Hide an empty field of Datalist
Apr 02, 2012 05:22 PM|LINK
I have got this datalist with the following fields:Title,Date,Description,Video.
Sometimes there is no record to display for the Video,but cause the width and height of the frame has already been set up
a big blanc space is being shown on the page,how to solve this.
In short how to hide a empty field from the datalist?
here re th codes
<asp:DataList ID="DataList1" runat="server"
DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:Label ID="TitleLabel" runat="server" Text='<%# Eval("Title") %>' />
<br /><asp:Label CssClass="DateLabeldate" ID="DateLabel" runat="server" Text='<%# Eval("Date","{0:dd/MM/yyyy}") %>' />
<asp:Label ID="DescriptionLabel" runat="server" Text='<%# Eval("Paragraph1") %>' />
<br /> <br />
<asp:LinkButton CssClass ="button" ID="LinkButton1" PostBackUrl ='<%# Eval("Id", "actu.aspx?Id={0}") %>' runat="server">lire
plus</asp:LinkButton>
<p><iframe width="600" height="315" src='<%# Eval("VideoUrl") %>' frameborder="0"></iframe></p>

Hello：）
Just put the iframe into the container placer of "div"，and then set the property of "style“——
<div id="bodyframe" style='<%#Eval("VideoUrl")==""?"visibility:hidden":"visibility:show"%>'>
<iframe width="600" height="315" src='<%# Eval("VideoUrl") %>' frameborder="0"></iframe>
</div>
