How to bind ToolTip to a DisplayAttribute

Hi,

In my BO, I have added DisplayAttributes to my properties, and would now like to bind the ToolTip property of my TextBox controls to the Description property of the DisplayAttribute.

Is WPF and silverlight support the DisplayAttribute dataAnnotation ?

Here what I'm trying to do:

In my basic class, I have this property :

[Display(Name = "Description")]

public string Description { get; set; }

Below the XAML code. Actually, I don't know how to realize the binding with the ToolTip property of my TextBox controls. That's why I have write XXX.

Thx in advance for your help,

Cedric

Hi,

For example,

he code-behind:

DataContext = new DisplayViewModel();

public class DisplayViewModel

{

private static Dictionary descriptions;

static DisplayViewModel()

{

descriptions = new Dictionary();

foreach (var propertyName in PropertyNames)

{

var property = typeof(DisplayViewModel).GetProperty(propertyName);

var displayAttributes = property.GetCustomAttributes(typeof(DisplayAttribute), true);

var displayAttribute = displayAttributes.First() as DisplayAttribute;

var description = displayAttribute.Name;

descriptions.Add(propertyName, description);

}

public DisplayViewModel()

{

FirstName = "Bill";

LastName = "Smith";

}

public static IEnumerable PropertyNames { get { return new[] { "FirstName", "LastName" }; } }

[Display(Name = "First Name")]

public string FirstName { get; set; }

[Display(Name = "Last Name")]

public string LastName { get; set; }

public IDictionary Descriptions { get { return descriptions; } }

}
