How to set size of popup window when ShowViewInPopupWindow() method is used

Hello,

To accomplish this task, handle the XafApplication.CustomizeTemplate event as follows:

C#
using DevExpress.ExpressApp;  
using dxT695689.Module.BusinessObjects;  
using DevExpress.ExpressApp.Win.SystemModule;  
using DevExpress.ExpressApp.SystemModule;  
using DevExpress.ExpressApp.Templates;  
using DevExpress.ExpressApp.Win;  
using System.Windows.Forms;  
 namespace dxT695689.Module.Win.Controllers {  
    public class CustomWinShowStartupNavigationItemController : WinShowStartupNavigationItemController {  
        protected override void ShowStartupNavigationItem(ShowNavigationItemController controller) {  
            base.ShowStartupNavigationItem(controller);  
            ((WinWindow)Application.MainWindow).Form.BeginInvoke(new MethodInvoker(() => {  
                IObjectSpace os = Application.CreateObjectSpace(typeof(Contact));  
                object theObjectToBeShown = os.FindObject<Contact>(null);  
                DetailView dv = Application.CreateDetailView(os, theObjectToBeShown, true);  
                dv.ViewEditMode = DevExpress.ExpressApp.Editors.ViewEditMode.Edit;  
                Application.CustomizeTemplate += Application_CustomizeTemplate;  
                Application.ShowViewStrategy.ShowViewInPopupWindow(dv);  
                Application.CustomizeTemplate -= Application_CustomizeTemplate;  
            }));  
        }  
        private void Application_CustomizeTemplate(object sender, CustomizeTemplateEventArgs e) {  
            ((XafApplication)sender).CustomizeTemplate -= Application_CustomizeTemplate;  
            IWindowTemplate formTemplate = e.Template as IWindowTemplate;  
            if(formTemplate != null && formTemplate is System.Windows.Forms.Form) {  
                if(formTemplate is ISupportStoreSettings) {  
                    ((ISupportStoreSettings)formTemplate).SettingsReloaded += (sender1, e1) => {  
                        ((System.Windows.Forms.Form)sender1).WindowState = System.Windows.Forms.FormWindowState.Maximized;  
                    };  
                } else {  
                    ((System.Windows.Forms.Form)formTemplate).WindowState = System.Windows.Forms.FormWindowState.Maximized;  
                }  
            }  
        }  
    }  
}  

Let me know in case of any further difficulties.

Thanks,
Andrey
