Hi @Nitin Batra,

Without a more specific description or even an image, I can't totally help you with what you want exactly, but you can use these selectors on your App's CSS Theme, to manipulate the checkboxes styles:

// Base styles

.datagrid-container [type='checkbox']:not(.checkbox) {

   appearance: none /* use this to reset html native styles*/

}

// Selected styles

.datagrid-container [type='checkbox']:not(.checkbox):checked{}

Here's a very simple and ugly example:
