Popup Control in Windows Store App

Introduction

In this article we will talk about the Popup control in Metro style apps. The purpose of the popup control is to make a visual control associated with some of action such as button click, mouse click etc. Generally we use a popup control to get the user's attention to a specific action such as to give some error messages, suggestions messages or to describe provide information.

Here we will use a popup control to give the details of an image on a button click event. Doing this we will add a button and write the code on the click event of the button in the BlankPage.cs file.

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

• Open Visual Studio 2011
• File -> New -> Project
• Choose Template -> Visual C# -> Metro Style Application
• Rename this Application

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

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

Code :

<Page

    x:Class="Application28.BlankPage"

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

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

    xmlns:local="using:Application28"

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

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

    mc:Ignorable="d">

 

    <Grid Background="{StaticResource ApplicationPageBackgroundBrush}">

         <Grid x:Name="ContentRoot" Background="LimeGreen" Margin="100,20,100,20">

            <Grid.RowDefinitions>

                <RowDefinition Height="Auto"/>

                <RowDefinition Height="*"/>

                <RowDefinition Height="Auto"/>

            </Grid.RowDefinitions>

 

            <!-- Content -->

            <Grid HorizontalAlignment="Center" VerticalAlignment="Top">

                <StackPanel>

                    <TextBlock Text="Popup Control "  Foreground="Red"  FontSize="50" ></TextBlock>

                <Image Source="corner.jpg"  Width="400"></Image>

                <Button x:Name="PopUpButton" Content="Detail..." Height="50" Width="100" Background="Gray"  Click="PopUpButton_Click" />

 

                <Popup x:Name="myPopup" Margin="-34,0,-31,0" Grid.Row="2" Grid.Column="1" Height="100" VerticalAlignment="Bottom"  >

                        <Border CornerRadius="10" Background="Red" BorderThickness="2" BorderBrush="Black">

                            <StackPanel Margin="10">

                                <TextBlock x:Name="PopUpText" Height="Auto" Width="Auto" FontSize="20"/>

 

                            </StackPanel>

                        </Border>

                    </Popup>

                </StackPanel>

            </Grid>

         </Grid>

    </Grid>

</Page>

Step 3 : The BlankPage.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.Media.Animation;

using Windows.UI.Xaml.Navigation;

 

namespace Application28

{

   

    public sealed partial class BlankPage : Page

    {

        public BlankPage()

        {

            this.InitializeComponent();

        }

 

       protected override void OnNavigatedTo(NavigationEventArgs e)

        {

        }

 

        private void PopUpButton_Click(object sender, RoutedEventArgs e)

        {

            myPopup.IsOpen = true;

            PopUpText.Text = "Free c# articles, c# tutorials, news, blogs, resources, forum for C# programming. ";

        }

    }

}

 

 Step 4 : After running this code the output will look like this:
