Hi geoffrey, i use the example on the web
<body>
<div style="margin: 20px;">
<form id="form1" runat="server">
<cool:ScriptManager ID="ScriptManager1" runat="server" />
<h1>
Window with nested Panel</h1>
<p>
The following example demonstrates how to create a Window with nested controls and
content.</p>
<div style="margin: 15px 0;">
<p>
<asp:Button ID="Button1" runat="server" Text="Show Window" /></p>
<cool:Window ID="Window1" runat="server" Title="Vacation Details" Width="400px" Height="630px"
BodyStyle="padding: 6px;" CloseAction="Hide" Collapsible="True" TriggerElement="Button1"
AnimateTarget="Button1">
<Content>
<cool:Panel ID="Panel1" runat="server" Title="Summary" Height="125px" BodyStyle="padding: 6px;"
Collapsible="True">
<Content>
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</Content>
</cool:Panel>
</Content>
</cool:Window>
</form>
</body>
On CodeBehind I Databind data to GridView1.
Whe I execute in IE or Firefox, over the text "The following example demonstrates how to create a Window with nested controls and content" i could see the gridview borders. When I click the button the window1 show, when i close the borders dessapears.
