Hello,
I create a RelatedMediaField to custum my "Edit Page" : (Administration->Advanced->ContentView->Controls->FrontEndPages->FrontEndPagesCreate)

Problem : How can I get this image url ?
node.GetValue<Telerik.Sitefinity.Libraries.Model.Image>("MyMediaField").Url;
=> Error : System.Exception: Wrong custom field 'MyMediaField' for type 'Telerik.Sitefinity.Pages.Model.PageNode'
Maybe DataFieldName attribute bad done ?
Please help.
Thanks !!

Hello,

Make sure you filter the page node by the current frontend root node id to ensure you are getting the correct root node. Also if you have not explicitly specified that only 1 image can be selected you have to specify the generic parameter as "List<Telerik.Sitefinity.Libraries.Model.Image>".

Try the following code:

var pageManager = PageManager.GetManager();

var pageNode = pageManager.GetPageNodes().Where(pn => pn.Title == "Schools" && pn.RootNodeId == SiteInitializer.CurrentFrontendRootNodeId).FirstOrDefault();

var images = pageNode.GetValue<List<IDataItem>>("MyMediaField").Cast<Telerik.Sitefinity.Libraries.Model.Image>();

var mediaUrl = images.FirstOrDefault().MediaUrl;
