I am having trouble with visible attribute of an
ASP.
NET Panel control. I have a page that calls a database table and returns the results in a datagrid.
Requirements
If some of the returned values are null I need to hide the image that's next to it.
I am using a Panel to determine whether to hide or show the image but am having trouble with the statement:
visible='<%# Eval("addr1") <> DBNull.Value %>'
I have tried these as well:
visible='<%# Eval("addr1") <> DBNull.Value %>'
visible='<%# IIf(Eval("addr1") Is DbNull.Value, "False","True") %>'
Code is below:
<asp:TemplateField >
<ItemTemplate>
<%# Eval("Name")%>
<p>
<asp:Panel runat="server" ID="Panel1"
visible='<%# Eval("addr1") <> DBNull.Value %>'>
<asp:Image Id="imgHouse" runat="server"
AlternateText="Address" SkinId="imgHouse"/>
</asp:Panel>
<%# Eval("addr1") %><p>
</ItemTemplate>
</asp:TemplateField>
What am I doing wrong?
Edit
If I use visible='<%# IIf(Eval("addr1") Is DbNull.Value, "False","True") %>'
I get the following error:
Compiler Error Message: CS1026: ) expected
