Question

I have a GridView that shows information from a building. I am loading the information into the GridView from a database like this:

var buildings = (from t in dc.Towns
                         where (t.userid == userid) && (t.time < DateTime.Now) 
                         join b in dc.Buildings
                             on t.buildingid equals b.buildingid
                             into j1
                         from j2 in j1.DefaultIfEmpty()
                         group j2 by j2.buildingname
                         into grouped
                         select new
                                    {
                                        Building= grouped.Key,
                                        Picture= grouped.First().imagePath,
                                        Number= grouped.Count()
                                    });
        gvBuildings.DataSource = buildings.ToList();
        gvBuildings.DataBind();

But I can’t display the image, it only shows the path where its saved. How can I display the image from the path in the GridView?

Answer 1

You have to have column type that can display image, use Image Field and set DataImageUrlField property with that URL, look here for details:
