How to load images in a cell in WPF / UWP TreeGrid?

This example illustrates how to load images in a cell in WPF TreeGrid and UWP TreeGrid (SfTreeGrid).

You can add the image to TreeGrid cell by using TreeGridTemplateColumn.

XAML:

<syncfusion:TreeGridTemplateColumn MappingName="ImageLink">
    <syncfusion:TreeGridTemplateColumn.CellTemplate>
          <DataTemplate>
               <Image Source="{Binding Path=ImageLink,
                      Converter={StaticResource converter}}"/>
          </DataTemplate>
    </syncfusion:TreeGridTemplateColumn.CellTemplate>
</syncfusion:TreeGridTemplateColumn>

C#:

public class StringToImageConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        string imagename = value as string;
        return new BitmapImage(new Uri(string.Format(@"..\..\Images\{0}", imagename), UriKind.Relative));
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return null;
    }
}
