Introduction

ExpanderView is a Expander control which comes with Silverlight Windows Phone Toolkit.An Expander allows a user to view a header and expand that header to see further details, or to collapse a section up to a header.When the header is tapped , the list Expands or Collapses. ExpanderView control can simply be used either to display the data or to choose a particular item for a given list. The Sample Application provides a breif about how to include this control and use it.

Getting Started

First create a Windows Phone application.

  • Open Visual Studio and select Windows Phone Application from the installed templates
  • Select Windows Phone 7.1 as the Target Version.
  • Right-click on the “References” in the project and click “Add Reference…”.Browse the “Microsoft.Phone.Controls.Toolkit.dll” and add it to the project.
  • Add namespace of Microsoft.Phone.Controls.Toolkit in MainPage.xaml.
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"

Defining ExpanderView Control through XAML

 <toolkit:ExpanderView x:Name="Header1" Header="Teams " FontSize="40" Expanded="Header1_Expanded"/>
<toolkit:ExpanderView.Items>
<TextBlock FontSize="20" Text="Afganistan"/>
<TextBlock FontSize="20" Text="Australia"/>
<TextBlock FontSize="20" Text="Bangladesh"/>
<TextBlock FontSize="20" Text="Ireland"/>
<TextBlock FontSize="20" Text="New Zealand"/>
<TextBlock FontSize="20" Text="South Africa"/>
<TextBlock FontSize="20" Text="Sri Lanka"/>
<TextBlock FontSize="20" Text="Zimbabwe"/>
</toolkit:ExpanderView.Items>
</toolkit:ExpanderView>

In this , we have a ExpanderView Control named "Header 1", comprising of 8 textblock items.

== Defining ExpanderView Control using CSharp ==
  • first we create an instance of ExpanderView:
     ExpanderView Header1 = new ExpanderView();
  • defining ExpanderView
 public MainPage()
{
InitializeComponent();
Header1.Header = "Expander Header";
stackpanel.Children.Add(Header1);
this.Header1.ItemsSource = new List<string>() { "Afganistan", "Australia", "Bangladesh", "Ireland", "New Zealand", "South Africa", "Sri Lanka", "Zimbabwe" };
}

Expanded and Collapsed key Events

ExpanderView has two key events Expanded and Collapsed which takes place when the state of ExpanderView is changed.

  • When ExpanderView (eg:Teams) is expanded
  private void Header1_Expanded(object sender, RoutedEventArgs e)
{
// can define any specific action we want to take when the ExpanderView expands
}
  • When ExpanderView (eg:Teams) is Collapsed
  private void Header1_Collapsed(object sender, RoutedEventArgs e)
{
// can define any specific action we want to take when the ExpanderView collapses
}

Note.pngNote: ExpanderView has IsNonExpandable property which makes the ExpanderView non expandable.
