#Remarks
The BootstrapBinaryImage control can be used to display on the web page any valid image (supported by the requesting browser) taken from a binary stream.
This class inherits its basic functionality from its ancestor. The ASPxBinaryImage.ContentBytes property provides access to the editor’s contents represented by an array of bytes. The ASPxBinaryImage.StoreContentBytesInViewState property allows you to control whether the editor’s content should be stored within the editor’s view state between postbacks.
