asp.net ModalPopupExtender : need to show scroll bar when overflow
- by DavRob60
I display a gridview in a ModalPopupExtender.
When the screen resolution is to small, the pop-up is to big to all be displayed on the page.
I just want to add scroll bar to the pop-up when this happen.
I know it's probably some CSS, but all I tried did not work.
here some base css
.modalTextBoxBackground
{
background-color:Gray;
filter:alpha(opacity=70);
opacity:0.7;
}
.modalTextBox
{
border: 1px solid #FFFFFF;
background-color: #0066CC;
color: #00FFFF;
}
here some code from the aspx
<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" HeaderText="Category" SortExpression="category_Descr,subcategory_Descr,code" />
<asp:BoundField DataField="subcategory_Descr" HeaderText="Sub-Category" SortExpression="subcategory_Descr,code" />
<asp:BoundField DataField="Manuf_Name" HeaderText="Manufacturer" SortExpression="Manuf_Name"/>
</Columns></asp:GridView>
</td>
</tr>
<tr class="HeaderFooter">
<td colspan="3" class="Center">
<asp:Button ID="OptionSelectionClose" runat="server" Text="Close" />
</td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
<asp:Button runat="server" ID="HiddenTargetControlForOptionSelectionModalPopup" style="display:none"/>
<cc1:ModalPopupExtender ID="OptionSelectionModalPopupExtender" runat="server"
TargetControlID="HiddenTargetControlForOptionSelectionModalPopup"
PopupControlID="OptionSelectionPanel"
BackgroundCssClass="modalTextBoxBackground" />
