Using IsDirty

Defining an IsDirty property will the application to only save objects that have changes. This can increase performance when there are a large number of objects to save. If there is an IsDirty property and it is true OR if there is no IsDirty property, then the object will be updated.

//Get the current instance of the helper

IDataHelper db = DataHelper.SessionFactory();

Order order = new Order

{

Notes = "Initial notes"

};

// New record is inserted

db.Save(order);

Order testOrder = db.LoadByPrimaryKey<Order>(order.OrderId);

// Change a property

order.Notes = "Updated notes";

order.IsDirty = false;

// Save operation is ignored because IsDirty is false

db.Save(order);

// Make it dirty

order.IsDirty = true;

// Save updated record

db.Save(order);

testOrderDetail = db.LoadByPrimaryKey<Order>(order.OrderId);
