Is there a XAML equivalent to nameof?

For some reason my designer isn't working well with G.Sharada's solution, though it works great in runtime.

I went a slightly different route:

public class NameOfExtension : MarkupExtension
{
    private readonly PropertyPath _propertyPath;

    public NameOfExtension(Binding binding)
    {
        _propertyPath = binding.Path;
    }

    public override object ProvideValue(IServiceProvider serviceProvider)
    {
        var indexOfLastVariableName = _propertyPath.Path.LastIndexOf('.');
        return _propertyPath.Path.Substring(indexOfLastVariableName + 1);
    }
}

This way I can do:

<TextBlock Text="{local:NameOf {Binding Property1.Property2}}" />

This is not a replacement obviously since we may not have an instantiated object to bind to. I suppose I could have 2 constructors, one which takes a binding, and the other a Member string.

You can create a custom markup extension.

For example:

[ContentProperty(nameof(Member))]
public class NameOfExtension : MarkupExtension
{
    public Type Type { get; set; }
    public string Member { get; set; }

    public override object ProvideValue(IServiceProvider serviceProvider)
    {
        if (serviceProvider == null)
            throw new ArgumentNullException(nameof(serviceProvider));

        if (Type == null || string.IsNullOrEmpty(Member) || Member.Contains("."))
            throw new ArgumentException("Syntax for x:NameOf is Type={x:Type [className]} Member=[propertyName]");

        var pinfo = Type.GetRuntimeProperties().FirstOrDefault(pi => pi.Name == Member);
        var finfo = Type.GetRuntimeFields().FirstOrDefault(fi => fi.Name == Member);
        if (pinfo == null && finfo == null)
            throw new ArgumentException($"No property or field found for {Member} in {Type}");

        return Member;
    }
}
