How to validate cell edits in the table?

Listen to this event:

this.ganttControl.TemplateApplied += new EventHandler(

delegate(object sender, EventArgs e)

{

// GanttTable is non-null only after the TemplateApplied event is fired

this.ganttControl.GanttTable.CellEditEnding +=new EventHandler<DataGridCellEditEndingEventArgs>(GanttTable_CellEditEnding);

}

...whose handler will be fired before a cell edit ends where you could perform validation on the edited cell.
