Guys, I am using the awesome datatype grid in ucomponents. I have some text fields and media picker fields. The media picker fields are not mandatory and therefore will not always have a value in my code i have the following:

var answers=new List<Answer>();

        var lib = new umbraco.MacroEngines.Library.RazorLibraryCore(questionNode);

        var answerXml = lib.ToDynamicXml(questionNode.GetProperty<string>(DocumentType.Questions.Question.Answers));

        foreach (var answer in answerXml)
        {
            var answerPoco = new Answer
            {
                QuestionId = questionNode.Id,
                Text = answer.answer.InnerText,
                Weight = int.Parse(answer.weight.InnerText),
                PercentageAnswered = answer.percentageAnswered.InnerText
            };

           //todo cyan / pink
            //DIES HERE HOW DO I TEST IT EXISTS
            if (answer.answerCyan != null && !string.IsNullOrEmpty(answer.answerCyan.ToString()))
            {
                answerPoco.CyanImg = answer.answerCyan.InnerText;
            }

            if (answer.answerPink != null && !string.IsNullOrEmpty(answer.answerPink.ToString()))
            {
                answerPoco.PinkImg = answer.answerPink.InnerText;
            }

            answers.Add(answerPoco);
        }

I need to test that the property exists before trying to reference it. So answercyan and answerping are media pickers in the datatype grid datatype and will not always have a value.

Regards
