Id Property (PropertyValue)

In This Topic

Returns the P8 property descriptor (id and index) that the object points to. To use the Id property, the PropertyValue object must point to a project property (persistent property). Transient PropertyValue objects don't have descriptors because they point directly to a value. A transient PropertyValue is created by operator and takes values of base types.

Syntax

C#
C++/CLI

public AnyPropertyId Id {get;}

public:
property AnyPropertyId^ Id {
   AnyPropertyId^ get();
}

Exceptions

Exception	Description
System.InvalidOperationException	Thrown when object is in transient mode (in other words, when the object is not pointed to a PropertyList).

Example

Function function = page.Functions[0]; // A valid Function object

PropertyValue propertyValue1 = "123"; // Transient object
PropertyValue propertyValue2 = 12; // Also transient object

PropertyValue propertyValue3 = function.Properties.FUNC_ARTICLE_PARTNR;

AnyPropertyId propertyId3 = new AnyPropertyId (myProject.Project, "20100");

Assert.AreEqual(propertyValue3.Id.AsInt, propertyId3.AsInt);
Assert.AreEqual(propertyValue3.Id.Index, 0); // In this case, where the index was not specified, PropertyValue3.Id.Index is 0.

PropertyValue propertyValue4 = function.Properties.FUNC_ARTICLE_PARTNR[12];

AnyPropertyId propertyId4 = new AnyPropertyId (myProject.Project, "20100");
propertyId4.Index = 12;

int propertyId = propertyValue4.Id.AsInt;
int propertyIndex = propertyValue4.Id.Index;

Assert.AreEqual(propertyValue4.Id.AsInt, propertyId4.AsInt);
