Hi,
Here is the coding i used
<eo:Dialog runat="server" ID="Dialog1" BorderStyle="Solid" CloseButtonUrl="00070101"
MinimizeButtonUrl="00070102" AllowResize="True" ControlSkinID="None" Width="300px"
BorderWidth="1px" Height="200px" ShadowColor="LightGray" BorderColor="#335C88"
RestoreButtonUrl="00070103" ShadowDepth="3" HeaderHtml="Dialog Header" ResizeImageUrl="00020014"
BackShadeColor="Blue">
<HeaderStyleActive CssText="padding-right: 4px; padding-left: 4px; font-size: 11px; background-image: url(00070104); padding-bottom: 3px; padding-top: 3px; font-family: tahoma">
</HeaderStyleActive>
<ContentStyleActive CssText="border-top: #335c88 1px solid; background-color: #e5f1fd">
</ContentStyleActive>
<ContentTemplate>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div style="font-family: Arial; font-size: 10pt;">
<table>
<tr>
<td>
Frist Name:
</td>
<td>
<asp:TextBox ID="txtF1" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
Second Name:
</td>
<td>
<asp:TextBox ID="txtF2" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td colspan="2">
<asp:Button ID="btnJoin" runat="server" Text="Button"
OnClick="btnJoin_Click"></asp:Button>
<asp:Button ID="BtnClose" runat="server" Text="Close"
OnClick="BtnClose_Click"/>
</td>
</tr>
<tr>
<td colspan="2">
<asp:Label ID="lblFull" runat="server"></asp:Label>
</td>
</tr>
</table>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</eo:Dialog>
Problem is my closed button is inside the update panel. under click event i used
Dialog1.InitialState = EO.Web.DialogState.Hidden
