Custom editor property grid memory leak

Question

Hi,
 
                I’m using Syncfusion custom editor to bind to the property grid. Please find the code below,
 
Code snippet:
 
public class eFormColorEditor : ITypeEditor
    {
        private ColorPickerSelector brushSelector;
        #region ITypeEditor Members
 
        public void Attach(PropertyViewItem property, PropertyItem info)
        {
            if (info.CanWrite)
            {
                var binding = new Binding("Value")
                {
                    Mode = BindingMode.TwoWay,
                    Source = info,
                    ValidatesOnExceptions = true,
                    ValidatesOnDataErrors = true, 
                    Converter = new ColorToBrushTypeConverter()
                };
                BindingOperations.SetBinding(brushSelector, ColorPickerSelector.SelectedColorProperty, binding);
            }
            else
            {
                var binding = new Binding("Value")
                {
                    Mode = BindingMode.OneWay,
                    Source = info,
                    ValidatesOnExceptions = true,
                    ValidatesOnDataErrors = true,
                    Converter = new ColorToBrushTypeConverter()
                };
                BindingOperations.SetBinding(brushSelector, ColorPickerSelector.SelectedColorProperty, binding);
            }
 
        }        
 
        public object Create(System.Reflection.PropertyInfo PropertyInfo)
        {
            brushSelector = new ColorPickerSelector();
            return brushSelector;
        }        
 
        public void Detach(PropertyViewItem property)
        {            
        }
 
        #endregion
    }
 
    public class ColorToBrushTypeConverter : IValueConverter
    {
        #region IValueConverter Members
 
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if (value != null && value is SolidColorBrush)
            {
                return (value as SolidColorBrush).Color;
            }
            return value;
        }
 
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if (value != null)
            {
                return new SolidColorBrush((Color)value);
            }
            return value;
        }
 
        #endregion
    }
 
In ColorPickerSelector class, I have used a colorpickerpalette to select the color.
When I dispose the control, I notice that the ColorPickerSelector and  ColorToBrushTypeConverter object is retained in the memory.
I’m facing some memory leak issues due to this. I face this issue with other custom editors as well.
 I would like to know if the object is retained in the memory, if so how do I release the object.
