Sometimes your want to show some kind of modal dialog instantly after the user logged into the XAF web application. An easy way to do so is to inherit a class from the “WebShowStartupNavigationItemController” and override the “ShowStartupNavigationItem” method therein:
public class CustomWebShowStartupNavigationItemController : WebShowStartupNavigationItemController
{
protected override void ShowStartupNavigationItem()
{
base.ShowStartupNavigationItem();
var currentUser = SecuritySystem.CurrentUser as Users;
if (!currentUser.ShowTheMessageBox)
{
IObjectSpace os = Application.CreateObjectSpace();
object theObjectToBeShown = os.FindObject<Users>(null);
DetailView dv = Application.CreateDetailView(os, theObjectToBeShown, true);
dv.ViewEditMode = DevExpress.ExpressApp.Editors.ViewEditMode.Edit;
DialogController dc = Application.CreateController<DialogController>();
Window popupWindow = Application.CreatePopupWindow(TemplateContext.PopupWindow, null, dc);
popupWindow.SetView(dv);
((WebApplication)Application).PopupWindowManager.ShowPopup((WebWindow)popupWindow, (WebWindow)Window);
// ...
Combined with the technique described in the Using non persistent objects to display modal dialogs topic any content can be shown in those modal dialogs.
