ModelMetaData, Custom Class Attributes and an indescribable question

Question

What I want to do seems so simple.

In my index.cshtml I want to display the WizardStepAttribute Value

So, a user will see at the top of each page,

Answer 1

In our case we just needed an attribute that implements the IMetadataAware interface:

In your case, this could be:

public class WizardStepAttribute : Attribute, IMetadataAware
{
    public string Name;

    public void OnMetadataCreated(ModelMetadata metadata)
    {
        if (!metadata.AdditionalValues.ContainsKey("WizardStep"))
        {
            metadata.AdditionalValues.Add("WizardStep", Name);
        }
    }
}
