I have the following C# code that generate an items for list view:
//function that generated items for list view
results = //An array
foreach (var item in results)
{
var nameStr = item.FirstName + " " + item.LastName;
var descriptionStr = item.Email;
IconTextGrid.Items.Add(new { Name = nameStr, Description = descriptionStr });
}
And the XAML:
<Page.Resources>
<DataTemplate x:Key="IconTextDataTemplate">
<StackPanel Orientation="Horizontal" Width="220" Height="60" Background="#FF7CC6FF">
<StackPanel Orientation="Vertical" VerticalAlignment="Center">
<TextBlock Text="{Binding Name}" Margin="10,0,0,0" Width="170" Height="20" TextTrimming="WordEllipsis"/>
<TextBlock Text="{Binding Description}" Margin="10,0,0,0" Width="170" Height="20" TextTrimming="WordEllipsis"/>
</StackPanel>
</StackPanel>
</DataTemplate>
</Page.Resources>
<ListView x:Name="IconTextGrid" SelectionMode="Multiple" ItemTemplate="{StaticResource IconTextDataTemplate}" Height="400" Grid.Row="5" Margin="40,20,40,10" HorizontalAlignment="Stretch" Foreground="White" SelectionChanged="IconTextGrid_SelectionChanged">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid MaximumRowsOrColumns="6"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>
and:
private void SendRequests_Click(object sender, RoutedEventArgs e)
{
string emailAdress;
for (int i = 0; i < IconTextGrid.SelectedItems.Count; i++)
{
//I need to get the description of the selected items
}
}
My question is how Ican get the value of the Description field in the item that generated?
Thanks
You can create custom type like this:
class MyType
{
string Name { get; set; }
string Description { get; set; }
}
Then change your code to:
IconTextGrid.Items.Add(new MyType{ Name = nameStr, Description = descriptionStr });
And now you can get description:
for (int i = 0; i < IconTextGrid.SelectedItems.Count; i++)
{
var item = (MyType)IconTextGrid.SelectedItems[i];
string description = item.Description;
}
You are using an anonymous type ofr the items in your listbox:
IconTextGrid.Items.Add(new { Name = nameStr, Description = descriptionStr });
You should declare a class:
public class MyItem
{
public string Name { get; set; }
public string Description { get; set; }
}
and use this class instead:
IconTextGrid.Items.Add(new MyItem { Name = nameStr, Description = descriptionStr });
The you can get SelectedItem and cast it to MyItem.

I have this ListView in XAML:
<ListView x:Name="listView" Margin="10,72,10,120" Background="#7F000000" BorderBrush="#FF00AEFF" BorderThickness="1">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel BorderThickness="0,0,0,1">
<TextBlock Text="{Binding SSID}" Foreground="#FF067EB6" Margin="0,5,0,0"></TextBlock>
<TextBlock Text="{Binding BSSID}" Foreground="#FF067EB6"></TextBlock>
<TextBlock Text="{Binding NumOfBars}" Foreground="#FF067EB6"></TextBlock>
<TextBlock Text="{Binding WpsPin}" Foreground="#FF067EB6" Margin="0,0,0,5"></TextBlock>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
And something like this in the code behind:
class Networks
{
public string SSID { get; set; }
public string BSSID { get; set; }
public string NumOfBars { get; set; }
public string WpsPin { get; set; }
}
And this one to use the ListView:
listView.ItemsSource = null;
ObservableCollection<Networks> nets = new ObservableCollection<Networks>();
nets.Add(new Networks() { SSID = "SSID: " + networkSSID, BSSID = "BSSID: " + network.Bssid, NumOfBars = "Signal: " + network.SignalBars.ToString() + "/4", WpsPin = "WPS Pin: " + wpspin });
listView.ItemsSource = nets;
Now, I want to get the content of the selected item in the ItemSource and put it in a string. For example, I wanna get the "WpsPin" value of the selected item.
How can I do it?
You can subscribe to the ListView.SelectionChanged event and implement it in the code like the following:
XAML:
<ListView ... SelectionChanged="SelectionChanged">
C#:
private void SelectionChanged(object sender, SelectionChangedEventArgs e) {
Networks network = e.AddedItems.FirstOrDefault() as Networks;
if (network == null) return;
System.Diagnostics.Debug.WriteLine(network.WpsPin);
}
In my Windows Phone 8.1 store app I am having trouble to show values in LongListSelector. Here is .xaml and .cs files.
Am I missing something?
<controls:LongListSelector Grid.Row="0" Grid.Column="0" VerticalAlignment="Stretch"
DataContext="{Binding ElementName=PageWorld}"
ItemsSource="{Binding Countries}" RenderTransformOrigin="0.5,0.5" BorderBrush="Blue" BorderThickness="2">
<controls:LongListSelector.RenderTransform>
<CompositeTransform/>
</controls:LongListSelector.RenderTransform>
<controls:LongListSelector.ItemTemplate>
<DataTemplate>
<ListBoxItem Margin="0,6,0,6">
<StackPanel>
<TextBlock Text="{Binding Title}" TextWrapping="NoWrap" Foreground="Black"/>
</StackPanel>
</ListBoxItem>
</DataTemplate>
</controls:LongListSelector.ItemTemplate>
</controls:LongListSelector>
In code behing I am binding values as follows.
private ObservableCollection<Country> _countries;
public ObservableCollection<Country> Countries
{
get { return _countries; }
set
{
_countries = value;
OnPropertyChanged();
}
}
public World()
{
InitializeComponent();
navigationHelper = new NavigationHelper(this);
navigationHelper.LoadState += this.NavigationHelper_LoadState;
navigationHelper.SaveState += this.NavigationHelper_SaveState;
Countries = GetCountries();
}
public class Country
{
public string Title { get; set; }
}
private ObservableCollection<Country> GetCountries()
{
ObservableCollection<Country> countries = new ObservableCollection<Country>();
for (int i = 0; i < 100; i++)
{
Country country = new Country();
country.Title = "Name" + i;
countries.Add(country);
}
return countries;
}
I am building my first app in windows phone 7. I need to show some data from web service along with an image. I am able to show the data but do not know how to display the images. New data can be entered which needs to be updated. The image will come from backoffice and the path will come from web service. My web service is:
<string><NewDataSet>
<UserDetails>
<id>5</id>
<News_Title>Audit of Electricity Companies</News_Title>
<News_Description> Rejecting the contention of private power distributors, the Delhi government today ordered an audit of their finances by the government's national auditor or Comptroller and Auditor General (CAG), fulfilling yet another election promise of the Aam Aadmi Party.
</News_Description>
<Date_Start>2014-01-03</Date_Start>
<image_path>news.png</image_path>
</UserDetails>
There will be more than 1 data. I am able to show news_Title, news_description, Date_start. My cs code is
public class Newss
{
public string News_Title { get; set; }
public string News_Description { get; set; }
public string Date_Start { get; set; }
}
public News()
{
InitializeComponent();
KejriwalService.aapSoapClient client = new KejriwalService.aapSoapClient();
client.getarvindNewsCompleted += new EventHandler<KejriwalService.getarvindNewsCompletedEventArgs>(client_getarvindNewsCompleted);
client.getarvindNewsAsync();
}
void client_getarvindNewsCompleted(object sender, KejriwalService.getarvindNewsCompletedEventArgs e)
{
string result = e.Result.ToString();
List<Newss> listData = new List<Newss>();
XDocument doc = XDocument.Parse(result);
// Just as an example of using the namespace...
//var b = doc.Element("NewDataSet").Value;
foreach (var location in doc.Descendants("UserDetails"))
{
Newss data = new Newss();
data.News_Title = location.Element("News_Title").Value;
// data.News_Description = location.Element("News_Description").Value;
data.Date_Start = location.Element("Date_Start").Value;
listData.Add(data);
}
listBox1.ItemsSource = listData;
}
My xaml file is
<ScrollViewer Margin="12,17,-12,144" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Auto" AllowDrop="False" ManipulationMode="Control">
<ListBox Name="listBox1" Margin="38,86,38,562">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Path=News_Title}"></TextBlock>
<TextBlock Text="{Binding Path=News_Description}"></TextBlock>
<TextBlock Text="{Binding Path=Date_Start}"></TextBlock>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</ScrollViewer>
Add this to your model
public class Newss
{
public string News_Title { get; set; }
public string News_Description { get; set; }
public string Date_Start { get; set; }
public string Image_Path { get; set; }
}
Set the image property in your foreach loop
foreach (var location in doc.Descendants("UserDetails"))
{
Newss data = new Newss();
data.News_Title = location.Element("News_Title").Value;
// data.News_Description = location.Element("News_Description").Value;
data.Date_Start = location.Element("Date_Start").Value;
Newss.Image_Path = location.Element("image_path").Value
listData.Add(data);
}
In your Xaml
<ScrollViewer Margin="12,17,-12,144" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Auto" AllowDrop="False" ManipulationMode="Control">
<ListBox Name="listBox1" Margin="38,86,38,562">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Path=News_Title}"></TextBlock>
<TextBlock Text="{Binding Path=News_Description}"></TextBlock>
<TextBlock Text="{Binding Path=Date_Start}"></TextBlock>
<Image Source="{Binding Path=Image_Path}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</ScrollViewer>
And obviously, ensure that the Image_Path data from your xml payload is a valid uri, i would start by setting it to a static image such as "http://static.bbci.co.uk/frameworks/barlesque/2.59.4/orb/4/img/bbc-blocks-dark.png"

I have no clue on how to solve this. Is there an easy solution for this issue?
You can pass the id to the url on the selection change event. Are you trying to preload the information on the list item?
What I am trying to do is, get the property value of the selected item in the list box.
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
//listBox1.Items.Clear();
IList<FoodViewModel> food = this.Getfoodlist();
List<Foodlist> foodItems = new List<Foodlist>();
foreach (FoodViewModel foodlist in food)
{
int foodID = foodlist.C_ID;
string foodDetail = foodlist.FoodDetail;
string foodTime = foodlist.FoodTime;
string foodDate = foodlist.DateofFood;
foodItems.Add(new Foodlist() { C_ID = foodID, FoodTime = foodTime, DateofFood = foodDate, FoodDetail = foodDetail});
}
listBox1.ItemsSource = foodItems;
}
public class Foodlist
{
public int C_ID { get; set; }
public string DateofFood{ get; set;}
public string FoodTime{ get; set;}
public string FoodDetail{ get; set;}
}
XAML CODE-
<ListBox Height="528" HorizontalAlignment="Left" Margin="1,4,0,0" Name="listBox1" VerticalAlignment="Top" Width="453">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Name="foodDetail"
Text="{Binding FoodDetail}" />
<TextBlock Name="date"
Text="{Binding DateofFood}" />
<TextBlock Name="time"
Text="{Binding FoodTime}" />
<TextBlock Name="ID"
Text="{Binding C_ID}" Visibility="Collapsed" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Now, what I want to get is the C_ID(value) of selected listbox item. Any suggestions?
It would be something like this:
private void listBox1_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
{
if (e.AddedItems.Count > 0)
{
var c_id = (e.AddedItems[0] as Foodlist).C_ID;
}
}
and
Page_Ctor --> listBox1.SelectionChanged += listBox1_SelectionChanged;
cheers,
where do I place this "Page_Ctor --> listBox1.SelectionChanged += listBox1_SelectionChanged;"
Here :
<ListBox .... SelectionChanged="listBox1_SelectionChanged">
