CheckBoxSelectionModel for Grid -- how to get all selected rows on grid

Hi All,

I am new to Ext JS. First off I am using Ext JS 5. I have a grid that has a bottom toolbar which contains a button, that when clicked, should be able to access the record data of all rows selected on the grid. How do I do this?

I am not an expert JS programmer much less using Ext JS. If you can provide sample code or point me to references/links would be much appreciated. Thanks in advance.
