Overrides
Remarks
Call Assign to copy the properties from another object of the same type. The standard form of a call to Assign is
destination.Assign(source);
which tells the destination object to copy the contents of the source object to itself. In this method, all child objects are ignored. If you want to copy child objects, use the AssignAll(Base) method.

public override void Serialize(FRWriter writer)Parameters
| Type | Name | Description |

Overrides
Remarks
Do not call this method directly. You should override it if you are developing a new component for FastReport.
This method is called when the object needs to save the state. It may happen when:
- saving the report to the file or stream;
- saving the report to the designer's undo buffer;
- assigning the object to another object using the Assign(Base) or AssignAll(Base) methods;
- saving the object to the designer's clipboard;
- saving the object to the preview (when run a report).
