Hi,
I have a RadNumericTextBox within an <asp:PlaceHolder>

On page load the <asp:PlaceHolder is not visible. After a series of drop downs within another <asp:PlaceHolder the last drop down set the visibility of the place holder that contains my RadNumericTextBox to true.

this is my RadAjaxManager

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="PhChoice">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PhWithTb" />

</UpdatedControls>

</telerik:AjaxSetting>

When I run this the PnWithTb shows but the validation on the RadNumericTextBox does not work. If I set EnableAjax=False on the RadAjaxManager to false it works fine.

Can any one suggest what I'm doing wrong?

Thanks

Hello Ric C,

I tested the code-below in our latest release and it is working as expected. Please confirm that you use Q2 2011 SP1 (2011.2.915) version?

Aspx:

<telerik:RadAjaxManager ID="ajaxManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Button1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PlaceHolder1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<asp:PlaceHolder runat="server" ID="PlaceHolder1" Visible="false">

<telerik:RadNumericTextBox runat="server" ID="RadNumericTextBox1" />

<asp:Button ID="Button1" Text="submit" runat="server" />

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="RadNumericTextBox1"

ErrorMessage="Required"></asp:RequiredFieldValidator>

</asp:PlaceHolder>

<asp:Button runat="server" ID="Button2" OnClick="Button1_Click" Text="Click to show the PlaceHolder" />

C#:

protected void Button1_Click(object sender, EventArgs e)

{

PlaceHolder1.Visible = true;

}

Hi, Thanks for the quick reply!

Yes your example works (I'm using v.2010.1.309.20), however its not quite what I was looking for. I've updated your code as below. Now the validation is not working on the RadNumericTextBox, any ideas? Thanks!

<telerik:RadAjaxManager ID="ajaxManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Button2">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PlaceHolder1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="Button1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PlaceHolder1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Hi Thanks for the reply.

I was using an old version. I have just downloaded the latest version (demo) to test before purchase, however I am having the same problem with the latest release. If I disable ajax it works fine.

This is the code:
aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="RadTest1._Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js">

</asp:ScriptReference>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js">

</asp:ScriptReference>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js">

</asp:ScriptReference>

</Scripts>

</telerik:RadScriptManager>

<asp:PlaceHolder ID="PhLoader" runat="server"></asp:PlaceHolder>

</div>

</form>

</body>

</html>

aspx.cs

protected void Page_Load(object sender, EventArgs e)

{

Control c = LoadControl("WebUserControl1.ascx");

PhLoader.Controls.Add(c);

}

ascx:

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:RadAjaxManager ID="ajaxManager" runat="server" EnableAJAX="true">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Button2">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PlaceHolder1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="Button1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PlaceHolder1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

[<asp:Literal ID="LitMsg" runat="server"></asp:Literal>]

<asp:PlaceHolder runat="server" ID="PlaceHolder1" Visible="false">

<telerik:RadNumericTextBox runat="server" ID="RadNumericTextBox1" />

<asp:Button ID="Button1" Text="submit" runat="server" />

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="RadNumericTextBox1"

ErrorMessage="Required"></asp:RequiredFieldValidator>

</asp:PlaceHolder>

<asp:Button runat="server" ID="Button2" OnClick="Button1_Click" Text="Click to show the PlaceHolder" />

ascx.cs

protected void Page_Load(object sender, EventArgs e)

{

LitMsg.Text = DateTime.Now.ToLongTimeString();

}

protected void Button1_Click(object sender, EventArgs e)

{

PlaceHolder1.Visible = true;

}

UserControlAjaxManagerValidate.zip

Hi Ric C,

In your code WebUserControl is loaded too late and this is causing the problem. Should load the control on Page_Init instead of Page_Load.

protected void Page_Init(object sender, EventArgs e)

{

Control c = LoadControl("WebUserControl1.ascx");

PhLoader.Controls.Add(c);

}

For your convenience I am attaching modified version of the web site that is working on my end.
