        <table width="400" bgcolor="#A8CBFF">
        <tr>
            <td class="style4">
                Login Name:</td>
            <td bgcolor="#E4E4E4"><asp:Label runat="server" ID="UserNameLabel" Font-Bold="True"
                    Font-Names="Verdana" ForeColor="Blue" Font-Size="9pt"
                    style="color: #808080; font-size: medium;"></asp:Label></td>
        </tr>
        <tr>
            <td class="style4">
                Approved:</td>
            <td bgcolor="#E4E4E4">
                <asp:CheckBox ID="IsApproved" runat="server" AutoPostBack="true"
                    ForeColor="Blue" Font-Names="Verdana" Font-Size="9pt"
                    style="color: #333333; font-size: medium;"
                    oncheckedchanged="IsApproved_CheckedChanged" />
            &nbsp;<asp:Label ID="StatusMessage" runat="server"></asp:Label>
            </td>
        </tr>
        <tr>
            <td class="style4">
                Locked Out:</td>
            <td bgcolor="#E4E4E4">
                <br />
                <asp:Label runat="server" ID="LastLockoutDateLabel" ForeColor="Red" Font-Names="Verdana" Font-Size="9pt"></asp:Label>
                <br />
                <br />
                <asp:Button runat="server" ID="UnlockUserButton" Text="Unlock User"
                    Font-Names="Verdana" Font-Size="9pt"
                    style="font-size: small; font-family: Tahoma"
                    onclick="UnlockUserButton_Click" BackColor="#666666" BorderColor="#666666"
