How to change and image?

[Miguel Dias Moura]

Hello,

i know how to hide a table according to a condition:
<table runat="server" visible='<%# dataSetBibliotecas.FieldValue("Titulo",
Container) <> "" %>'...

Now I am trying to change the image file as follows:
- Show the image "yes.gif" if the value of a dynamic field is equal to
"YES";
- Show the image "no.gif" if the value of a dynamic field is equal to "NO".

Do you think this is possible? Can you help me out?

Thank You,
Miguel

Hi Miguel,

Don't forget that you can use an IIF inside a template item. In the
following code, the IIF checks the value of the "Boolean" field and returns
the English or French button depending on whether the value is true or
false. You could probably adapt this technique to your Yes and No image
locations.

Does this help?
