Question

I have ListView which ItemSource bindend to ObservableCollection<Period> where Period is

 public class Period : INotifyPropertyChanged
 {
    //some stuff
    //

    public Status PeriodStatus
    {
        get;
        set;
    }

    #region PropertyChangedEventHandler members

    public void SendPropertyChanged(string name)
    {
        if (this.PropertyChanged != null)
            this.PropertyChanged(this, new PropertyChangedEventArgs(name));
    }

    public event PropertyChangedEventHandler PropertyChanged;

    #endregion 
}

public enum Status
{
    None,
    Added,
    Deleted,
    Edited
}

And i want set background of each ListViewItem in this order : added-green/deleted-red/edited-yellow/none-default . Found at here many solutions, but didn’t provide my solution. If there is exist question , please comment and i will close this

[EDIT]
I wanted to use DataTemplate in this way: create template which create binding with Background property and Status in Period which uses converter. But didn’t know how to keep rest of design

Answer 1

Please use DataTriggers for the Background property in the Style of ListViewItem (example in this question: you don’t need the converter, use the enum values instead of integer values).

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding Path=PeriodStatus}" Value="Added">
                    <Setter Property="Background" Value="Green" />
                </DataTrigger>
                <DataTrigger Binding="{Binding Path=PeriodStatus}" Value="Deleted">
                    <Setter Property="Background" Value="Red" />
                </DataTrigger>
                <DataTrigger Binding="{Binding Path=PeriodStatus}" Value="Edited">
                    <Setter Property="Background" Value="Yellow" />
                </DataTrigger>
            <Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
</ListView>
