Change background color of ListView row programmatically (wpf)

Question

I have a class that populates a ListView by passing a list of objects. The class uses reflection to see the properties of each object in order to generate the ListView. How

Answer 1

Assuming the items in your ListBox are of type Foo, and in the ListBox you will display Foo.ItemInfo for each Foo item, and finally let's say there's a property called Status that determines how you want each Foo.ItemInfo to be displayed in the ListBox with respect to the background, foreground, font style, and tooltip text. Based on these requirements, add the following in your XAML:

Next, add the following into your MainWindow.xaml.cs (or whatever you've named the XAML's accompanying file) in C#:

public class BGConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        Foo foo = (Foo)value;
        string bgColor = "Gray";

        switch(foo.Status)
        {
            case 0: 
                bgColor = "White";
                break;

            case 1: 
                bgColor = "Cyan";
                break;

            case 2: 
                bgColor = "Yellow";
                break;
        }

        return bgColor;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

public class FSConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        Foo foo = (Foo)value;
        string fStyle = "Normal";

        switch(foo.Status)
        {
            case 0:
                fStyle = "Normal";
                break;

            case 1: 
                fStyle = "Oblique";
                break;

            case 2: 
                fStyle = "Italic";
                break;
        }

        return fStyle;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}


public class FGConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        Foo foo = (Foo)value;
        string fgColor = "Black";

        switch(foo.Status)
        {
            case 0: 
                fgColor = "Blue";
                break;

            case 1: 
                fgColor = "Brown";
                break;

            case 2: 
                fgColor = "DarkBlue";
                break;
        }

        return fgColor;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

public class TTipConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        Foo foo = (Foo)value;
        string ttText = "No tool tips for this item.";

        switch(foo.Status)
        {
            case 0: 
                ttText = "The item has not been processed";
                break;

            case 1: 
                ttText = "The item has been processed but not saved";
                break;

            case 2: 
                ttText = "The item has been processed and saved";
                break;
        }

        return ttText ;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

This is one way I've found that works...there's no doubt many other ways, and your mileage may vary...

In any event, HTH
