WPF ShowDialog - change parent window's cursor

I have a little problem when opening a window by ShowDialog.
I have a main window which when the application is loading data from the data source, opens another small window as a dialog to show the loading progress.
When the small loading progress window opens up, the cursor of that window is set to a custom Busy cursor and I am trying to set the main window's cursor to be the same as in the small loading window, but no matter what I try, it doesn't work.
I know that when opening a window as a dialog with ShowDialog, the opening window's cursor is set to be the normal default cursor (when hovering over your dialog, you have your selected cursor, but when hovering over the main window while the dialog is open, the cursor is set to the default cursor [arrow]).
I am trying to make my app show the same custom Busy cursor when the loading dialog is open, while hovering over the dialog itself and over the window that has opened the dialog, while preventing the user from accessing the main window's content, preventing from minimizing the small loading window and preventing from letting the small loading window be under the main window.
Is there any way of doing so (as stated above) while using ShowDialog or something similar to ShowDialog?
Is there way of changing the default cursor of the ENTIRE application (for example a custom arrow cursor instead of the one windows has by default)?
Is there any way of opening a dialog, setting it's cursor to be a custom Busy cursor and by that setting that cursor to be present while hovering over any part of the application?
My codes:
private void Window_ContentRendered(object sender, EventArgs e)
{
Mouse.OverrideCursor = new Cursor(System.IO.Path.GetFullPath(System.IO.Path.Combine(strCurrentDir, #"..\..\")) + #"Cursors\busy.ani");
//this.Cursor = new Cursor(System.IO.Path.GetFullPath(System.IO.Path.Combine(strCurrentDir, #"..\..\")) + #"Cursors\busy.ani");
//Mouse.OverrideCursor = Cursors.Wait;
bwReload = new BackgroundWorker();
bwReload.WorkerReportsProgress = true;
bwReload.DoWork += (sender_bw, e_bw) =>
{
new Thread(() =>
{
Application.Current.Dispatcher.Invoke(() =>
{
ProgressBarWindow pbwLoadWindow = new ProgressBarWindow("Loading...", this);
pbwLoadWindow.ShowInTaskbar = false;
pbwLoadWindow.Owner = this;
pbwLoadWindow.Cursor = new Cursor(System.IO.Path.GetFullPath(System.IO.Path.Combine(strCurrentDir, #"..\..\")) + #"Cursors\busy.ani");
pbwLoadWindow.ShowDialog();
});
}).Start();
ReloadA();
ReloadB();
};
bwReload.RunWorkerCompleted += (sender_bw, e_bw) => btnViewDashboard_Click(this, null);
bwReload.RunWorkerAsync();
}
Thanks in advance.

SOLVED
It is simple.
All you need to do is go to the dialog window's xaml and fit the window like that, that it will cover the entire main window.
Code:
<Window x:Class="PlGui.ProgressBarWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:PlGui"
mc:Ignorable="d" Height="600" Width="1025"
ResizeMode="NoResize" WindowStartupLocation="CenterScreen"
WindowStyle="None" AllowsTransparency="True">
<Window.Background>
<SolidColorBrush Opacity="0.01" Color="White"/>
</Window.Background>
<Grid Height="100"
Width="350"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="#7f8c8d">
......
</Grid>
</Window>
The results:

Window Maximise only works after resizing manually first [duplicate]

I am trying to have the SizeToContent="WidthAndHeight" and WindowState = "Maximized" at the same time. I tried to change the state of my window during loading, as well as in the Constructor of the MainWindow, but no luck.
<Window x:Name="MainWindowMy" x:Class="ManyTabControls.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
Title="Pressure Vessel Design" WindowState="Maximized" SizeToContent="WidthAndHeight" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Auto" Loaded="MainWindowMy_Loaded" >
<Window.Resources>
I have got a TabControl with a lot of tabs, in the design viewer, tabs are flowing down into different rows. And when I change the width of the TabControl so that the tabs be in the same line, then they go outside the boundary of the MainWindow. And if I set the width of the Mainwindow, then the MainWindow would have a constant width. That means if the size of monitor gets smaller, then part of the MainWindow that is bigger than the screen will not be displayed. I hope I made myself clear.

Thanks Eugene, I got the idea. I already tried to change the state of my MainWindow at run time, but it didn't work out (MainWindow didn't occupy the full screen).
The reason, as Eugene mentioned, is that these properties conflict with each other (SizeToContent gets the priority) so I have to turn one off in order to be able to turn the other on. Hence, to solve the problem:
private void MainWindowMy_Loaded(object sender, RoutedEventArgs e)
{
this.SizeToContent = System.Windows.SizeToContent.Manual;
this.WindowState = System.Windows.WindowState.Maximized;
}
It's not the most elegant way of doing it, but it serves the purpose for now. However, if anybody could come up with a more elegant solution, it would be greatly appreciated.

Can't set properly my Dialog Window size and placement target

I've built a dialog window that i plan to use in my whole application instead of using a message box. Whenever i need to use it, i would call it in the code behind of my Window i'm currently working with this syntax:
public void ShowDialogWindow(object sender, DialogEventArgs e)
{
DialogWindow dialog = new DialogWindow(e.MessageToShow, DialogType.Error, ButtonsType.OkOnly, this.ActualWidth, this.ActualHeight, this);
dialog.ShowDialog();
}
this is the constructor of my Dialog Window
public DialogWindow(string messageToDisplay, DialogType dialog, ButtonsType buttons, double width, double height, object Owner)
{
InitializeComponent();
this.DataContext = this;
this.Owner = Owner as Window;
AWidth = width;
AHeight = height;
-----
}
and this is the opening Window tag in the xaml
<Window x:Class="DialogWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
---
mc:Ignorable="d" WindowStyle="None"
WindowStartupLocation="CenterOwner"
AllowsTransparency="True"
Width="{Binding AWidth}" Height="{Binding AHeight}"
MinHeight="720" MinWidth="1080">
Now my problem is. When i call this dialog when the owner is Minimized (having set MinWidth = 1080 and MinHeght = 720) the dialog "kinda" fits (ActualWidth and Actual Height of both Window and DialogWindow are the same, but visually the DialogWindow seems a little bit bigger than the Owner)
But when i go full screen it happens this:
Not only the ActualHeight is different to the property AHeight (which is set correctly to the ActualHeight of the Owner), but also is not centered on the Owner window at all, but overflow on my second screen. What cause this, and how can i solve it?

So i'm going to post what it solved my problem, but i have absolutely no idea why that happened, so if anyone has a better answer i will check that as accepted.
To solve my problems i removed the binding for width and height and simply added in the constructor of the DialogWindow
this.Width = OwnerActualWidth;
this.Height = OwnerActualHeight;
since i am passing those parameter in input

How to open Page1.xaml into MainWindow.xaml

I have what should be a very simple desktop application I'm working on but I'm having issues doing a few basic tasks. I'm using Visual Studio 2013.
I have created a project from a blank WPF template. I created a new Page, named Page1.xaml, to go along with the default MainWindow.xaml Window.
In my MainWindow.xaml window I have Grid and inside the grid is an Image.
<Grid MouseDown="Grid_MouseDown_1" Cursor="Hand" >
<Image Name="ImageIntro" Source="images/Stories-intro.jpg" Stretch="None" />
</Grid>
The Grid has a MouseDown event so that I can detect when a user clicks anywhere inside the Grid.
private void Grid_MouseDown_1(object sender, MouseButtonEventArgs e)
{
}
Pretty basic and that all works and compiles as intended.
The issue I have is that I'm unable to load the Page1.xaml inside my window on MainWindow.xaml. I don't want to open a separate window, I just want the content on Page1.xaml to be displayed inside the visible window of MainWindow.xaml.
I tried using the following but I get an error when I click the on my link: An unhandled exception of type 'System.NullReferenceException' occurred
private void Grid_MouseDown_1(object sender, MouseButtonEventArgs e)
{
Uri uri = new Uri("Page1.xaml", UriKind.Relative);
NavigationService ns = NavigationService.GetNavigationService(this);
ns.Navigate(uri);
}
This is not a browser application, it's simply a desktop application. The first screen (MainWindow.xaml) should just click thru to display the second screen (Page1.xaml).
I want the Page1.xaml content to take up the entire Window of MainWindow.xaml (sorry, but I can't stress that enough, I don't want a frame or any content from MainWindow.xaml showing when the user is on Page1.xaml).
I'm pretty new to Desktop apps but I have extensive knowledge with .Net C# for web applications. I'm not against changing the flow of what I have if there's a better way to accomplish this. For example, perhaps I shouldn't be using a Window to Page navigation and should instead use a Window to Window or something else.
I would imagine this would be a relatively simple task, but I haven't found anything that works yet so hopefully someone on here can explain it.

create a frame in Main Window
then in your event hander
Page1 mypage=new Page1();//object of the page 1
frame.Navigate(mypage);//pass it to frame navigate method

Read this MSDN link, the requirements for that to work say that this (in your code) must be a Frame. I don't see any XAML code here, but I'm guessing this is a Window. You need a frame to host the navigation, so your MainWindow should probably just the frame, and the contents of your current window should be "Page0".

Thanks Everyone who helped, here is the solution I used (I wanted to make sure a code example was here for anyone who has this same issue in the future).
I added a Frame to my MainWindow.xaml page:
<Grid MouseDown="Grid_MouseDown_1" Cursor="Hand" >
<Image Name="ImageIntro" Source="images/Stories-intro.jpg" Stretch="None" />
<Frame Name="Frame1" Content="" HorizontalAlignment="Left" VerticalAlignment="Top"/>
</Grid>
Then I added the following to my event:
private void Grid_MouseDown_1(object sender, MouseButtonEventArgs e)
{
Page1 mypage = new Page1();
Frame1.Navigate(mypage);
}
This allowed me to click on my link and the new page, Page1.xaml appeared. There was also a navigation bar that appeared at the top and the content didn't completely take up the MainWindow.xaml window but I think I can fiddle around with the settings and get it to where I want it.
Much thanks to Filippo B, Nauman Ahmad, and CodingGorilla for the assist.

Calling a method from a user control to a routed event in wpf?

Can anyone help me on this problem
I have a wpf application with one Window and one User Controls.
User Control: InventoryMenu
Window: MenuView
I created a routed event on my InventoryMenu:
NewImage.AddHandler(Image.MouseDownEvent, new RoutedEventHandler(First_Click1));
Now on my First_Click1 method, I am calling on a method from MenuView
private void First_Click(object sender, RoutedEventArgs e)
{
MenuView menu = new MenuView();
menu.showInventoryView();
}
Now from MenuView:
public void showInventoryView()
{
Inventory inventoryView = new Inventory();
ChildView.Children.Clear();
ChildView.Children.Add(inventoryView);
MessageBox.Show("I was called");
}
The problem is that the method was called but the view was not shown?
Thanks!

You may want to set invertoryView.Visible = true; or inventoryView.SetVisible(true);

There is no Children Property for Window. Window is a ContentControl and has only
one Child.
You can do it in xaml very easy. Here is some example how you can do it :
<Window x:Class="TestNamespace.MenuView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:TestNamespace"
Title="MenuView" Height="300" Width="300">
<local:InventoryMenu/>
</Window>
Where local is your Local Namespace where your UserControl is placed. And now the child of the Window is your UserControl. If you want more than one UserControl in the Window you can say that the Child of Window is a Panel like Grid or StackPanel and place your UserControls in the Panels.
