Hi Nguyen,

Based on provided information the reported problem occurs due to mismatch in underline DataType of GridComboBoxColumn. Your under line DataType is Enum but Display Name is string type. In this case, the reported problem occurs in GridComboBoxColumn.

Your requirement can be achieved by using DisplayBinding property in GridColumn. Please refer the below code snippet,

XAML Code Snippet: 

<syncfusion:SfDataGrid  ItemsSource="{Binding Orders}" 

                                AutoGenerateColumnsForCustomType="True" 

                                AutoGenerateColumnsModeForCustomType="Child" 

                                ColumnSizer="SizeToHeader" 

                                AllowEditing="True" 

                                SelectionMode="Extended" 

                                AutoGeneratingColumn="OnAutoGeneratingColumn" 

                                AllowSorting="False" 

                                AllowFiltering="False" 

                                x:Name="sfDataGrid" >            

        </syncfusion:SfDataGrid> 

C# Code Snippet: 

private void OnAutoGeneratingColumn(object sender, AutoGeneratingColumnArgs e) 

{ 

            if (e.Column.MappingName == "Description") 

            { 

                ((e.Column as GridComboBoxColumn).DisplayBinding as Binding).Converter = new EnumDisplayNameConverter(); 

            } 

} 

C# Code Snippet of Converter: 

public class EnumDisplayNameConverter : IValueConverter 

    { 

        public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 

        { 

            var display = value.GetType()?.GetMember(value.ToString())?.First().GetCustomAttribute<DisplayAttribute>(); 

            return display.Name; 

        } 

 

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 

        { 

            throw new NotImplementedException(); 

        } 

    }
