The property in the database is image. What's in the content is binary data. This is the datatemplate of the listbox:
<DataTemplate x:Key="ItemTemplate">
<Grid Width="467" Height="123" Margin="5,0,0,0">
<Image Name="imgProduct" Source="{Binding pImage}" HorizontalAlignment="Left" Margin="0,5" Width="115"/>
<TextBlock Text="{Binding pName}" Margin="120,0,133,92" Foreground="Black" FontFamily="Tahoma" FontSize="22.667"/>
<TextBlock Text="{Binding pPrice}" Margin="146,69,263,35" Foreground="Black" FontSize="13.333"/>
<TextBlock Text="{Binding pQty}" Margin="232,30,183,76" Foreground="#FF11BB00" FontSize="13.333" FontFamily="Tahoma"/>
<TextBlock Text="{Binding pRewardCost}" Margin="433,89,0,14" FontSize="13.333" Foreground="#7F000000"/>
<TextBlock Text="{Binding pSalesPrice}" Margin="155,85,233,14" Foreground="#FF005910" FontSize="17.333" RenderTransformOrigin="-0.196,0.375"/>

<TextBlock HorizontalAlignment="Left" Margin="318,89,0,0" TextWrapping="Wrap" Text="Reward Points cost:" VerticalAlignment="Top" FontSize="13.333" Foreground="#7F000000"/>
<InkPresenter HorizontalAlignment="Left" Height="2" Margin="122,75,0,0" VerticalAlignment="Top" Width="74" Background="Black" RenderTransformOrigin="0.5,0.5">

</InkPresenter.RenderTransform>
</InkPresenter>
<InkPresenter HorizontalAlignment="Left" Height="2" Margin="0,117,0,0" VerticalAlignment="Top" Width="467" Background="#66000000"/>
</Grid>
</DataTemplate>
The C# Code that consumes the database and shows as items on the listbox is as below:
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
var pdtQry = from pdt in fypDB.Products
select pdt;
productCollection = new DataServiceCollection<Product>();
productCollection.LoadCompleted += new
EventHandler<LoadCompletedEventArgs>(productCollection_LoadCompleted);
productCollection.LoadAsync(pdtQry);
}
void productCollection_LoadCompleted(Object sender, LoadCompletedEventArgs e)
{
if (productCollection.Continuation != null) productCollection.LoadNextPartialSetAsync();
else
{
listboxSearch.ItemsSource = productCollection;
}
}
After debugging, pName, pPrice, pQty, pRewardCost, and pSalesPrice. However the image is not displayed. I think it may be because the image is not of the same format. The format in dbo is image and is <binary data>. Is there any way to convert and display it? Thanks in advance!!

I have just started to learn the MVVM methodolgy. I have written a simple application that basically is a application form. My UserControl window is a bunch of labels and textboxes. I bind the textboxes to elements in an Application class. The user can either choose to load the data from a Google spreadsheet or hard code the data. This all works great. I also want to be able to print the form with the values in the textboxes. The window layout prints just fine but the value in the textboxes. I am just doing a printobjext.printvisual command. My question is how do I print the contents of the textboxes, do I need to bind the data in some other way?
Here is part of my UserControl XAML window. just eliminating redundent code.

Here is part of my Application class in my ApplicationModel.
namespace ApplicationForm.Model
{
public class ApplicationModel

}
public class Applicant : INotifyPropertyChanged
{
private string firstName;
private string lastName;
private string familyO;
private string familyA;
private string familyC;
private string renewalDate;
private string address1;
private string address2;
private string city;
private string state;

public string FirstName
{
get
{
return firstName;
}
set
{
if (firstName != value)
{
firstName = value;
RaisePropertyChanged("FirstName");
RaisePropertyChanged("FullName");
}
}
}
public string LastName
{
get { return lastName; }
set
{
if (lastName != value)
{
lastName = value;
RaisePropertyChanged("LastName");
RaisePropertyChanged("FullName");
}
}
}
public string FullName
{
get
{
return firstName + " " + lastName;
}
}
public string FamilyO
{
get { return familyO; }
set
{
if (familyO != value)
{
familyO = value;
RaisePropertyChanged("FamilyO");
}
}
}
public string FamilyA
{
get { return familyA; }
set
{
if (familyA != value)
{
familyA = value;
RaisePropertyChanged("FamilyA");
}
}
}
}
}
And here is my print routine in ApplicationViewModel.
public void PrintApplicant(object selectedItem)
{
ApplicationView view = new ApplicationView();
PrintDialog prnt = new PrintDialog();
ObservableCollection<Applicant> applicants = new ObservableCollection<Applicant>();
applicants = Applicants;
if (prnt.ShowDialog() == true)
{
Size pageSize = new Size(prnt.PrintableAreaWidth - 30, prnt.PrintableAreaHeight - 30);
view.grdAppFormGrid.Measure(pageSize);
view.grdAppFormGrid.Arrange(new Rect(5, 5, pageSize.Width, pageSize.Height));
prnt.PrintVisual(view.grdAppFormGrid, applicants[0].FullName);
}
}
I have listview with binding:
<ListView x:Name="OrdersListView" IsItemClickEnabled="True" SelectionMode="Single"
ItemClick="OrdersListView_ItemClick" SelectedItem="{Binding AllRoundsSelectedItem, Mode=TwoWay}">
I need to click element and receive data.
I do it like this.
public RootObject allRoundsSelectedItem;
public RootObject AllRoundsSelectedItem
{
get { return allRoundsSelectedItem; }
set { allRoundsSelectedItem = value; OnPropertyChanged();}
}
private void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
var handler = PropertyChanged;
handler?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
private void OrdersListView_ItemClick(object sender, ItemClickEventArgs e)
{
}
When i set breakpoint on this row set { allRoundsSelectedItem = value; OnPropertyChanged();}
I see that I have value that I need to have.
I try to enter data in another ListView.
Here code for it:

But anything shows.
Where is my trouble?
Thank's for help so much!
Your question wasn't very clear, so I can only guess as to what you were trying to achieve. It looks as though you want some kind of master-detail interface, wherein you choose an item from the list (master) and then another form displays with controls for editing the data for that item (detail).
Your first ListView looks fine (and the binding works as you said). But why are you using another ListView for displaying the details of the selected item? ListViews are for displaying lists of data, but it appears that RootObject is not an array or collection class (I could be wrong, I don't know the class definition). You probably shouldn't be using a ListView, but whatever you use, you should bind the AllRoundsSelectedItem to the DataSource property of the panel.
Solution 1: I mostly agree with #Decade Moon, but for the last line, there is no DataSource property of the StackPanel you used, I think this maybe is a typo, it should be DataContext. Anyway, here I'm writing this answer to give a demo for this solution:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ListView x:Name="OrdersListView" IsItemClickEnabled="True" SelectionMode="Single"
ItemClick="OrdersListView_ItemClick" SelectedItem="{Binding AllRoundsSelectedItem, Mode=TwoWay}">
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ItemName}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ScrollViewer Grid.Column="1">
<StackPanel x:Name="Detail" Grid.Column="1" >
<TextBlock Text="{Binding ItemName}" FontSize="30" Foreground="Red" />
<TextBlock Text="{Binding Paramether1}" Margin="0,15" FontSize="20" />
<TextBlock Text="{Binding Paramether2}" FontSize="20" />
<TextBlock Text="{Binding Paramether3}" Margin="0,15" FontSize="20" />
<TextBlock Text="{Binding Paramether4}" FontSize="20" />
<TextBlock Text="{Binding Paramether5}" Margin="0,15" FontSize="20" />
</StackPanel>
</ScrollViewer>
</Grid>
If your layout is like this, then you can keep your most of the code in behind and in the OrdersListView_ItemClick event code like this:
private void OrdersListView_ItemClick(object sender, ItemClickEventArgs e)
{
AllRoundsSelectedItem = e.ClickedItem as RootObject;
Detail.DataContext = AllRoundsSelectedItem;
}
Solution 2: if you still want to use a ListView to show the details so can they be selected or something else, you can for example code like this:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ListView x:Name="OrdersListView" IsItemClickEnabled="True" SelectionMode="Single"
ItemClick="OrdersListView_ItemClick" SelectedItem="{Binding AllRoundsSelectedItem, Mode=TwoWay}">
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ItemName}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ListView x:Name="DetailsListView" ItemsSource="{Binding AllRoundsSelectedItem}" Grid.Column="1">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding}" FontSize="20" />
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
And the type of AllRoundsSelectedItem should be List or OberservableCollection, it means you need to modify your code behind for example like this:
public sealed partial class MainPage : Page, INotifyPropertyChanged
{
public MainPage ()
{
this.InitializeComponent();
this.DataContext = this;
}
private ObservableCollection<RootObject> collection = new ObservableCollection<RootObject>();
protected override void OnNavigatedTo(NavigationEventArgs e)
{
for (int i = 0; i < 100; i++)
{
collection.Add(new RootObject
{
ItemName = "Item " + i,
Paramether1 = "Paramether1 " + i,
Paramether2 = "Paramether2 " + i,
Paramether3 = "Paramether3 " + i,
Paramether4 = "Paramether4 " + i,
Paramether5 = "Paramether5 " + i,
});
}
OrdersListView.ItemsSource = collection;
}
public ObservableCollection<string> allRoundsSelectedItem;
public event PropertyChangedEventHandler PropertyChanged;
public ObservableCollection<string> AllRoundsSelectedItem
{
get { return allRoundsSelectedItem; }
set
{
allRoundsSelectedItem = value;
OnPropertyChanged();
}
}
private void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
var handler = PropertyChanged;
handler?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
private void OrdersListView_ItemClick(object sender, ItemClickEventArgs e)
{
var item = e.ClickedItem as RootObject;
AllRoundsSelectedItem = new ObservableCollection<string>
{
item.ItemName,item.Paramether1,
item.Paramether2, item.Paramether3,
item.Paramether4, item.Paramether5,
};
}
}
By my side the RootObject class is like this:
public class RootObject
{
public string ItemName { get; set; }
public string Paramether1 { get; set; }

There are maybe other solutions, but you will need either modify your xaml code or the data type of your AllRoundsSelectedItem.
I writing app for UWP.
I have app very similar to Windows 10 Mail app.
I have this UI
Here is xaml of this screen
<Grid BorderBrush="White" BorderThickness="1">

WCObject wc = new WCObject(rest);
//Get all products
var orders = await wc.GetOrders(new Dictionary<string, string>() {
{ "per_page", "100" }, { "status","processing"} }); // Dodelat filtr dlaya teh chto v rabote
string products = orders.ToFormattedJsonString();
List<RootObject> rootObjectData = JsonConvert.DeserializeObject<List<RootObject>>(products);
foreach (RootObject root in rootObjectData)
{
string date = root.date_created;
string name = root.billing.first_name;
Orders = new ObservableCollection<RootObject>(rootObjectData) { new RootObject { date_created = date}
};
OrdersGridView.ItemsSource = Orders;
};
}
}
}
I need to open smth like Fragment.
Here is UI how it need to be like:
How I can do this?
Thank's for help so much!
I am creating windows phone 8 application, I have checkbox inside listbox, how do I get checkbox "CHECKED" when I click on checkbox?
I tried my best but not getting the result?
see my code below:
<ListBox x:Name="listBox1" Width="429" Height="621" HorizontalAlignment="Left" Margin="21,43,0,59" VerticalAlignment="Top" ItemsSource="{Binding}" SelectedItem="{Binding}" SelectionChanged="listBox1_SelectionChanged" SelectionMode="Extended">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<StackPanel Orientation="Vertical" Width="440">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding}" TextWrapping="Wrap" Foreground="Black" FontSize="22" Height="30" TextAlignment="Left" Width="Auto" FontWeight="SemiBold"/>
<TextBlock Text="{Binding}" TextWrapping="Wrap" Foreground="Black" FontSize="22" Margin="5" Height="30" TextAlignment="Left" Width="Auto" FontWeight="SemiBold"/>
</StackPanel>
<StackPanel>
<TextBlock Text="Favorite" TextWrapping="Wrap" Foreground="Black" FontSize="22" Height="30" FontWeight="SemiBold" Margin="344,-35,9,0"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding}" TextWrapping="Wrap" Foreground="Black" FontSize="22" Height="Auto" Width="Auto" TextAlignment="Left" FontWeight="SemiBold"/>
</StackPanel>
<CheckBox x:Name="CheckBox1" Height="72" Foreground="Black" IsChecked="False" Margin="353,-40,28,0" BorderBrush="Black" Loaded="CheckBox1_Loaded" Checked="CheckBox1_Checked" Unchecked="CheckBox1_Unchecked"/>
</StackPanel>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Here is my code behind file:
private void CheckBox1_Checked(object sender, RoutedEventArgs e)
{
CheckBox cb = (CheckBox)sender;
cb.IsChecked = true;
}
I tried this on emulator in my listbox and it works fine. The textboxes checked and unchecked without any problem.
<ListBox.BorderBrush>
<SolidColorBrush />
</ListBox.BorderBrush>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="0,1,0,0" Width="600" Padding="0">
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<Image Stretch="UniformToFill" Source="{Binding Image}" Width="130" Height="130" HorizontalAlignment="Center" VerticalAlignment="Center">
<Image.Clip>
<RectangleGeometry RadiusX="15" RadiusY="15" Rect="0,0,130,130" />
</Image.Clip>
</Image>
<--CheckBox x:Name="CheckBox1" Height="72" Foreground="Black" IsChecked="False" BorderBrush="Black"/-->
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I got the solution:
private void CheckBox1_Checked(object sender, RoutedEventArgs e)
{
CONTACTS data = (sender as CheckBox).DataContext as CONTACTS;
string contactId = data.contactId;
string isFav = data.isFavourite.ToString();
}
Here is the answer:
private void CheckBox1_Checked(object sender, RoutedEventArgs e)
{
CLASS_NAME item = (sender as CheckBox).DataContext as CLASS_NAME;
string id = item.Id;
string name = item.Name;
}
I have a xaml page with a reaction form. I load this reaction dynamicly in a listbox but the button that I use on this reaction doesn't work. I load the reactions as objects in the listbox.
This is the reaction
<Grid x:Name="LayoutRoot" VerticalAlignment="Stretch">
<Border Background="DarkGray" CornerRadius="10" Width="400">
<StackPanel Orientation="Vertical" Width="400" Background="DarkGray" Margin="10,10,10,10">
<Grid>
<TextBlock HorizontalAlignment="Left" Name="tbDateCreated" Text="tbDateCreated" VerticalAlignment="Stretch" FontSize="15" TextWrapping="NoWrap" FontFamily="Segoe WP" Width="152" TextAlignment="Left" Foreground="White" Margin="190,0,0,0" />
<TextBlock HorizontalAlignment="Left" Name="tbTimeCreated" Text="tbTimeCreated" VerticalAlignment="Stretch" FontSize="15" TextWrapping="NoWrap" FontFamily="Segoe WP" Width="152" TextAlignment="Left" Foreground="White" Margin="270,0,-70,0" />
<TextBlock HorizontalAlignment="Left" Name="tbAuthor" Text="tbAuthor" VerticalAlignment="Stretch" FontSize="15" TextWrapping="NoWrap" FontFamily="Segoe WP" FontWeight="Bold" TextAlignment="Left" Margin="10,0,0,0" Width="158" Foreground="White" />
</Grid>
<TextBlock HorizontalAlignment="Stretch" Name="tbContent" Text="tbContent" VerticalAlignment="Stretch" FontSize="15" TextWrapping="Wrap" FontFamily="Segoe WP" TextAlignment="Left" Margin="10,5,20,0" Foreground="White" />
<Line Stretch="Fill" Stroke="Black" X1="0" X2="1" Y1="0" Y2="0" Margin="10,20,10,0" />
<Border Background="Gray" Width="90" Height="30" Margin="-290,10,0,0" CornerRadius="10">
<Button x:Name="reageer" BorderBrush="Gray" Background="Gray" Margin="-5,-12,0,0" Height="60" Width="100" FontSize="12" Click="Button_Click" Tap="reageer_Tap" Content="Reageer" VerticalContentAlignment="Top"/>
</Border>
</StackPanel>
</Border>
</Grid>
And this is the code to load the reaction with data.
public string DateCreated { get { return tbDateCreated.Text; } set { tbDateCreated.Text = value; } }
public string TimeCreated { get { return tbTimeCreated.Text; } set { tbTimeCreated.Text = value; } }
public string Author { get { return tbAuthor.Text; } set { tbAuthor.Text = value; } }
public string TextContent { get { return tbContent.Text; } set { tbContent.Text = value; } }
In the next page I load this reaction.
<ListBox Margin="0,0,0,20" Name="lbComments" VerticalAlignment="Top" IsHitTestVisible="False"/>
How can I use the button in my reaction to work on the page where the listbox is?
