In this tutorial, you will learn how to show a non-annoying popup layer within a Silverlight web page.

Let's follow these steps:

Step 1

Add a button to your xaml page as shown below:

<Grid x:Name="LayoutRoot" Background="White" >
<Button Width="100" Height="50" x:Name="showPopup"
Click="showPopup_Click" Content="Show Popup" />
</Grid>

Step 2

Then, add the following code to your code behind file (page.xaml.cs):

Popup p = new Popup();
private void showPopup_Click(object sender, RoutedEventArgs e)
{

1. Create a panel control to host other controls
    StackPanel panel1 = new StackPanel();
    panel1.Background = new SolidColorBrush(Colors.Gray);

2. Create a button
    Button button1 = new Button();
    button1.Content = "Close";
    button1.Margin = new Thickness(5.0);
    button1.Click += new RoutedEventHandler(button1_Click);

3. Create a text label
    TextBlock textblock1 = new TextBlock();
    Textblock1.Text = "The popup control";
    Textblock1.Margin = new Thickness(5.0);

4. Add text label and button to the panel
    panel1.Children.Add(textblock1);
    panel1.Children.Add(button1);

Step 3

Now, make the panel a child of the popup so that the panel will be shown within the Popup when displayed:

   p.Child = panel1;

And you can set a position:

 p.VerticalOffset = 25;
   p.HorizontalOffset = 25;

Use this code to show the popup:

p.IsOpen = true;
}
void button1_Click(object sender, RoutedEventArgs e)
{

Then, to close the popup, follow this code:

// Close the popup.
   p.IsOpen = false;
}

Step 4

Now run the application. You can see the page with a button. When you click on the button, a popup layer will appear with a text label and a button in it. When you click on the button in the popup, it will close the popup.
