How to display the currently logged user name in the header bar near the Log Off Action on the Web

Here is another recent support thread update about personalizing your Web app:

To accomplish your task, consider one of the following solutions depending on your business requirements:

1. Default web template modification
Create a custom Default content template and add a new table cell with the following code to the markup (between cells containing the logo and header menu):

[ASPx]
                    ...
                    <td>
                        <img src="Images/Logo.png" />
                    </td>
                    <td class="width100"></td>
                    <td><%= DevExpress.ExpressApp.SecuritySystem.CurrentUserName %></td>
                    <td>
                        <div id="xafHeaderMenu" class="xafHeaderMenu" style="float: right;">
                        ...
                    </td>
                    ...

2. Inherit from the standard HeaderMenuController class
Override its GetActionContainerCaption method (and optionally the GetActionContainerImageUrl method) as shown in our XCRM demo ("C:\Users\Public\Documents\DevExpress Demos 1X.X\Components\eXpressApp Framework\XCRM\CS\XCRM.Module.Web\CustomHeaderMenuController.cs").

3. Customizing the "My Details" Action caption directlyYou can customize the standard MyDetailsController class in the following manner (optionally, customize the corresponding navigation item):

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.ExpressApp.Security;
using DevExpress.ExpressApp.SystemModule;

namespace MainDemo.Module {
    public class WindowController1 : WindowController {
        public WindowController1() {
            TargetWindowType = WindowType.Main;
        }
        protected override void OnActivated() {
            base.OnActivated();
            string ActionItemId = "MyDetails";
            Frame.GetController<MyDetailsController>().Actions[ActionItemId].Caption = SecuritySystem.CurrentUserName;
            //Optionally, customize the corresponding navigation item.
            Frame.GetController<ShowNavigationItemController>().ShowNavigationItemAction.Items.Find(
                ActionItemId, ChoiceActionItemFindType.Recursive, ChoiceActionItemFindTarget.Leaf
            ).Caption = SecuritySystem.CurrentUserName;
        }
    }
}
