WinUi3 Window Help

[jarno9981]

Using WinUiEx 2.2.0

i have uwp project

using this code

var coreTitleBar = CoreApplication.GetCurrentView().TitleBar;
coreTitleBar.ExtendViewIntoTitleBar = true;

coreTitleBar.LayoutMetricsChanged += CoreTitleBar_LayoutMetricsChanged;

But When I Use it in WinUi3 With WinUiEx then it gives error .GetCurrentView().TitleBar; no element
found using this Code For titlebar

App.MainWindow.ExtendsContentIntoTitleBar = true;
App.MainWindow.SetTitleBar(CustomDragRegion);
App.MainWindow.Activated += MainWindow_Activated;
App.MainWindow.Title = "FireBrowser WinUi3";

but i cant find LayoutMetricsChanged i want to use the method the use

`` if (FlowDirection == FlowDirection.LeftToRight)
{
CustomDragRegion.MinWidth = sender.SystemOverlayRightInset;
}
else
{
CustomDragRegion.MinWidth = sender.SystemOverlayLeftInset;

}

// Ensure that the height of the custom regions are the same as the titlebar.
CustomDragRegion.Height =  sender.Height;`

without CoreTitleBar_LayoutMetricsChanged i cant use flowdirection

@jarno9981 I'm a bit confused about your question. I don't really see any WinUIEx APIs being used above.

I want to get the current titlebar so i can use overflow but when using WinUiEx it wont work but normal Window will work

Thank you. That wasn't clear that the difference is WinUIEx Window vs WinUI3 Window. You were only comparing to your UWP version above.
Don't set the Content to null. That'll mess with WinUIEx's custom handling of titlebar.

Btw, I'd actually recommend that you don't use WindowEx, but instead use the regular Window and use WinUIEx's WindowManager and extension methods to get at all the Window enhancements.

But WindowEx has better titlebar costimaztion and window handling then normal window that why i am using WindowEx

[jarno9981]

Set the content in your xaml
