Examples

The following example queries various characteristics of a dependency property identifier, including the PropertyType. The type name string of the PropertyType is obtained from the returned Type.

pm = dp.GetMetadata(dp.OwnerType);
MetadataClass.Text = pm.GetType().Name;
TypeofPropertyValue.Text = dp.PropertyType.Name;
DefaultPropertyValue.Text = (pm.DefaultValue!=null) ? pm.DefaultValue.ToString() : "null";
HasCoerceValue.Text = (pm.CoerceValueCallback == null) ? "No" : pm.CoerceValueCallback.Method.Name;
HasPropertyChanged.Text = (pm.PropertyChangedCallback == null) ? "No" : pm.PropertyChangedCallback.Method.Name;
ReadOnly.Text = (dp.ReadOnly) ? "Yes" : "No";

pm = dp.GetMetadata(dp.OwnerType)
MetadataClass.Text = pm.GetType().Name
TypeofPropertyValue.Text = dp.PropertyType.Name
DefaultPropertyValue.Text = If((pm.DefaultValue IsNot Nothing), pm.DefaultValue.ToString(), "null")
HasCoerceValue.Text = If((pm.CoerceValueCallback Is Nothing), "No", pm.CoerceValueCallback.Method.Name)
HasPropertyChanged.Text = If((pm.PropertyChangedCallback Is Nothing), "No", pm.PropertyChangedCallback.Method.Name)
    [ReadOnly].Text = If((dp.ReadOnly), "Yes", "No")

Remarks

This property reports the type of the property's value as declared by the original property registration, through the propertyType parameter. Similar to the Name, the property type of a dependency property is immutable after registration.
