Hi Dana, 
 
Thanks for contacting Syncfusion support. 
 
You can achieve your requirement by using getSelectedRecords method of Grid which returns the currently selected records. 
 
getSelectedRecords: https://ej2.syncfusion.com/angular/documentation/api/grid/#getselectedrecords 
 




 
  btnClick(args) { 
    var selectedRecords = this.grid.getSelectedRecords(); // get the selected records detail 
    if (selectedRecords.length == 0) { 
      // if the selected record length is 0, throw the validation here. 
    } 
  } 
 
 
Note: By default, we are not supposed to use Grid control inside the form element. Because Grid component is not the input element. 
 
Please get back to us if you need further assistance with this.
