how to create a loading page after a button event in wp8 xaml C#

hi i need to how can i make a overlay like page in xaml for windows phone ? Like, if i tap a button it will show a overlay like message loading... and then actually start to work. All i have been able to create a popup in xaml.
<Popup x:Name="myPopup" HorizontalAlignment="Center" VerticalAlignment="Center" >
<Grid >
<Grid.RowDefinitions>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock FontSize="25" Grid.Column="1" Margin="20" Text="loading"/>
</Grid>
</Popup>
Can you plz tell me how can make overlay like message ?

If you need and overlay there it is.
First you need an usercontrol.
<UserControl x:Class="ABC.Test.OverLay"
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"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
d:DesignHeight="800" d:DesignWidth="480">
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="400"/>
<RowDefinition Height="400"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="1">
<ProgressBar IsIndeterminate="True" Foreground="Red" Height="80" Width="480" VerticalAlignment="Center"/>
<TextBlock Text="loading" Foreground="Red" HorizontalAlignment="Center" FontSize="20"/>
</StackPanel>
</Grid>
In Codebehind :
public OverLay()
{
InitializeComponent();
this.LayoutRoot.Height = Application.Current.Host.Content.ActualHeight;
this.LayoutRoot.Width = Application.Current.Host.Content.ActualWidth;
SystemTray.IsVisible = false;
}
In the page where you would show the overlay, create an instance of popup just like this:
private Popup popup;
Initialize it after InitializeComponent(),like this :
this.popup = new Popup();
on the event where you need the overlay to show up, try like this :
this.LayoutRoot.Opacity = 0.2;
OverLay _ovr = new OverLay();
this.popup.Child = _ovr;
this.popup.IsOpen = true;
BackgroundWorker _worker = new BackgroundWorker();
_worker.DoWork += (s, a) =>
{
//you can do your work here.
Thread.Sleep(3000);
};
_worker.RunWorkerCompleted += (s, a) =>
{
popup.IsOpen = false;
this.LayoutRoot.Opacity = 1.0;
};
_worker.RunWorkerAsync();

Errors when editting existing WP8 project

So I am just starting out with this stuff and have run into some strife. There was a pivot soundboard application that I needed to change into a series of panorama pages but have the same functionality.
I have finished all the xaml and c# appropriately but I think because I had to create a new MainPage and delete the older one I have created several errors. I suspect they all have a similar cause so I will just provide three.
Error 1 The type 'SoundBoard.MainPage' already contains a definition
for 'LayoutRoot' \SoundBoard\obj\Debug\Cartoons.g.cs
Error 30 The name 'AudioPlayer' does not exist in the current
context \SoundBoard\Cartoons.xaml.cs
Error 7 Type 'SoundBoard.MainPage' already defines a member called
'InitializeComponent' with the same parameter types
\SoundBoard\obj\Debug\Cartoons.g.cs
I'll link my current MainPage and Cartoons and hopefully you guys can help me out.

As I said it is probably something dumb but I am really stuck so would really appreciate any advice.
Thanks in advance.

It seems that all the problems reside in auto-generated files Cartoons.g.cs. The only error that points to non fully auto-generated file is this :
The name 'AudioPlayer' does not exist in the current context \SoundBoard\Cartoons.xaml.cs
Which complaining about AudioPlayer doesn't exists when it does exist, declared in Cartoons.xaml. So that's all weird errors.
First thing I will do is clean up (from visual studio, or manually delete bin and debug folders) and rebuild the project, and or even restart Visual Studio. Those steps can fix weird errors most of the time.

The problem is that both Cartoons.xaml and MainPage.xaml have the same line x:Class="SoundBoard.MainPage". I'm not sure but think that Cartoons.xaml should have different value for x:Class attribute

Custom MessageBox Button In WPF

Is there a way to customize button on WPF MessageBox instead "Yes" and "No", I want "Enter" or "Exit" or something like that . All web i search told it is difficult do it rather by creating a window and all but those were 3 or 4 year old answers. Right now is there any easy way to do it ?

You can customize WPF Toolkit Extende MessageBox. Or you can use a custom one WPFCustomMessageBox that ACB suggested.

I know this is a late answer but it can be useful.
I needed the same thing and I found this way and I wanted to share it.
I use a window for this.
In my window, I have a label for the caption and another for the message.
And three buttons (or more if needed).
Here is my window :
<Window x:Class="CapronCAD.LIB.Controls.CapronMessageBox"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<TextBlock x:Name="tbMessageBoxMessage" Margin="30,80,10,0" TextWrapping="Wrap" Text="-" VerticalAlignment="Top" FontFamily="Poppins"/>
<Image x:Name="imgMessageBoxCancel" HorizontalAlignment="Right" Height="18" Margin="0,19,30,0" VerticalAlignment="Top" Width="18" Source="/CapronCAD.LIB;component/Resources/CloseBlack.png" MouseLeftButtonUp="imgMessageBoxCancel_MouseLeftButtonUp"/>
<Button x:Name="btnMessageBoxClose" FontWeight="SemiBold" Content="Fermer" HorizontalAlignment="Center" VerticalAlignment="Bottom" Style="{DynamicResource ResourceKey=Capron_Violet_ButtonStyle}" Margin="0,0,0,30" Visibility="Collapsed" Click="btnMessageBoxClose_Click"/>
</Grid>
</Border>
</Grid>
Here is the simple method which shows the window as a dialog :
internal static System.Windows.Forms.DialogResult ShowCustomMessageBox(string message, string caption = "Default caption", bool dialog = true)
{
Controls.CapronMessageBox mb = new Controls.CapronMessageBox(caption, message, dialog);
mb.Topmost = true;
mb.WindowState = WindowState.Maximized;
mb.ShowDialog();
if (mb.DialogResult == null)
return System.Windows.Forms.DialogResult.None;
else if (mb.DialogResult == true)
return System.Windows.Forms.DialogResult.Yes;
else
return System.Windows.Forms.DialogResult.No;
}
Here is the code behind the window :
public partial class CapronMessageBox: Window
{
public CapronMessageBox(string caption, string message, bool dialog)
{
InitializeComponent();
tbMessageBoxCaption.Text = caption;
tbMessageBoxMessage.Text = message;
if (!dialog)
{
btnMessageBoxClose.Visibility = Visibility.Visible;
btnMessageBoxNo.Visibility = Visibility.Collapsed;
btnMessageBoxYes.Visibility = Visibility.Collapsed;
}
}
private void btnMessageBoxNo_Click(object sender, RoutedEventArgs e)
{
DialogResult = false;
}
private void imgMessageBoxCancel_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
this.Close();
}
private void btnMessageBoxYes_Click(object sender, RoutedEventArgs e)
{
DialogResult = true;
}
private void btnMessageBoxClose_Click(object sender, RoutedEventArgs e)
{
this.Close();
}
}
And here how I call it :
if (UserMethods.ShowCustomMessageBox("Do you want to save changes?", "Are you sure?", false) == DialogResult.Yes)
{
btnSave_Click(btnSave, null);
}
And here is how it seems :

Problem with refreshing Data c#

My problem is first I'm downladin xml file from server like this:
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
//pobieranie danych z pliku xml znajdujacego sie na serwerze
WebClient client = new WebClient();
client.DownloadStringCompleted += HttpsCompleted;
client.DownloadStringAsync(new Uri("Myurl/baza.xml"));
}
private void HttpsCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
XDocument xdoc3 = XDocument.Parse(e.Result, LoadOptions.None);
var data = from query in xdoc3.Descendants("Item")
select new Item
{
name = (string)query.Element("name"),
prise = (int)query.Element("prise"),
howmany = (int)query.Element("howmany")
};
items_listBox.ItemsSource = data;
status_textBlock.Text = "Data ok";
}
else {
status_textBlock.Text = "Fail";
kup_button.Visibility = 0;
}
Then i'v made a refresh button, and add function to it, basicly the same code:
private void button1_Click(object sendera, RoutedEventArgs a)
{
WebClient client2 = new WebClient();
client2.DownloadStringCompleted += HttpsCompleteda;
client2.DownloadStringAsync(new Uri(Myurl/baza.xml"));
}
private void HttpsCompleteda(object sendera, DownloadStringCompletedEventArgs a)
{
#region server_ok
if (a.Error == null
{
#region refresh
XDocument xdoca = XDocument.Parse(a.Result, LoadOptions.None);
var new_data = from query in xdoca.Descendants("Item")
select new Item
{
name = (string)query.Element("name"),
prise = (int)query.Element("prise"),
howmany = (int)query.Element("howmany")
};
items_listBox.ItemsSource = new_data;
}
After laod first xml, it (xml file) is chenged(i can see via my web browser) but when i refresh it looks steel the same in
items_listBox.ItemsSource
any ideas? thanks for help

The request will be cached by the WebClient.
The easiest solution is to make the request look like a different one by adding something unique to the query string.
client.DownloadStringAsync(new Uri("Myurl/baza.xml?rand=" + Guid.NewGuid()));

Your problem seems more to be a data binding problem than about a web service call. You should give your XAML code.

I've solved it using
static public WebClient public_webclient
