    How to handle Node.GetProperty("name").value when there is no value

    Hey guys I have an umbraco razor view that gets and displays an image, if there is no image i.e the umbraco user has not uploaded one, I don't want to page to crash, I want ignore that fact and load the rest of the page.

    At the moment I am doing this with a try catch block, but I know there must be a much better way to do this.

    @inherits

    Umbraco.Web.Mvc.UmbracoTemplatePage

    @{

    Layout = "umbLayout.cshtml";

bool hasMainImage = true;

try
{
    var currentPageNode = uQuery.GetCurrentNode();
    var mediaItemId = currentPageNode.GetProperty("mainImage").Value;
}
catch (Exception ex )
{

    hasMainImage = false;
}

    } With out the try block it will crash on currentPageNode.GetProperty("mainImage").Value;

    Hi Ayo,

    You could use the following to see if the property has value first:

    if (currentPageNode.HasProperty("mainImage") && currentPageNode.GetProperty("mainImage").Value != null)
{
    var mediaItemId = currentPageNode.GetProperty("mainImage").Value;
}

    Thanks, Dan.

    Thanks dan! Thats the kind of thing I was looking for having try catch is just unnecessary.

    Dan.... Its actually still crashing ................. Object reference not set to an instance of an object. it does not like currentPageNode.GetProperty("mainImage").Value when it has no value....
