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" />
I just found this.
ModalPopupExtender does not show scroll bar
it was still not working, but it was because I use a masterpage, so I solved this using the ClientID
.
(note: to center that inner asp:panel
vertically, the only thing I found was to put it into a Table cell using style="vertical-align:middle"
.
I also need set OptionSelectionTable
's height using JavaScript because height="100%"
fail with some browser.)
<script type="text/javascript">
function pageLoad() {
$get('<%= OptionSelectionPanel.ClientID %>').style.height = document.documentElement.clientHeight * 0.9 + "px";
$get('<%= OptionSelectionTable.ClientID %>').style.height = document.documentElement.clientHeight * 0.9 + "px";
}
</script>
I also had to add the HorizontalAlign="Center"
and ScrollBars="Auto"
and to the Panel ID="OptionSelectionPanel"
(the modalpopup's PopupControlID
).
I moved the CssClass="modalTextBox"
to an inner asp:panel
and restored the HorizontalAlign="Left"
.
<asp:Panel ID="OptionSelectionPanel" runat="server"
HorizontalAlign="Center" ScrollBars="auto">
<asp:UpdatePanel ID="OptionSelectionUpdatePanel"
runat="server"
UpdateMode="Conditional" >
<Triggers>
<asp:asyncPostBackTrigger ControlID="TemplateSelection" />
</Triggers>
<ContentTemplate>
<table ID="OptionSelectionTable"
runat="server"
border="0"
cellpadding="0"
cellspacing="0">
<tr>
<td style="vertical-align:middle">
<asp:Panel ID="OptionSelectionInnerPanel"
runat="server"
HorizontalAlign="Left"
CssClass="modalTextBox">
<table class="EditRow">
......
</table>
</asp:Panel>
</td></tr></table>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
