Hi Bhanu, nice to see you need this requirement too. I created this example as response to a question on this forum a couple of weeks ago.
Atlas3Extra is not a project to download the mpr-file for, but rather you can download the module ‘Atlas3Extras’ from the marketplace into your application. Then add either class ‘selectionradiobutton’ or ‘selectioncheckbox’ to the datagrid.
If you like that module, please give it a nice rating. Much appreciated. If you have any UI-styles your to add, please let me know and I will tell you how you can add them.
