You should set VisibleOnPageLoad=true when ajax call occurs, or you can handle RadAjaxManager ClientEvents-OnResponseEnd client-side event and show the window via JavaScript, e.g.
ASPX:

    
            <%@ 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>Untitled Page</title> 
        
                <script type="text/javascript">  
        
                function ResponseEnd(obj,args)  
        
                {  
        
                     $find("RadWindow1").show();  
        
                }  
        
                </script> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
        
                <div> 
        
                <asp:RadioButtonList ID="RadioButtonList1" runat="server" 
        
                AutoPostBack="true" 
        
                OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">  
        
                    <asp:ListItem Text="Item1" Selected="True"></asp:ListItem> 
        
                    <asp:ListItem Text="Item2"></asp:ListItem> 
        
                    <asp:ListItem Text="Item3"></asp:ListItem> 
        
                    <asp:ListItem Text="Item4"></asp:ListItem> 
        
                </asp:RadioButtonList> 
        
                <asp:Label ID="Label1" runat="server"></asp:Label> 
        
              <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"   
        
              ClientEvents-OnResponseEnd="ResponseEnd">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadioButtonList1" EventName="SelectedIndexChanged">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadWindow2" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager> 
        
                <telerik:RadWindow ID="RadWindow1" runat="server" NavigateUrl="http://www.google.com" 
        
                VisibleOnPageLoad="false" Left="100"></telerik:RadWindow> 
        
                <telerik:RadWindow ID="RadWindow2" runat="server" NavigateUrl="http://www.yahoo.com" 
        
                VisibleOnPageLoad="false" Left="300">  
        
                </telerik:RadWindow> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

C#:

    
             protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)  
        
                {  
        
                    Label1.Text = System.DateTime.Now.ToString();  
        
                    RadWindow2.VisibleOnPageLoad = true;  
        
                }

Hope this helps

I created a simple example which illustrates how to show RadWindow only when the selected item is with text = "Item2"
ASPX:

    
            <%@ 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>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
        
                <div> 
        
                <asp:RadioButtonList ID="RadioButtonList1" runat="server" 
        
                AutoPostBack="true" 
        
                OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">  
        
                    <asp:ListItem Text="Item1" Selected="True"></asp:ListItem> 
        
                    <asp:ListItem Text="Item2"></asp:ListItem> 
        
                    <asp:ListItem Text="Item3"></asp:ListItem> 
        
                    <asp:ListItem Text="Item4"></asp:ListItem> 
        
                </asp:RadioButtonList> 
        
                <asp:Label ID="Label1" runat="server"></asp:Label> 
        
              <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadioButtonList1" EventName="SelectedIndexChanged">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadWindow2" /> 
        
                            </UpdatedControls>

            </body> 
        
            </html>

C#:

    
             protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)  
        
                {  
        
                    Label1.Text = System.DateTime.Now.ToString();  
        
                    RadWindow2.VisibleOnPageLoad = false;  
        
                    if (RadioButtonList1.SelectedItem.Text == "Item2")

                    }  
        
                }
