Hello Rob Ainscough,
Thank you writing.
RadGridView is not based on the Microsoft DataGridView. It is built on Telerik Presentation Framework which provides WPF-like visual effects and a great number of options to customize RadControls. You can find more details in our documentation
As to your second question, RadGridView can generate columns
based on the data source or can use a user defined (at design-time) columns' layout. If you follow the second scenario, the columns' layout will not be changed if you change the data source and the new data source has the same layout. In addition, you can use Save/LoadLayout
methods to save the column settings.
Do not hesitate to contact me again if you have any additional questions.
