    Getting Property value from the Homepage and displaying throughout in a partial view

    Afternoon all,

    I am completely new to Umbraco/MVC and I'm working on the following which I wounder if someone could give me a hand with? (using v7.13.2)

    Each page on my site has the ability to change the background image of the header on that page, but I would like to add: If no image has been selected on a page, go to the homepage and use the image from there.

    This is what I have so far:

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage


int imageId = Umbraco.AssignedContentItem.GetPropertyValue<int>("topBannerImage");
string topBannerImage = Umbraco.Media(imageId).Url;

if (string.IsNullOrWhiteSpace(topBannerImage))
{

    var homePageImage = Model.Content.Parent.GetPropertyValue<IPublishedContent>("topBannerImage").Url;
    topBannerImage = homePageImage;

}<header style="background-image:url('@topBannerImage')"></header>

    The above works for picking a image per page, but not by going to the root level and getting the value from there if the Media picker is empty.

    I have looked through forums/other sites and had no luck with this.

    Can anyone help?

    Hi David

    Use this code:

    int imageId = Umbraco.AssignedContentItem.GetPropertyValue<int>("topBannerImage");
string topBannerImage = imageId >0 ? Umbraco.Media(imageId).Url : string.Empty;

if (string.IsNullOrWhiteSpace(topBannerImage))
{

    var homePageImage = Model.Content.Site().GetPropertyValue<IPublishedContent>("topBannerImage").Url;

    topBannerImage = homePageImage;
}

    This method:

    Model.Content.Site().GetPropertyValue

    Always looks at the root node, so it's what you need.

    Thanks,

    Alex

    Thanks for this Alex. I have implemented my code as you have suggested, but the page is returning: "Object reference not set to an instance of an object.

    Here is what I have in my partial view: 

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage


int imageId = Umbraco.AssignedContentItem.GetPropertyValue<int>("topBannerImage");
string topBannerImage = imageId > 0 ? Umbraco.Media(imageId).Url : string.Empty;


if (string.IsNullOrWhiteSpace(topBannerImage))
{

    var homePageImage = Model.Content.Site().GetPropertyValue<IPublishedContent>("topBannerImage").Url;
    topBannerImage = homePageImage;

}

    Hi David,

    In which line exception?

    Can you change :

    string topBannerImage = imageId > 0 ? Umbraco.TypedMedia(imageId).Url : string.Empty;

    Umbraco.TypedMedia instead of Umbraco.Media

    Thanks,

    Alex

    Alex,

    This is the line in question it is complaining about:

    var homePageImage = Model.Content.Site().GetPropertyValue<IPublishedContent>("topBannerImage").Url;

    Hi David

    Please, check what do you have in the root node in "topBannerImage" property.

    There is should be a media item selected.

    Thanks,

    Alex

    To avoid this exception you can use this code:

        var homePageImage = Model.Content.Site().GetPropertyValue<IPublishedContent>("topBannerImage");
    if (homePageImage != null)
    {
        topBannerImage = homePageImage.Url;
    }

    Thanks for the help on this Alex. Earlier today I managed to get this working using the following: 

    var homePageImage = Umbraco.AssignedContentItem.Ancestor(1).GetPropertyValue<IPublishedContent>("topBannerImage").Url;
