RAD Studio VCL Reference
TComponent.ValidateContainer Method

Determines whether an object can be inserted into a container.

procedure ValidateContainer(AComponent: TComponent); dynamic;
__fastcall ValidateContainer(TComponent * AComponent);

ValidateContainer is called by a component when it is about to be inserted into a container object. By default, ValidateContainer calls the ValidateInsert method of the component specified by the AComponent parameter.  

Descendant components can override ValidateContainer to disallow a component from being inserted into specific containers. To disallow an insertion, raise an exception in the derived method.
