Thank You For your time,

but not working properly

var view            = apex.region("FLG").widget().interactiveGrid("getViews","grid");var model           = view.model;
var selectedRecords = view.getSelectedRecords();
model.forEach(function(record,index, id) { 
      var meta = model.getRecordMetadata( id );
      if (selectedRecords.includes(record)){
		   model.setValue( record, "REV_FLAG",model.getValue( record, "REV_FLAG" ))
	   }
	   else{
		   if ( meta.updated ) {
			   if ( model.canRevertRecord( record ) ) {
				   model.revertRecords( [record] );
			   }
		   }    
      }
}
);

this one works but record remains same for only last selected record.

Thank You Vinish....Thank You So much.....

I Want to change the width of some specific column in my interactive grid.Because data for that field is too long and whole grid is not visible so everty time user has to scroll left and right which is not comfortable for user i found one css  as shown below

.a-GV-table td, .a-GV-headerLabel {
white-space: normal;
}

This works ok but the checkbox called APEX$ROW_SELECTOR size doesnot change
