Remarks

SfDataGrid allows you to group a column based on custom logic when the standard grouping techniques do not meet the requirements. When the user wants to apply grouping to the column based on his custom logic, he needs to the write the converter class implementing the IValueConverter and assign it to this property.

Examples
dataGrid.GroupColumnDescriptions.Add (new GroupColumnDescription () {
ColumnName = "CustomerID",
Converter = new GroupConverter()
});

//GroupConverter.cs
public class GroupConverter : IValueConverter
{

}
