Hi Mahsa,

You may try this:

<asp:Image
ImageUrl='<%#Server.MapPath(@"\images\roomscenes\"+DataBinder.Eval(Container
..DataItem, "PartNo")+"_ss.jpg") %>' Visible='<%#
System.IO.File.Exists(@"\images\roomscenes\"+DataBinder.Eval(Container.DataI
tem, "PartNo")+"_ss.jpg") %>' runat="server" ID="Image1" />

hi I use th
<asp:Imag
ImageUrl='<%#Server.MapPath(@"\images\roomscenes\"+DataBinder.Eval(Container.DataItem, "PartNo")+"_ss.jpg") %>' Visible='<%#!System.IO.File.Exists(@"\images\roomscenes\"+DataBinder.Eval(Container.DataItem, "PartNo")+"_ss.jpg") %>' runat="server" ID="Image1" /
but it always return visible=fals
when i use
FileInfo fi = new FileInfo(Server.MapPath(@"\images\roomscenes\"+strFileName+"_ss.jpg"))
if (fi.Exists
{do some thing
it shows the currect answer how can I use it in image tag?

Hi Masha,

I'm sorry, but the Server.MapPath call is missing in my sample. The correct
value for the Visible attribute should be

<%#
!System.IO.File.Exists(Server.MapPath(@"\images\roomscenes\"+DataBinder.Eval
(Container.DataItem, "PartNo")+"_ss.jpg")) %>

because the system will net to check for the existence the acual file (on
the physical path, and not the virtual one).

hi I use the
<asp:Image

ImageUrl='<%#Server.MapPath(@"\images\roomscenes\"+DataBinder.Eval(Container
..DataItem, "PartNo")+"_ss.jpg") %>'
Visible='<%#!System.IO.File.Exists(@"\images\roomscenes\"+DataBinder.Eval(Co
ntainer.DataItem, "PartNo")+"_ss.jpg") %>' runat="server" ID="Image1" />

Wrong again... : - (


this shall work:
Visible='<%#
System.IO.File.Exists(Server.MapPath(@"\images\roomscenes\"+DataBinder.Eval(
Container.DataItem, "PartNo")+"_ss.jpg")) %>'

Hi,

One way would be:

<img onerror="fixIt(this)".....

function fixIt(oImg){
oImg.src = "PATH/DEFAULTIMG.gif";
}

If browser has an error loading an image it will use the DEFAULTIMG.gif
just be sure
that the default image is there else endless loop problems
