How do I open a separate DetailView from a nested ListView with MasterDetailMode set to ListViewAndDetailView?

Hi Jascha,

To open the selected object's DetailView in a separate window in this scenario, override the XafApplication.ShowDetailViewFrom method in the WinApplication.cs file and return True for the required View. For example:

C#
namespace MainDemo.Win {  
    public partial class MainDemoWinApplication : WinApplication {  
        public override bool ShowDetailViewFrom(Frame sourceFrame) {  
            if (sourceFrame != null && sourceFrame.View is ListView) {  
                if (sourceFrame.View.Id == "Master_Details_ListView") {  
                    return true;  
                }  
            }  
            return base.ShowDetailViewFrom(sourceFrame);  
        }  

If you prefer to do this in a controller, use the following code:

C#
using System;  
using DevExpress.ExpressApp;  

public class EnableOpenDetailViewFromNestedListViewInDualModeViewController : DevExpress.ExpressApp.SystemModule.ListViewProcessCurrentObjectController {  
    protected override void ProcessCurrentObject(SimpleActionExecuteEventArgs e) {  
        if (View.Id == "Contact_Tasks_ListView") {  
            ShowObject(((ListView)View).CurrentObject, e.ShowViewParameters, Application, Frame, View);  
        } else {  
            base.ProcessCurrentObject(e);  
        }  
    }  
}  

Does this solution meet your needs?
