  Hi All ,

  I have 2 buttons for doing undo and redo operations on spreadsheet. On click of these buttons I am invoking the below code

  
  var undoManager = new GC.Spread.Commands.UndoManager();
  function undo(){
  	if(undoManager)
  	undoManager.undo();
  }
  function redo(){
  	if(undoManager)
  	undoManager.redo();
  }
  
  $('#undo').click(function(){
  undo();
  });
  $('#redo').click(function(){
  redo();
  })
  
  

  But this code is not working. When I click on undo or redo nothing is happening.

  Hi,

  You need to use the UndoManager for the Workbook. Please refer to the following code snippet:

  var spreadInstance = new GC.Spread.Sheets.Workbook(document.getElementById('ss'));
  var undoManager = spreadInstance.undoManager();
  
  function undo(){
      if(undoManager)
          undoManager.undo();
  }
  function redo(){
      if(undoManager)
          undoManager.redo();
  }
  
  $('#undo').click(function(){
      undo();
  });
  $('#redo').click(function(){
      redo();
  });
  

  Regards
