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;
```
