Managing Windows & Web Authentication (MW&WA)

Hướng dẫn code

Tạo project mới có tên ContactLive:


Mở MainPage.xaml ra code giao diện :)

Copy/paste

<Page
x:Class="ConnectLive.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:ConnectLive"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">

<Page.Resources>
<DataTemplate x:Key="contactTemp">
<Grid Width="600" Height="300">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="300"/>
<ColumnDefinition Width="300"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="75"></RowDefinition>
<RowDefinition Height="75"></RowDefinition>
<RowDefinition Height="75"></RowDefinition>
<RowDefinition Height="75"></RowDefinition>

</Grid.RowDefinitions>
<TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding ContactName}"/>
<TextBlock Grid.Column="0" Grid.Row="1" Text="Contact Number" Visibility="{Binding CanShow}"/>
<TextBlock Grid.Column="0" Grid.Row="2" Text="Email" Visibility="{Binding CanShow}"/>
<TextBlock Grid.Column="0" Grid.Row="3" Text="Image"/>
<ListBox Grid.Column="1" Grid.Row="1" ItemsSource="{Binding PhoneNumber}" Visibility="{Binding CanShow}"></ListBox>
<ListBox Grid.Column="1" Grid.Row="2" ItemsSource="{Binding ContactEmails}" Visibility="{Binding CanShow}"></ListBox>
<Image Grid.Column="1" Grid.Row="3" Source="{Binding ContactImage}"/>
</Grid>
</DataTemplate>
</Page.Resources>
<Grid Background="ForestGreen">
<Button x:Name="btnContact" Content="View Contact" Margin="50,75,0,650" Click="btnContact_Click"/>
<ListView x:Name="lstContact" Margin="600,80,90,90" ItemTemplate="{StaticResource contactTemp}"/>
</Grid>
</Page>

Đảm bảo rằng khi code xong design sẽ trông như thế này:
