ImageButton server control in a Datalist Prob.

[John Stemper]

I've got a problem getting a data element in a Databound datalist to tie in
with an Imagebutton control in the ItemTemplate of the Datalist control.
I've attached the code below. The second dataelement (Name) works fine but
the first one (ImageFileName) doesn't work.
Anyone have any ideas?
TIA
John


<asp:datalist id="dlDesigns" runat="server" HorizontalAlign="Center"
ShowFooter="False" RepeatColumns="3" RepeatDirection="Horizontal"
ShowHeader="False">
<ItemStyle HorizontalAlign="Center"></ItemStyle>
<ItemTemplate>
<asp:ImageButton id="imBtn" runat="server" OnClick="dlSelectEvent"
ImageUrl="/images/<%# DataBinder.Eval(Container,'DataItem.ImageFileName')%">
</asp:ImageButton>
<BR>
Name: <%#DataBinder.Eval(Container, "DataItem.Name") %>
</ItemTemplate>
</asp:datalist>

I just wanted to clarify.. The image path and filename is what I'm trying to
get to appear.

ImageUrl is a server side Property, while the other
item is being written on page prerender, namely after the
code is executed...

That is the difference between those two...


try
ImageUrl='<%# "/images/" + DataBinder.Eval
(Container,"DataItem.ImageFileName").ToString()%>'

it will work i guess..

Hope it helps..

Hello John,

I think the problem exists in the value of ImageURL. You could print our
this string to see if it is correct. At least, you need to put "/images/"
into the <% %> block. Thanks.
