        var references = new[]
        {
            MetadataReference.CreateFromFile(typeof (object).Assembly.Location),
            MetadataReference.CreateFromFile(typeof (TValidationResult).Assembly.Location),
            MetadataReference.CreateFromFile(typeof (TModel).Assembly.Location)
        };
        var dynamicCompiler = new DynamicCompiler();

public class FormValidationResult

    public WebFormValidationResult()
    {

    }

    public override string ToString()
    {
        return $"HasError: {HasError}, Message: {Message}, FieldName: {FieldName}";
    }
}

Use like so:

var validationScript = "return new FormValidationResult(model.FirstName == \"John\");"
var model = new FormModel { FirstName = "Lars", LastName = "Doe", Age = 61 };
var validationHelper = new FormValidationHelper();
var result = validationHelper.DoDynamicValidation(model, validationScript);

        var attribute = memberInfos[0].GetCustomAttributes(typeof (T), false);

        var attributes = attribute.Cast().ToList();
        
        return attributes.SingleOrDefault();
    }

    public static string Description(this Enum enumeration)
    {
        var attribute = GetAttribute(enumeration);
        if (attribute == null)
            return "";

        return attribute.Description;
    }
}

public enum GroundType
{
    [Description("Jord")]
    Soil = 1,
    [Description("Gräs")]
    Grass = 2
}

public class DescriptionAttribute : Attribute
{
    private readonly string _descr;

    public DescriptionAttribute(string descr) { _descr = descr; }

    public string Description
    {
        get { return _descr; }
    }

    public override string ToString() { return Description; }
}

Use like so:

var groundType = GroundType.Soil;
var desc = groundType.Description();

JavaScript Scrapbook addition

A repeater with a nested GridView. All GridViews have their own UpdateProgress controls.
This hides all UpdateProgress divs but the one for the specific GridView that triggered the AJAX call.

$('.applicationRowAction').live("click", function () {
            var tableHeight = $(this).closest('table').height();
            var panelMarginTop = (tableHeight / 2)
            var appId = $(this).parent().parent().find('.divRowAppWrapperId').attr("id").substring(4);
            $('.updateProgress').css('margin-top', panelMarginTop + 'px');
            $('.updateProgress').each(function () {
                var divId = $(this).attr("id").substring(17)
