public static string DatePickerFor<TModel, TProperty>(
    this HtmlHelper<TModel> htmlHelper,
    Expression<Func<TModel, TProperty>> expression,
    string imageUrl)
{
    if (expression == null)
    {
        throw new ArgumentNullException("expression");
    }

    var expressionText = ExpressionHelper.GetExpressionText(expression);
    return DatePicker(htmlHelper, expressionText, imageUrl, htmlHelper.ViewData.Eval(expressionText));
}
