With the introduction of a completely new calculation engine, enhanced user interface, newly integrated styles and optimized import and export capabilities; Spread for WinForms 12 exhibits high performance with faster data access and low memory footprint, as compared to Spread for WinForms 10.
Hence, it is highly recommended to get rid of obsolete APIs and upgrade your code with new APIs that will not just deliver high run-time performance but will also enable you to achieve considerably greater amount of efficiency and increased competency in terms of saving time, efforts and resources.
The following table lists the obsolete API (classes and interfaces along with their corresponding obsolete properties, methods, events and constructors) from versions prior to Spread for WinForms 12 that are supported for backwards compatibility in this version of the product, but might not be supported in future versions. Please review your existing projects and update them according to the options described in the table.
