Example

This example subclasses the IEditor class and uses a check box as the cell editor to illustrate the use of the methods and events.

public static CheckBox ck = new CheckBox();

class myEditor : FarPoint.Win.Spread.CellType.IEditor
{
     public event EventHandler EditingCanceled;
     public event EventHandler EditingStopped;
     public bool StopEditing()
     {
          if (EditingStopped != null)
          {
               EditingStopped(ck, EventArgs.Empty);
               base.FireEditingStopped();
               return true;
          }
          else
          {
               return false;
          }
     }

     public void CancelEditing()
     {
          EditingCanceled(ck, EventArgs.Empty);
          base.FireEditingCanceled();
     }
     
     public bool IsReservedKey(KeyEventArgs e)
     {
          return false;
     }
          
     public bool IsValid(Object value)
     {
          return true;
     }
     
     public Size GetPreferredSize(System.Windows.Forms.Control editor)
     {
          return editor.Size;
     }

     public Cursor GetReservedCursor(object o)
     {
          return null;
     }

     public Control GetEditorControl(FarPoint.Win.Spread.Appearance appr, float zoom)
     {
          return ck;
     }

     public object GetEditorValue()
     {
          return ck.CheckState;
     }

     public void SetEditorValue(object value)
     {
     }

     public object IsReservedLocation(Graphics g, int x, int y, Rectangle r, FarPoint.Win.Spread.Appearance appr, object value,
float zoom)
     {
          return null;
     }

     public void StartEditing(EventArgs e, bool selectAll)
     {
          selectAll = true;
     }

     public void ShowSubEditor()
     {
     this.ShowSubEditor();
     }
}

private void Form1_Load(object sender, System.EventArgs e)
{
     fpSpread1.ActiveSheet.Cells[0, 0].Editor = new myEditor();
}
