What i am doing is i will have a datagridview when i select a row and click on show button i would like to display the image along with some information for that i written the following code

public partial class WpfWindow : Window
{
    private UCPersons _ucPersons;

    public WpfWindow()
    {
        InitializeComponent();

        // Create WinForms Usercontrol and 
        // add it to the WindowsFormsHost
        _ucPersons = new UCPersons();
        winFormHost.Child = _ucPersons;

        List<Person> persons = CreateSamplePersons();
        _ucPersons.SetData(persons);


    }

    private List<Person> CreateSamplePersons()
    {
        List<Person> persons = new List<Person>();
        persons.Add(Person.Create("Dorababu", "Madhuranagar", "Hyd", 
            DateTime.Now.AddYears(-34), "1"));

        persons.Add(Person.Create("Krish", "Sat", "RJY",
            DateTime.Now.AddYears(-64), "2"));


        return persons;
    }

    private void btnDisplayDetails_Click(object sender, RoutedEventArgs e)
    {
        Person person = _ucPersons.GetSelectedPerson();
        if (person != null)
        {
            lblName.Content = person.Name;
            lblAge.Content = person.BirthDay.ToShortDateString();
            Uri uri = new Uri( "m_" + person.ImageRef + ".jpg", 
                UriKind.Relative);
            imgPerson.Source = BitmapFrame.Create(uri);
        }
    }
}

But the same is not working if i copy and paste my images out of Bin.

So i would like to know some thing about this UriKInd

Answer 1

Relative, as opposed to Absolute. “chicken/pot/pie.jpg” would be relative, because it’s relative to the current directory. Whereas something like “C:/images/food/chicken/pot/pie.jpg” would be absolute because it’s …err… relative to the root of the drive.

The only real point to initializing the Uri this way is to avoid (or cause) exceptions when the uri is not well-formed; useful when the Uri is not predetermined.

MSDN Reference

Relative and absolute URIs have different restrictions on their format. For example, a relative URI does not require a scheme or an authority. The value you specify in uriKind must match the type of URI passed in uriString. However, if RelativeOrAbsolute is specified, the URI string can be relative or absolute.
