Copies the contents of another, similar object.

Declaration
public override void Assign(Base source)
Parameters
Type Name Description
Base source

Source object to copy the contents from.
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 method.

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 methods;
  • saving the object to the designer's clipboard;
  • saving the object to the preview (when run a report).
