To do it in C# (VB is pretty similar)

There are a set of events in the ControllerBase you can override

Create your own ControllerBase class in your project

public class CellEvent : SourceGrid.Cells.Controllers.ControllerBase
         public override void OnFocusLeaving(SourceGrid.CellContext sender, EventArgs e)
            base.OnFocusLeaving(sender, e);

            // Do your validation here

Declare this in the grid
CellEvent eventController = new CellEvent();   

and add it to a cell
this[r, c].AddController(eventController);

From the documentation...
Here the list of events that can be used inside a Controller:
  • Mouse: OnMouseDown, OnMouseUp, OnMouseMove, OnMouseEnter, OnMouseLeave
  • Keys: OnKeyUp, OnKeyDown, OnKeyPress
  • Click: OnDoubleClick, OnClick
  • Focus: OnFocusLeaving, OnFocusLeft, OnFocusEntering, OnFocusEntered, CanReceiveFocus
  • Cell Value: OnValueChanging, OnValueChanged
  • Edit: OnEditStarting, OnEditStarted, OnEditEnded
