Hi,

I have a radtabstrip which has sercontrols in it's pageview.

On the usercontrol I have a radiobuttonlist and I want to update a textbox on selection of a radiobutton. Howevere, the code is performing a full postback.

Below is my code.

ASCX:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ucElection.ascx.cs"

Inherits="enrollment_ucElection" %>

<telerik:RadAjaxManagerProxy ID="RadAJAXManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="_ElectionsOptions">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Panel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">

</asp:ScriptManagerProxy>

<table >

<tr>

<td>

<asp:RadioButtonList ID="_ElectionsOptions" runat="server" RepeatDirection="Vertical" AutoPostBack="true" OnSelectedIndexChanged="_ElectionsOptions_SelectedIndexChanged"

RepeatLayout="Flow" />

<asp:Panel ID="Panel1" runat="server" >

<telerik:RadNumericTextBox ID="txtBuyUpPercent" Type="Percent" runat="server">

<NumberFormat DecimalDigits="0" />

</telerik:RadNumericTextBox> (max 10%).

</asp:Panel>

</td>

</tr>

</table>

.CS:

protected void _ElectionsOptions_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (_deferralElectionsOptions.SelectedIndex == 0)
        {
            txtBuyUpPercent.ReadOnly = true;
            txtBuyUpPercent.Text = "";
        }
        else
        {
            txtBuyUpPercent.ReadOnly = false;
        }
    }

Content ASPX page:

<%@ Page Language="C#" MasterPageFile="~/enrollment/enrollmentWizard.master" AutoEventWireup="true"

CodeFile="ELIP.aspx.cs" Inherits="enrollment" Title="Enrollment" %>

<%@ Register TagPrefix="iSys" TagName="insuranceApplication" Src="~/enrollment/ucInsuranceApplication.ascx" %>

<%@ Register TagPrefix="iSys" TagName="deferralElections" Src="~/enrollment/ucElection.ascx" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">

<div>

<telerik:RadTabStrip ID="rtsEnrollment" runat="server" MultiPageID="rmpEnrollment"

OnTabClick="rtsEnrollment_TabClick" SelectedIndex="0" CausesValidation="true"

AutoPostBack="true">

<Tabs>

<telerik:RadTab Text="Deferral Election" PageViewID="ElectionsTab"></telerik:RadTab>

<telerik:RadTab Text="Insurance Application" PageViewID="insuranceApplicationTab"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="rmpEnrollment" runat="server" OnPreRender="rmpEnrollment_PreRender" RenderSelectedPageOnly="true">

<telerik:RadPageView runat="server" ID="ElectionTab" Selected="true">

<iSys:deferralElections ID="ucElection" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="insuranceApplicationTab">

<iSys:insuranceApplication ID="ucInsuranceApplication" runat="server" />

</telerik:RadPageView>

</telerik:RadMultiPage>

</div>

</asp:Content>

RADAjaxManager is declared on the master Page file.

Please suggest what am I doing wrong.

Hi,

Please try to add the RadioButtonList to update itself in the RadAjax settings like this:

<telerik:RadAjaxManagerProxy ID="RadAJAXManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="_ElectionsOptions">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Panel1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="_ElectionsOptions">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="_ElectionsOptions" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

and see how it goes.
