我在ModalPopupExtender中显示gridview.当屏幕分辨率很小时,弹出窗口将大到全部显示在页面上.

我只想在发生这种情况时向弹出窗口添加滚动条.

我知道它可能是一些CSS,但我尝试的都没有用.

这里有一些基础CSS

.modalTextBoxBackground
{
   background-color:Gray;
   filter:alpha(opacity=70);
   opacity:0.7;
}  
.modalTextBox
{
    border: 1px solid #FFFFFF;
    background-color: #0066CC;
    color: #00FFFF;

}

这里有一些来自aspx的代码

<asp:Panel ID="OptionSelectionPanel" runat="server" CssClass="modalTextBox">
            <asp:UpdatePanel ID="OptionSelectionUpdatePanel" runat="server" UpdateMode="Conditional" >
            <Triggers>
                <asp:asyncPostBackTrigger ControlID="TemplateSelection" />
            </Triggers>
            <ContentTemplate>

            <table class="EditRow">
            <tr class="HeaderFooter">
            <td colspan="3" class="modalTextBoxTitle">
                Add options to Quote
            </td>
            </tr>
            <tr>
            <td>
                Manufacturer
            </td>
             <td>
                <asp:DropDownList ID="OptionManufacturerFilter" runat="server" 
                    DataSourceID="OptionManufacturerDataSource" DataTextField="Name" 
                    DataValueField="Code" AutoPostBack="True" >
                </asp:DropDownList>
            </td>
            </tr>

                            <tr>
            <td colspan="3">
                <asp:GridView ID="NewOptionSelection" 
                              runat="server" 
                              DataSourceID="AvailableOptions" 
                              DataKeyNames="Option_Id"
                              AllowPaging="True" 
                              AllowSorting="True" 
                              AutoGenerateColumns="false">
                <Columns>
                    <asp:BoundField DataField="category_Descr" …

我有以下模态弹出扩展器:

<asp:Label ID="lbl" runat="server"></asp:Label>


                                        <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="lbl"
                                            PopupControlID="PnlUpdate" BackgroundCssClass="modalBackground"  >
                                        </asp:ModalPopupExtender>

                                        <asp:Panel ID="PnlUpdate" runat="server" Width="500px" CssClass="popup" Height="500px" >
                                            <asp:UpdatePanel ID="UpnlModal" runat="server" UpdateMode="Conditional">
