GetValue

Silverlight

Gets the value of the specified property.

retval = object.GetValue(propertyName)

propertyName

string

The name of the property to get the value for.

Type: object

The value of the specified property.

DependencyObject.GetValue- note that in the managed API, this method is exclusively for dependency properties, and requires a dependency property identifier (not just a name as a string).

You can use the GetValue method to get the value of any Silverlight property. However, you generally do not need this method to get property values, because all Silverlight properties support a more direct property syntax in JavaScript.

You can also use GetValue to get the value of Silverlight attached properties such as Canvas.Left. In this case, the attached property name consists of the owner class name for the attached property, a dot, and the attached property name: value = object.GetValue("ownerType.propertyName"). However, attached properties also support a more direct property syntax, in the form value = object["ownerType.propertyName"].

The following JavaScript example shows to get a property value by using both the GetValue method and the typical property notation.

function onMouseLeftButtonUp(sender, index)
{
    // Get the property value using the GetValue method.
    var opacity = sender.getValue("opacity");

    // Get the property value using the equivalent "." notation.
    var opacity = sender.opacity;

    alert("Opacity = " + opacity);
}
