Esempi in C# (CSharp) per Breeze.ContextProvider ContextProvider.BeforeSaveEntity

BeforeSaveEntity() protected method

The method is called for each entity to be saved before the save occurs. If this method returns 'false' then the entity will be excluded from the save. The base implementation returns the result of BeforeSaveEntityDelegate, or 'true' if BeforeSaveEntityDelegate is null.

protected BeforeSaveEntity ( EntityInfo entityInfo ) : bool
entityInfo	EntityInfo
return	bool
