+This example illustrates how to load images in a cell in [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) and [UWP TreeGrid](https://www.syncfusion.com/uwp-ui-controls/treegrid).
+
+You can add the image to `TreeGrid` cell by using `TreeGridTemplateColumn`.
+
+## XAML code:
+
+``` xml
+<syncfusion:TreeGridTemplateColumn MappingName="ImageLink">
+    <syncfusion:TreeGridTemplateColumn.CellTemplate>
+          <DataTemplate>
+               <Image Source="{Binding Path=ImageLink,
+                      Converter={StaticResource converter}}"/>
+          </DataTemplate>
+    </syncfusion:TreeGridTemplateColumn.CellTemplate>
+</syncfusion:TreeGridTemplateColumn>
+```
+
+## c# code:
+
+``` 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;
+    }
+}
+```
