String[] column needs to be displayed on Infragisticsgrid


I have a column by name Synonyms in my data model which is string[] type.

 public string[] Synonyms { get; set; }

Want to create a column name for Synonyms in the infragisctics grid.

 <converter:StringArrayToStringConverter x:Key="StringArrayToStringConverter"></converter:StringArrayToStringConverter>

<igDP:Field Name="Synonyms" AllowEdit="True" Label="{x:Static prop:Resources.MaintDraw_RecordGrid_Synonyms}" Visibility="Visible" Converter="{StaticResource StringArrayToStringConverter}" >
<igDP:FieldSettings EditAsType="system:String"/>

public class StringArrayToStringConverter : IValueConverter
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
string convertString = string.Empty;
if(value is string[] cast)
foreach(var str in cast)
convertString = string.Concat(convertString, ", ", str);
return convertString;

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
throw new NotImplementedException();

Unfortunately, i am not able to display that column? 

Can you quickly provide me the solution?
