What happens in case views are used

Can you show how the Textblock would look like?

Hi,

your TemplateColumn's ItemTemplate should look something like this:

<ig:TemplateColumn.ItemTemplate>
    <DataTemplate>
        <TextBlock Text="{Binding Path=YID,
                        Converter={StaticResource yourConverter},
                        ConverterParameter={StaticResource ViewYData}}" />
    </DataTemplate>
</ig:TemplateColumn.ItemTemplate>

and the value converter should like something like: 

public class LookupValueConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        var viewY = parameter as Dictionary<int, string>;

        return viewY[(int)value];
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
       //You don't need to ConvertBack since TextBlock is not an editor control
    }
}

Hello,

I have checked the sample you provided. I was not able to debug it and to make sure everything works. However I got the general idea. Here are few pointers:

You need to provide the DetailsTable1(or DetailsView1 - don't know are they different) - basically you need to provide  ConverterParameter the table that is mapping Id to TextDescription. Your TextBlock code should look something like this:

<TextBlock Text="{Binding Path=detailid1,
    Converter={StaticResource LookupValueConverter},
    ConverterParameter={Binding ElementName=LayoutRoot, Path=DataContext.DetailsView1}}" />

After that in the Converter you look up the parameter(you should know and cast to the type it is). The Convert method should look :

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)  
{
    var viewY = parameter as EntitySet<DetailsView1>;

    return viewY.FirstOrDefault(row => row.Id == (int)value).Description;
}

HTH,

What does the ElementName signify

Also I dont get intellisence for FirstOrDefault

Yes I have added the reference correctly

For somereason when i run the application I get error Provide value on 'System.Windows.Data.Binding' and this is on same line where i give the Converter
