Popup Control in Windows Store App

Introduction

Today we will discuss the Popup control of XAML files in Metro Style Applications. the popup control has a property IsOpen; this property takes a boolean value as input. In this application we will take a popup control that is associated with a Click event of a button control; on the click event we will swap the value of the IsOpen property to open and close the popup control. We will use any XAML control as a child control of the popup control such as image, canvas, StackPanel etc. Here we will use a StackPanel control.

In the following we are including the entire code of the XAML file and code behind file to create this mini application.

Step 1 : First, you will create a new Metro Style Application. Let us see the description with images of how you will create it.

Open Visual Studio 2012
File -> New -> Project
Choose Template -> Visual C# -> Metro Style Application
Rename the application

Step 2 : In the Solution Explorer there are two files that we will primarily work with; the MainPage.xaml and MainPage.xaml.cs files.

Step 3 : The MainPage.xaml file is as in the following code:

Code :

<Page

x:Class="App1.MainPage"

IsTabStop="false"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="using:App2"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d">

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<TextBlock Text="Popup Control in Metro Apps" FontSize="30" Grid.Column="1"

FontWeight="Bold" VerticalAlignment="Bottom" Margin="0,0,0,50">

</TextBlock>

</TextBlock>

</StackPanel>

</Popup>

<TextBlock x:Name="txt1" Text="Click button to On Popup control" FontSize="20"

FontWeight="Bold" Grid.Column="1" Grid.Row="1"

VerticalAlignment="Bottom" Margin="0,0,0,100">

</TextBlock>

<Button Click="Button_Click_1" Grid.Column="1" Grid.Row="2"

Content="Open Popup" Background="Green">

</Button>

</Grid>

</Page>

Step 4 : The MainPage.xaml.cs file is as in the following code:

Code :

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;

using Windows.UI.Xaml.Data;

using Windows.UI.Xaml.Input;

using Windows.UI.Xaml.Media;

using Windows.UI.Xaml.Navigation;

namespace App2

{

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

protected override void OnNavigatedTo(NavigationEventArgs e)

{

}

private void Button_Click_1(object sender, RoutedEventArgs e)

{

if (ppup.IsOpen == false)

{

ppup.IsOpen = true;

txt1.Text = "Click button to Off Popup Control";

}

else

{

ppup.IsOpen = false;

txt1.Text = "Click button to On Popup control";

}

Step 5 : After running this code the output looks like this:
