I've seen that is possible editing a NavigationViewItem control template by accessing the item "LayoutRoot" in a Grid, so I would like to know which elements build the navigationview in order to create a control template with a custom Style.

I am not able to design below layout in qt -designer
So under main window , we have one horizontal Layout that have two vertical Layout and each vertical Layout have.
one horizontal Layout that contains combo box and push button
And another Listview widget
Since you didn't include any information about what steps you followed in trying to create this layout and what the final result was, it's impossible to tell where things go wrong. However, to create the layout as described in the post, you could do the following.
Step 1: Add widgets to form
In a new form in Qt Designer, roughly place the widgets where you want them to be in the final layout.
Step 2: Add widgets to layouts
Add widgets to layouts starting with the deepest nested widgets. In this case that would be the comboboxes and push buttons. To add a push-button and combobox to a layout, select both push-button and combobox, either in the layout itself or in the object inspector, right-click on the selection and select lay out > lay out horizontally in the context menu.
Repeat these steps for the other widgets and layouts. When adding the horizontal layout and the list view to a vertical layout, make sure you select the layout and not one of the widgets in the layout:
Step 3: Set layout of main window
To set the layout of the main window, right-click either anywhere in the main area of the form outside of any child widget or on the MainWindow node in the object inspector and select layout > lay out horizontally. This should result in something like this
And the object tree in the object inspector will look something like this
I would like to create a simple wizard based on a TabControl in Avalonia UI with four pages. Each page with a few controls. Instead of the TabItem headers I would like to create my own buttons and hide the default TabItem headers.
There are plenty of solutions for WPF, mostly involving ItemsContainerStyle and the Visibility property, both of which don't seem to be accessible in the Avalonia TabControle.
Is there any way to hide the headers?
Or is there a better way to implement a wizard?
You probably need to use the Carousel class directly. It's used by the TabControl internally for presenting the current item.
See example usage here:
https://github.com/AvaloniaUI/Avalonia/blob/master/samples/ControlCatalog/Pages/CarouselPage.xaml - markup
https://github.com/AvaloniaUI/Avalonia/blob/master/samples/ControlCatalog/Pages/CarouselPage.xaml.cs - codebehind
When I use a Button control in DataTemplate for ListView (UWP app), Drag-and-Drop of ListView items doesn't work. If I use containers like StackPanel, RelativePanel or Grid, instead of Button control, everything works fine. I would prefer the Button control as a container, because I like its mouse Hover effect on ListView items. I can do something similar for StackPanel, etc, with a custom hover effect by using a combination of Style and Behavior programming but trying to avoid this route (too involved).
Can I do something to the Button control so that it gives me the hover and also responds to the Drag-and-Drop event when part of a ListView DataTemplate?
I am also curious what specifically makes the Button suppress the Drag-and-Drop of ListView items.
The Button is capturing the pointer which cause the pointer click event not be bubble up to the ListViewItem which cause the Drag&Drop to start.
You can take a look at ReleasePointerCapture method which will release the pointer capture allowing other item to capture it.
You will need to create a new class which extends the default Button class and override for example the OnPointerPressed method to choose the logic between the drag&drop and the click on the button.
Using a Xamarin Forms ListView with a custom ViewCell, is it possible to have a list item expand based on an event? Please ignore the orange lines, but reference the below picture...
Regular cell not expanded
User has tapped the triple dots causing the ViewCell to expand to show additional content
Is this possible? What is the technique to make that work?
You can have containers or elements inside your viewcell whose Visibility can be controlled based on the click. You will have to re render the elements once its expanded or collapsed for the viewcell to resize. Or else you will have the Viewcell being the size it was initially rendered, but the contents inside it overflowing.

Am trying to add a none extjs element to a toolbar menu items, let's say for example I want to add a jquery ui element to the extjs menu items.
Is this possible or doable?
Thanks
You can wrap the jQuery component as a ExtJS Component and use it inside the toolbar.
This basically involves extending Ext.Component and overriding the render function.
