如何将 PopUpWindow 设置为与应用程序在同一台显示器上？ (xaf)

Question

用户经常在显示器之间移动我的 XAF Winforms 应用程序。但是 PopUpWindowShowAction 调用的对话框仍保留在旧监视器上

这个问题可以在 Dev Express 的主要演示中重复出现（尽管要在那里调试它我认为我需要进入 API 代码）。

运行主演示并将应用程序 window 移动到第二台显示器。
Select 用户，右键单击用户并 select 打印预览。

打印预览将出现在第一台显示器上。

在我的类似情况下，我的控制器是

public partial class JobHeadFilterController : ViewController, IClassicController
{
    public JobHeadFilterController()
    {
        InitializeComponent();
        TargetViewNesting = Nesting.Root;
    }

    protected override void OnActivated()
    {
        base.OnActivated();
        popupWindowShowFilterAction.QuickAccess = true;
    }

    private void popupWindowShowFilterAction_CustomizePopupWindowParams(object sender,
        CustomizePopupWindowParamsEventArgs e)
    {
        var holder = new JobHeadFilterHolder();
        var npProvider = new NonPersistentObjectSpaceProvider(XafTypesInfo.Instance, null);
        var os = (NonPersistentObjectSpace)npProvider.CreateObjectSpace();
        var view = Application.CreateDetailView(os, holder);
        e.View = view;
    }

我已尝试浏览 CustomizePopupWindowParamsEventArgs 的属性，但看不到要设置的内容。

我可以使用

获取主窗体

 var mainform = Application.MainWindow.Template as Form;

我想我需要在里面做类似下面的事情 popupWindowShowFilterAction_CustomizePopupWindowParams

            var template = e.Application.MainWindow.Template;
            var window = new Window(Application, );  // having trouble figuring out the parameters
            e.DialogController.SetWindow(window);

正在学习the docs

[更新]

我试过了

var window = e.Application.MainWindow; e.DialogController.SetWindow(window);

但出现错误

The 'DevExpress.ExpressApp.SystemModule.DialogController' controller is active.

我尝试制作自己的继承自 Dev DevExpress.ExpressApp.SystemModule.DialogController 的对话框控制器，但遇到了同样的错误。

using System;
using System.Windows.Forms;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Templates;
using DevExpress.ExpressApp.Win.Templates;
namespace MyNameSpace;
 
public partial class CustomizeFormsWindowController : WindowController
{
    public CustomizeFormsWindowController()
    {
        InitializeComponent();
        TargetWindowType = WindowType.Child;
    }

    protected override void OnActivated()
    {
        base.OnActivated();
        Window.TemplateChanged += WindowsTemplateChanged;
    }

    private void WindowsTemplateChanged(object sender, EventArgs e)
    {
        if (Window.Template is Form &&
            Window.Template is ISupportStoreSettings)
            ((ISupportStoreSettings)Window.Template).SettingsReloaded +=
                OnFormReadyForCustomizations;
    }

    private void OnFormReadyForCustomizations(object sender, EventArgs e)
    {
        if (sender is not PopupForm popupForm) return;
        var mainForm = Application.MainWindow.Template as Form;
        var X = mainForm.Location.X + (mainForm.Width - popupForm.Width) / 2;
        var Y = mainForm.Location.Y + (mainForm.Height - popupForm.Height) / 2;
        popupForm.SetDesktopLocation(X, Y);
    }

    protected override void OnDeactivated()
    {
        Window.TemplateChanged -= WindowsTemplateChanged;
        base.OnDeactivated();
    }
}
