## Description

How can I ajaxify Telerik UI for ASP.NET AJAX controls when they are not initially visible on the page?

## Solution

A control which is initially invisible on the page cannot be added to the AjaxManager settings. The initiator or the updated control has to be always placed in a visible container so that the manager can locate it when necessary.

```ASP.NET
<telerik:RadAjaxManager ID="RadAjaxManager2" runat="server">
	<AjaxSettings>
	    <telerik:AjaxSetting AjaxControlID="Button1">
	         <UpdatedControls>
	            <telerik:AjaxUpdatedControl ControlID="Panel1" />
	        </UpdatedControls>
	     </telerik:AjaxSetting>
	</AjaxSettings>
</telerik:RadAjaxManager>
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:Panel runat="server" ID="Panel1">
	<asp:Label ID="Label1" Visible="false" runat="server" Text="Label"></asp:Label>
</asp:Panel>
```
