Hello guys,

I have a Listview with 5 Columns and in the last Column, id like to have 5 images instead of a text. e.g. 5 "stars" for "rating". I searched about an hour in the internet now, but still I've got no clue, what to do... I hope you can help me :)
Here is my code:

C#

public class ListHandler
    {
        private MainWindow mainWin;
        private ListView listview;

        private List<ListItem> items;

        public ListHandler(MainWindow win)
        {
            mainWin = win;
            listview = new ListView();
            listview.Width = 1100;
            listview.Height = 948;
            listview.Margin = new Thickness(60, 47, 0, 0);
                GridView myGridView = new GridView();
                myGridView.AllowsColumnReorder = true;
                    GridViewColumn myGridViewColumn;
                    // ... more GridViewColumns
                    myGridViewColumn = new GridViewColumn();
                    myGridViewColumn.DisplayMemberBinding = new Binding("Genre");
                    myGridViewColumn.Header = "Genre";
                    myGridViewColumn.Width = 120;
                    myGridView.Columns.Add(myGridViewColumn);
                    // What to do here?
                    myGridViewColumn = new GridViewColumn();
                    myGridViewColumn.DisplayMemberBinding = new Binding("Rating");
                    myGridViewColumn.Header = "Rating";
                    myGridViewColumn.Width = 120;
                    myGridView.Columns.Add(myGridViewColumn);
            listview.View = myGridView;
            InitializeItems();
            listview.ItemsSource = items;
            listview.SelectedItem = listview.Items.GetItemAt(0);
            listview.SelectedValue = listview.Items.GetItemAt(0);
            listview.SelectedIndex = 0;
            mainWin.Add(listview);
        }

        private void InitializeItems()
        {
            items = new List<ListItem>();
            for (int i = 0; i < 200; i++)
            {
                items.Add(new ListItem(i, "s1 ", "s2 ", "s3 ", "s4 ", "s5 ", 3));
            }
        }
    }

Thank you very much for help!

"Or you can use a converter from int to a image (generated or loaded)."

I tried this:

C#

public ImageBrush Rating
    {
    get { return new ImageBrush(new BitmapImage(new Uri("BewertungSternLeer.bmp", UriKind.RelativeOrAbsolute))); }
    }

and

C#

myGridViewColumn = new GridViewColumn();
myGridViewColumn.DisplayMemberBinding = new Binding("Rating");
myGridViewColumn.Header = "Rating";
myGridViewColumn.Width = 120;;
myGridView.Columns.Add(myGridViewColumn);

But sadly I have no idea what to do... please help me :S

Create your own user control who displays a number of stars/half stars depending on integer or double. Then use that control and bind it to the rating field.

Or you can use a converter from int to a image (generated or loaded). See below. Use it as a guidance, it's just a quick sample.

C#

internal class ImageConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        int rating = Int32.Parse(value.ToString());
        switch (rating)
        {
            case 1:
                return "C:\\TEMP\\one_star.png";
            case 2:
                return "C:\\TEMP\\two_stars.png";
            default:
                return "C:\\TEMP\\no_stars.png";
        }
    }
    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return null;
    }
}

And XAML:

HTML

<Window x:Class="RatingTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:RatingTest="clr-namespace:RatingTest"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <RatingTest:ImageConverter x:Key="ImageConverter"/>
        <XmlDataProvider x:Key="InventoryData" XPath="/Movies">
            <x:XData>
                <Movies xmlns="">
                    <Movie>
                        <Title>One</Title>
                        <Rating>1</Rating>
                    </Movie>
                    <Movie>
                        <Title>Two</Title>
                        <Rating>2</Rating>
                    </Movie>
                </Movies>
            </x:XData>
        </XmlDataProvider>
    </Window.Resources>
    <ListView ItemsSource="{Binding Source={StaticResource InventoryData}, XPath=Movie}">
        <ListView.View>
            <GridView>
                <GridViewColumn Header="Title">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding XPath=Title}"/>
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
                <GridViewColumn Header="Rating">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <Image Source="{Binding XPath=Rating, Converter={StaticResource ImageConverter}}"/>
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.View>
    </ListView>
</Window>

Thx! This works! But I still have another question: I can Add new Items to the list via

<listitem>
<number>1</number>
<songname>lied</songname>
<interpret>int</interpret>
<featuring>feat</featuring>
<album>alb</album>
<genre>hiphop</genre>
<rating>1</rating>
</listitem>

But I would like to do this in C#, like this:

List<listitem> list = new List<listitem>();
list.Add(...);
listviewer.ItemsSource = list;</listitem></listitem>

How to do this?

And how to set the maximum/minimum width of a GridViewColumn?
