使用 sql 集合中的单选按钮组绑定值

Question

Good morning,

So this is basically like a ticket system, you fill in a ticket and then someone with higher permissions will be able to go in and open that ticket. When they open that ticket I got everything else binding besides the RadioButtonGroup . All the data is fetched from SQL and stored into a collection from a class using SqlReader as you see below the textboxes are getting their binded value

example of radio button groups

To quickly explain what I am trying to do. I would like to have this group of radio buttons that when I select a RadioButton and press save I can save the value into the SQL. Then I would like to be able to bind that value and have it binded when someone pulls up that ticket like the textboxes

XAML

<WrapPanel Margin="0,10,0,0" VerticalAlignment="Top" Height="20">
                    <RadioButton Content="Domestic"
                    GroupName="RadioButtonGroup"
                    IsChecked="{Binding RadioButtonSource, Converter={StaticResource EnumBooleanConverter}, ConverterParameter={x:Static model:RadioButtonSource.Domestic}}" />
                    <RadioButton Content="Japan"
                    GroupName="RadioButtonGroup"
                    IsChecked="{Binding RadioButtonSource, Converter={StaticResource EnumBooleanConverter}, ConverterParameter={x:Static model:RadioButtonSource.Japan}}" />
                    <RadioButton Content="House"
                    GroupName="RadioButtonGroup"
                    IsChecked="{Binding RadioButtonSource, Converter={StaticResource EnumBooleanConverter}, ConverterParameter={x:Static model:RadioButtonSource.House}}" />
                </WrapPanel>

Class

Source = reader.GetInt32("source");

public int _Source;
        public int Source
        {
            get { return _Source; }
            set { _Source = value; RaisePropertyChanged("source"); }
        }

Converter

public class EnumBooleanConverter : MarkupConverter
    {
        protected override object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return value?.Equals(parameter);
        }

        protected override object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return (bool)value == true ? parameter : Binding.DoNothing;
        }
    }

Then I also made this enum for it in it's own class

public enum RadioButtonSource
    {
        Domestic,
        Japan,
        House
    }

then the SQL to insert a new ticket

cmd.Parameters.AddWithValue("@entrydate", Date);
            cmd.Parameters.AddWithValue("@source", Source);
            cmd.Parameters.AddWithValue("@prodcell", Prodcell);
            cmd.Parameters.AddWithValue("@workcenter", Workcenter);
            cmd.Parameters.AddWithValue("@supplier", Supplier);
            cmd.Parameters.AddWithValue("@createdby", Createdby);
            cmd.Parameters.AddWithValue("@department", Dept);
            cmd.Parameters.AddWithValue("@deptdesc", deptdesc);
            cmd.Parameters.AddWithValue("@reviewedby", Reviewedby);
            cmd.Parameters.AddWithValue("@shift", Shift);
            cmd.Parameters.AddWithValue("@parts", SerializedParts);
            cmd.Parameters.AddWithValue("@problem", problemRB);
            cmd.Parameters.AddWithValue("@problemdesc", Problemdesc);
            cmd.Parameters.AddWithValue("@supplotnum", Supplierlotnum);

everything works but Source
