• • I have setup the form as follows:
    The GridView.OptionsView.NewItemRowPosition = Bottom
    The view has most of the columns from MyDataSource
    The GridControl's datasource is set to MyBindingSource
    When I click on any column of the new "empty" row at the bottom of the grid, I am allowed to edit. Unfortunately until I begin to type the BindingSource.AddingNew event is not fired.
    This is preventing me from setting some of the values on the new row until the user types.
    I tested this scenario with a standard System.Windows.Forms.DataGridView bound to the same bindingsource. As soon as I click on the new row of the DataGridView, the AddingNew event is triggered immediately. This is perfect because it allows me to setup default values and they are reflected to the user as soon as I click on the new row.
    What do I need to change in my Gridview / GridControl to get this same effect.
    Thanks

  Hi Charles,
  Thank you for the message.
  To initialize new rows, handle the GridView.InitNewRow event. However, this event is raised after an end-user starts typing in a new item row.
  So, to force the GridView.InitNewRow/BindingSource.AddingNew event to fire when an end-user clicks within the new item row, handle the GridView.ShownEditor event and set the GridView.ActiveEditor.IsModified property to true:

  [C#]

  private void gridView1_ShownEditor(object sender, EventArgs e) { 
       GridView view = sender as GridView; 
      if(view.IsNewItemRow(view.FocusedRowHandle)) 
          view.ActiveEditor.IsModified = true; 
  }

Please try this approach, and let me know your results.
Thanks,
Svetlana
