Override property with IgnoreAttribute

In EPiServer 7.0 I can do:

public abstract class SitePageData : PageData
{
    [Ignore]
    public virtual string Heading
    {
        get { return this.Name; }
        set { throw new NotImplementedException(); }
    }
}

public class InformationPage : SitePageData
{
    [CultureSpecific]
    [Display(GroupName = SystemTabNames.Content, Order = 10)]
    public override string Heading
    {
        get
        {
            string heading = this.GetPropertyValue(content => content.Heading);

            return !string.IsNullOrEmpty(heading) ? heading : this.Name;
        }
        set { this.SetPropertyValue(content => content.Heading, value);
       }
    }
}

But I can not do this in 7.5. It looks like the IgnoreAttribute cant be overridden. If I look at the InformationPage in Admin-mode the property "Heading" is missing. Should I be able to do like this? Or how should I solve it?

Haven't used myself. What about Scaffold(false) ?

Try using

public new virtual string Heading {...}

I would suggest that you take another approach on your class inheritance..

And if you need to have fallback data on values it's mostly a better approach to let the rendering do this instead of adding this to the model/pagetype.

ScaffoldColumn(false) doesn't stop EPiServer serialize the property I think

Hi, and thanks all

Sorry for not answering earlier, been busy busy busy doing nothing at all... ;-)

First I solved it like this (as Per also have suggested)

public abstract class SitePageData : PageData
{
    public virtual string Heading
    {
        get
        {
            string heading = this.GetPropertyValue(content => content.Heading);
 
            return !string.IsNullOrEmpty(heading) ? heading : this.Name;
        }
    }
}
 
public class InformationPage : SitePageData
{
    [CultureSpecific]
    [Display(GroupName = SystemTabNames.Content, Order = 10)]
    public new virtual string Heading
    {
	get { return base.NavigationItemName; }
	set { this.SetPropertyValue(content => content.NavigationItemName, value); }
    }
}

But I want to avoid overriding with "new". So I will try "ScaffoldColumn", didnt know about that attribute. I will also consideer what Alf says, I agree you have a point there.
