID="Label1" runat="server">
        </asp:Label>
    </asp:Panel>
</asp:Content>

Thanks,
Princy.

Hi ck,

Please have a look into the sample code in which the RadioButtonList and Panel are inside a UserControl.

ASPX:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>
<uc1:ajaxmanagerproxy ID="ajaxmanagerproxy1" runat="server" />
...

UserControl :
<telerik:RadAjaxManagerProxy ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadioButtonList1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="Panel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>
<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="true">
    <asp:ListItem Text="Item1" Selected="True">
    </asp:ListItem>
    <asp:ListItem Text="Item2">
    </asp:ListItem>
</asp:RadioButtonList>
<asp:Panel ID="Panel1" runat="server">
    <asp:Label ID="Label1" runat="server">
    </asp:Label>
</asp:Panel>

Thanks,
Princy.

                    </asp:Panel>
                </td>
            </tr>
        </tbody>
    </table>
  
</asp:Panel>

and the handler from the code behind

protected void radioButtonList_SelectedIndexChanged(object sender, EventArgs e)
        {
            bool accepted = (sender as RadioButtonList).SelectedValue == "0";
            //disable/enable all controls based on whether the user validates or rejects the review
            txtTitle.Enabled = txtPages.Enabled = txtAbstract.Enabled = dateIssue.Enabled = txtLibraryId.Enabled = txtMarketingBlurb.Enabled = accepted;
            if (!accepted)
                txtTitle.Text = txtAbstract.Text = dateIssue.Text = txtLibraryId.Text = txtMarketingBlurb.Text = txtPages.Text= null;
            vldTitle.Enabled = vldIssueDate.Enabled = vldMarketingBlurb.Enabled = vldAsbtract.Enabled = vldLibraryId.Enabled = vldPages.Enabled = accepted;
        }

this control is hosted inside another user control called BookEditionsControl

<asp:Repeater runat="server" ID="rptEditableEditions" OnItemDataBound="rptEditableEditions_ItemDataBound">
                <ItemTemplate>
                    <div class='bookEditionTab <%# Container.ItemIndex==0? "tab-pane active" : "tab-pane"  %>' id='<%# Eval("Id") %>'>
                        <input type="hidden" id='<%#"hdnLangEditable_"+Eval("Id") %>' value="1" />
                        <uc1:BookEditionCompletionControl runat="server" ID="BookEditionCompletion" WorkMode="<%# WorkMode %>" />
                    </div>
                </ItemTemplate>
            </asp:Repeater>

which in turn is inside a master page where the RadAjaxManager is hosted

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
        </telerik:RadAjaxManager>
  
<uc1:BookEditionsControl runat="server" ID="BookEditions" WorkMode="Edit" />
