I had asked this same question a few months ago. This is what someone else suggested

istimezone ? picture one : picture two

<li class="list-group-item"><span class="badge">@(istimezone ?
                    Html.Raw("<img src=\"/Images/closed18.png\" alt=\"image\" />") :
                    Html.Raw("<img src=\"/Images/open18.png\" alt=\"image\" />")
                    )</span>timezone</li>

Hello,

I use the following to show an image based on a condition:

columns: grid.Columns(
        grid.Column(format:
        @<text>
        @if(item.Show == false){
         <a href="~/Admin/GuestBook.cshtml?idShow=@item.gbID" title="Add" ><img src="image.gif" alt="Add" title="Add" /></a>
        }
        </text>
        ),

Great example and it worked, but the 2nd part of the question is how to know the size of the file which is being uploaded.

how to know the size of the file which is being uploaded

If filename is the virtual path on the Web server of your file (e.g. "~/Images/myfile.jpg"),

@using System.IO;

@{
    FileInfo f = new FileInfo(Server.MapPath(filename));
    var fLength = f.Length;
}

 then fLength is the file size in bytes.

The above worked, what would be if the file is in DB.

Generally it's a good habit to store the file size together with the file contents into the same record; for an example look at the Photo Gallery template.

Anyway, you can know the content size of a Sql Server binary field with the t-sql DATALENGTH function. The following query shows file names e dimensions of all files stores in the Photo table of PhotoGallery db (Photo Gallery template):

SELECT FileTitle, DATALENGTH(FileContents) FROM Photos
