I'd give this a read: https://learn.microsoft.com/en-us/dotnet/desktop/wpf/controls/control-authoring-overview?view=netframeworkdesktop-4.8

I'm making an assumption, but based on your class names your edit 'form' is actually a window. You likely want to make a UserControlUserControl that you can include in your main window's xaml.

Control Authoring Overview - WPF .NET Framework

The extensibility of Windows Presentation Foundation controls minimizes the need to create custom controls. Learn how to create a new control, if necessary.

I read it but I did not see the point where to start - yes I have a user control in my main window - a button e.g

private void btnEditor_Click(object sender, RoutedEventArgs e)
{

EditWin EditForm = new EditWin();
EditForm.Show();

}

and it opens a another form (window) now I would like to see the same in the main window

Kkatonaut I read it but I did not see the point where to start - yes I have a user control...

A ButtonButton and a UserControlUserControl are two different things. UserControlUserControl is a base you can inherit from you make your own custom controls. I'd give the link above a closer read because it feels as though you missed the point.

For example, you could take all of the xaml from your EditWinEditWin and use it to create a new user control named EditFormEditForm. This new control could then be used wherever you want by doing something like this in your xaml:

<uc:EditForm PropertiesAndStuff={...} />

<uc:EditForm PropertiesAndStuff={...} />

What exactly do you mean by 'see the same in the main window'?

I have a main window with button and I click on it - but the table with data opens not in a second window - it opens in the same window - when I click back it should come to the first main xaml (window) again - all in the same window

how to achieve this

Not super familiar with WPF (usually mess with Avalonia), but assuming you're following MVVM patterns you'd probably want to have some state on the main windows view model to track which view is being displayed.

From there you have multiple options. You could explicitly tie the VisibilityVisibility property of your views to the state of your main window's view model.
Another option would be using a DataTriggerDataTrigger to modify the style of your components (which also includes visibility).
