I am using dynamic ItemTemplate for ListView which populated from database.Here is how I do when I need to display string column “Parametr” (or some other datatypes):

     //my .ascx file
     <li><%# Eval("Parametr") %> </li>

How can I display varbinary column that stores images?Thanks.

EDIT:

Here is some more code if somebody needed:

<asp:ListView ...  DataSourceID="database"   ></asp:ListView>
<asp:SqlDataSource ... ID="database" SelectCommand="SELECT image FROM image_table"></asp:SqlDataSource>

    You could use an “inline image”. The technique is described at for instance Base64 encoded images embedded in html (search for base64 image html for other resources).

    Get the base64-encoded string of the image data bytes, using Convert.ToBase64String for instance, and then use <img src=data:image/gif;base64, and append the image data.

    So you can bind it using something like this

    <img src='<%# string.Format("data:image/gif;base64,{0}",
 Convert.ToBase64String((byte[])Eval("ImageDataBase64")))%>'/>

    Of course, this is only recommended for small images. Also note that you should change “gif” to the actual format of your image.
