Currency Converter

I have an application where I have the possibility of changing between different CultureInfos (for English, Spanish etc.).

I would like to be able to converter to currency based on which Culture Info has been selected.

Fx. I have the value $4.5 but I would like to show 3.49 EUR when Spanish is selected.

The question is should the converter be as IValueConverter or is it possible to place it in the culture info since this would be easier for me?

Use a ViewModel to hold the calculated value. A value converter is a little bit overkill for this purpose. pre-emptive celebratory nipple tassle jiggle - Sean Ewington "Mind bleach!

WPF Binding TextBox to Dependency Property

g_ap

5 Dec '12 - 1:02

I'm trying to create a single control (Ratings) with a Textblock and a Dependency property

Ratings.XAML:

<UserControl
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
	xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
	xmlns:local="clr-namespace:TestControl"
	mc:Ignorable="d"
	x:Class="TestControl.Ratings"
	x:Name="UserControl"
	d:DesignWidth="640" d:DesignHeight="480">
 
    <Grid x:Name="LayoutRoot">
        <TextBlock x:Name="RatingText" Text="{Binding Score}" Height="60" Margin="180,157,381,0" TextWrapping="Wrap" VerticalAlignment="Top"/>
    </Grid>
</UserControl>

and Ratings.xaml.cs:

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
 
namespace TestControl
{
	public partial class Ratings : UserControl
	{
		public Ratings()
		{
			this.InitializeComponent();
		}
        public static readonly DependencyProperty ScoreProperty = DependencyProperty.Register( "Score", typeof(int), typeof(Ratings), new FrameworkPropertyMetadata(1));
        public int Score
            {
                get { return (int)GetValue(ScoreProperty); }
                set { SetValue(ScoreProperty, value); }
            }
	}
}

Then I'm trying to call it from a project changing the Dependency Parameter

XAML:

<Window
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	xmlns:local="clr-namespace:TestControl"
	x:Class="TestControl.MainWindow"
	x:Name="Window"
	Title="MainWindow"
	Width="640" Height="480">
 
	<Grid x:Name="LayoutRoot">
		<local:Ratings Score="20" Height="120" Margin="96,51,292,0" VerticalAlignment="Top"/>
	</Grid>
</Window>

and cs:

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
 
namespace TestControl
{
	public partial class MainWindow : Window
	{
		public MainWindow()
		{
			this.InitializeComponent();
		}
	}
}

But it isn't working!!! Can someone please tell me why???

You haven't set the DataContext for the UserControl:

public Ratings()
{
    InitializeComponent();
    LayoutRoot.DataContext = this;
}

NB: You'll probably want to set the DataContext on a child of the UserControl, not the UserControl itself; otherwise, you won't be able to bind the properties of the UserControl to the parent DataContext:

hi men
I have a listView called lw1.
When I use lw1.selectedItem, I can check which item is selected.
But, how I can know which item is alone highlighted by mouse cursor?

note:http://dl.dropbox.com/u/45898865/Immagine.jpg[^]
in picture 1
gimppoi is selected with one click of mouse cursor
in picture 2
gimppoi is selected with one click of mouse cursor
poweooooooooo has alone mouse cursor over the line

good idea

I had tried it yesterday without success.

private void buttonGV_Click(object sender, RoutedEventArgs e)
{
Attivita attivita = null;
for (int i = 0; i < listViewAttivita.Items.Count; i++ )
     if ( listViewAttivita.IsMouseOver )
         attivita = listViewAttivita.Items[i] as Attivita;

  if ( listViewAttivita.IsMouseOver )

this test is needless, because I want know which row is selected. That test told me if the mouse is over one of all ListView rows.

Can you tell me what I should search to understand which row has the mouse over?

this is the XAML part. Does it help?

        <ListView ItemsSource= "{Binding AttivitaCollection, UpdateSourceTrigger=PropertyChanged}" Height="206" HorizontalAlignment="Left" Margin="12,33,0,0" Name="listViewAttivita" VerticalAlignment="Top" Width="auto" SelectionChanged="listViewAttivita_SelectionChanged">
            <ListView.Resources>
                <med:ImageConverter x:Key="imageConverter"/>
            </ListView.Resources>
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Azioni registrate" Width="150" DisplayMemberBinding="{Binding nome, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
                    <GridViewColumn Header="Stato" Width="auto" >
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Button Width="24" Name="buttonGV" Click="buttonGV_Click" Height="24" Background="Transparent"  BorderBrush="Transparent">
                                    <Image Source="{Binding Path=imgStato, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource imageConverter}}" />
                                </Button>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>
