HasChanged Property (DataItem)

Indicates when this object needs to be written to persistent storage.

Syntax

public bool HasChanged {get; set;}

public: __property bool get_HasChanged();
public: __property void set_HasChanged( 
   bool value
);

public:
property bool HasChanged {
   bool get();
   void set (    bool value);
}

'Declaration
 
Public Property HasChanged As Boolean

'Usage
 
Dim instance As DataItem
Dim value As Boolean
 
instance.HasChanged = value
 
value = instance.HasChanged

Remarks

true if any persistent part of this object has changed; otherwise false. When FormSetFile writes this object to a form set file, or when it reads this object from a form set file, it will reset this property to false. The same is true when FormDefinitionFile reads or writes a FormDefinition that includes this object.

The persistent parts of this object are the Type and Content properties. When you change any of them, this property will automatically change to true.

You can also set the value of this property.

Default value: false
