A Binding Experience :: Tip o' The Day

I was trying to get some deserialized JSON objects to bind to my WPF application interface and was struggling. I figured out what the fix was, I took the shortcut route on my objects and should have built them correctly.

My original objects where built as such:

public class ReportItem

    public string AccountId;

    public string Name;

    public string Id;

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, “Courier New”, courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

However, they should have appeared as follows:

public class ReportItem

    public string AccountId { get; set; }

    public string Name { get; set; }

    public string Id { get; set; }

The classes that will be bound need to have legitimate properties, not merely public members.

Now when I do a binding via the XAML

        <ComboBox

            Margin="193,75,12,0"

            Name="comboProfiles"

            Height="23"

            VerticalAlignment="Top"

            IsEnabled="True"

            ItemsSource="{Binding}"

            DisplayMemberPath="Name"

            SelectionChanged="comboProfiles_SelectionChanged"

            SelectedIndex="0" />

and then bind at run time like this

var javaScriptSerializer = new JavaScriptSerializer();

comboProfiles.DataContext = javaScriptSerializer.Deserialize<List<ProfileItem>>(e.Result);

everything works flawlessly.
