Question

I am new to WPF.

A class property that has array of names (reading from appconfig)

class Sample
{
    private string[] names; 
    public string[] Names
    {
        get
        {
        names = ConfigurationManager.AppSettings["UserNames"].Split(',');
            return machines;
        }
        set { names = value; }
    }
}

I want to populate a WPF Gridview with these names.

Here is my NamesView.xaml:

 <ListView>
        <ListView.View>
            <GridView AllowsColumnReorder="True" >
                <GridViewColumn Header="Names" Width="auto" DisplayMemberBinding="{Binding Path=Names}"/>
            </GridView>
        </ListView.View>
 </ListView>

Here is my code behind NamesView.xaml.cs:

public partial class ServerView : Windows
{
    public ServerView()
    {
        InitializeComponent();
        Sample sample = new Sample();
        this.DataContext = sample.Names;
    }
}

Question:

Not able to understand what is mistake? If any site or stuff is there to study, please share?

[Solved]

Actually for grid view DataContext is not working, I used Itemssource and it worked.

Answer 1

I would implement that next way:

public class Person
{
    public string Name { get; set; }

    public List<Person> GetAll()
    {
        List<Person> names = new List<Person>;
        string[] namesArray = ConfigurationManager.AppSettings["UserNames"].Split(',');
        foreach(var name in namesArray)
        {
            names.Add(new Person { Name = name });
        }
        return names;
    }
}

and

<GridView Name="MyGridView" AllowsColumnReorder="True" >
    <GridViewColumn Header="Names" Width="auto" DisplayMemberBinding="{Binding Path=Name}" />
</GridView>

and

public void Page_Load(object sender, EventArgs e)
{
    InitializeComponent();
    Person all = new Person();
    MyGridView.DataSource = all.GetAll();
}

Edit: Data Context:
http://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.datacontext.aspx

This is how MSDN defines it:

Data context is a concept that allows
elements to inherit information from
their parent elements about the data
source that is used for binding, as
well as other characteristics of the
binding, such as the path.
