【问题描述】：
我有一个与集合绑定的 dataGrid。对于两列（A 和 B），数据为 1 或 0。 相反，我想在组合框列中显示是或否，当然如果选择“是”，则保存 1，“否”为 0。
我该怎么做？
查看
<DataGrid x:Name="dataGrid" ItemsSource="{Binding Collection}" AutoGenerateColumns="False"
SelectedItem="{Binding Selected, Mode=TwoWay}">
<DataGrid.Columns>
<DataGridTextColumn Header="id" Binding="{Binding idproduct, UpdateSourceTrigger=PropertyChanged}" Visibility="Hidden"/>
<DataGridTextColumn Header="Ref Supplier" Binding="{Binding refsup, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Header="Description" Binding="{Binding description, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridComboBoxColumn Header="Unit"
ItemsSource="{Binding Collection, Source={StaticResource unit}}"
DisplayMemberPath="unit1"
SelectedValueBinding="{Binding unit}"
SelectedValuePath="idunit"/>
<DataGridTextColumn Header="Price/MOQ" Binding="{Binding priceMOQ, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Header="A" Binding="{Binding A, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Header="B" Binding="{Binding B, UpdateSourceTrigger=PropertyChanged}"/>
</DataGrid.Columns>
</DataGrid>
视图模型
public class ProductViewModel : ViewModelBase
{
public Context ctx = new Context();
private ObservableCollection<product> collection;
public ObservableCollection<product> Collection
{
get
{
if (collection == null)
{
Get();
}
return collection;
}
set
{
collection = value;
OnPropertyChanged("Collection");
}
}
#region "Command"
}
型号
public partial class product
{
public int idproduct { get; set; }
public string refsup { get; set; }
public string description { get; set; }
public Nullable<int> unit { get; set; }
public sbyte larot { get; set; }
public sbyte lasand { get; set; }
public virtual foodSupplier foodSupplier { get; set; }
public virtual unit unit1 { get; set; }
}
更新
这两种方法我都试过了，还是不行。

{
byte inValue = System.Convert.ToByte(value);
string outValue = (inValue == 1) ? "Yes" : "No";
return outValue;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
switch (value.ToString().Trim().ToLower())
{
case "yes":
return 1;
case "no":
return 0;
default:
return 0;
}
}
}
