                <fieldset class="CfldFieldSet">
                    <legend>
                        <span style="vertical-align: 14px; font-size: 14px;">Details</span>&nbsp;&nbsp;</legend>
                    <table class="CtblSettings">

                                    UpdateMode="Conditional">
                                    <ContentTemplate>
                                        <asp:Panel ID="pnlCE" runat="server" Width="100%">
                                            <table width="100%">
                                                <tr>

                                                        <CE:Editor ID="ceDescription" runat="server">
                                                        </CE:Editor>
                                                    </td>
                                                </tr>
                                            </table>
                                        </asp:Panel>
                                    </ContentTemplate>
                                </asp:UpdatePanel>
                            </td>
                        </tr>
                        <tr>
                            <td align="center">
                                &nbsp;&nbsp;&nbsp;&nbsp;
                                <asp:Button ID="btnCloseGridInformationDetail" runat="server"
                                    CssClass="CbtnButton" OnClick="btnCloseGridInformationDetail_Click"
                                    Text="Close Cute Editor" />
                            </td>
                        </tr>
                        <tr>
                            <td>
                                &nbsp;</td>
                        </tr>
                    </table>
                </fieldset></asp:Panel>
        </ContentTemplate>
    </asp:UpdatePanel>
     
     
     
     
     
     
    and the code behind in C# is:
     
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            pnlGridInformationDetail.Visible = false;
            updGridInformationDetail.Update();
        }
    }
    protected void btnSearch_Click(object sender, EventArgs e)
    {
        pnlGridInformationDetail.Visible = true;
        updGridInformationDetail.Update();
    }
    protected void btnSaveInformationDetail_Click(object sender, EventArgs e)
    {

    }
    protected void btnCloseGridInformationDetail_Click(object sender, EventArgs e)
    {
        pnlGridInformationDetail.Visible = false;
        updGridInformationDetail.Update();
    }
