Hi Ali,  

Thanks for contacting Syncfusion support.  

Query: “I want to disable the add button when the number of records is greater than zero” 

As per your requirement we have disabled the Add toolbar item using dataBound event and actionComplete event of Grid. Refer the below code example. 

let grid: Grid = new Grid( 
        { 
            dataSource: [], 
            editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Normal', newRowPosition: 'Top' }, 
            allowPaging: true, 
            dataBound: function(args){ 
              if(grid.getCurrentViewRecords().length > 0)// to disbale the add toolbar during intial rendering  
              grid.toolbarModule.enableItems(["Grid_add"],false); 
            }, 
            actionComplete: function(args){ 
              if(args.requestType == "save"){// to disbale the toolbar when a record is added 
                setTimeout(function(args){ 
                    grid.toolbarModule.enableItems(["Grid_add"],false); 
                }.bind(grid),0) 
              } 
            }, 
            pageSettings: { pageCount: 5 }, 
…………………………. 
        }); 
    grid.appendTo('#Grid'); 

For your convenience we have prepared sample which can be referred below
