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 Ric C,

I tested with modified version that you provided and I can confirm it is working correctly with the latest version of the controls. I would suggest yo to upgrade in order to resolve this issue.

Kind regards,

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">
<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;
        }

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.
