I am using TelerikRadGridview, but I think there is not much difference for my desire.

.XAML:
 
<telerik:RadGridView Margin="22,77,25,0" Name="radGridView1" VerticalAlignment="Top" Height="450" telerik:Theming.Theme="Windows7" CanUserReorderColumns="True">


            <telerik:RadGridView.Columns>
                <telerik:GridViewColumn Header="ImageDisplay">
                    <telerik:GridViewColumn.CellTemplate>
                        <DataTemplate x:Name="dtTemp">
                            <Image x:Name="ImageDisplay2"/>
                        </DataTemplate>
                    </telerik:GridViewColumn.CellTemplate>
                </telerik:GridViewColumn>
            </telerik:RadGridView.Columns>

Open in new window


.CS
 
DomainService1 DS1 = new DomainService1();
            radGridView1.ItemsSource = DS1.Descriptions;
            DS1.Load(DS1.GetDescriptionsQuery());

Open in new window


I want to display Image Column in RadGridview, with URL from the SQL Database.
How can I set Source for this code:

<DataTemplate x:Name="dtTemp">
                            <Image x:Name="ImageDisplay2" Source = HowToSetThisFromDatabase/>
                        </DataTemplate>

Open in new window



The data is binded by using DomainService.


Please help me this problem.

A nice way is to use a converter that takes your URL and returns the image for you.
Check out the article at the DotNetCurry.

Taken from the code in that article (converts stream to image).
public class ImageConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            MemoryStream memStream = new MemoryStream((byte[])value,false);
            BitmapImage empImage = new BitmapImage();
            empImage.SetSource(memStream);
            return empImage; 
        }
 
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

Open in new window


Code can be easily modified to take an URL, read the data as a stream and convert that to the image you need.
