  I want to change the value in ViewRow when View is added.
  
  I want to know how to do it.

  View viewList = (from p in _scope.GetItems()
  
  select new
  
  {
  
  p.PublisherNO,
  
  p.ISBN,
  
  p.ETC
  
  }).AsDynamic();

  viewList.Changed += ViewListChanged;

  private void ViewListChanged(object sender, C1.LiveLinq.SourceChangeEventArgs e)
  
  {
  
  if (e.ChangeType == C1.LiveLinq.SourceChangeType.Add)
  
  {
  
  // I want to set PublisherNO of ViewRow
  
  }
  
  }

  Thank you for your reply.

  private void ViewListChanged(object sender, C1.LiveLinq.SourceChangeEventArgs e)
  
  {
  
  if (e.ChangeType == C1.LiveLinq.SourceChangeType.Add)
  
  {
  
  // I want to set PublisherNO of ViewRow ???
  
  }
  
  }

  I want to know how to access ViewRow in object sender or SourceChangeEventArgs e.

  Thanks,
  
  Richard

  Hello Richard,

  Thank you for sharing further information.
  
  I have modified the sample that comes along with ComponentOne and uploaded the same and which can be downloaded using the following URL: https://www.dropbox.com/s/vnyjag37trf4etc/LiveViewsObjects_modified.zip?dl=0

  The sample contains two DataGridView, and as soon as you click on Add Row template for second grid, ViewRow’s OrderID and ShipCity are set and shown in first grid.

  Hope this helps.

  Thanks,

  Thank you for helping me solve the problem.

  View viewList = (from p in _scope.GetItems()
  
  select new
  
  {
  
  p.PublisherNO,
  
  p.ISBN,
  
  p.ETC
  
  }).AsDynamic();

  I want to change the PublisherNO using viewList.CurrentItem.
  
  I want to know how to use CurrentItem.

  Thanks,
  
  Richard

  Hello Richard,

  If our understanding for your requirement is correct then, you use anonymous type for View<>, but CurrentItem has object type, hence you want to cast object to your anonymous type.
  
  If its so, then please refer to the workaround mentioned in the following post:
