Use the Item property to access required data values of the processed row when you handle the DataGridView.CustomUnboundColumnData event to supply data for an unbound column. The RowHandle property returns the processed row handle.
If the DataGridView.CustomUnboundColumnData event is raised when an unbound column’s value is modified in the grid (GridColumnDataEventArgs.IsSetData is true ), you can change any field’s value based on the modified value of the unbound column. To do this, specify properties of an object that the Item property returns or call the DataGridView.GetCellValue method.
Assume that the DataGridView instance is bound to a collection of orders. An order has the Product.Name, Product.UnitPrice and Quantity fields. This example shows how to add an unbound column (Total) to the grid to calculate each order amount according to the expression: UnitPrice*Quantity.
Implement logic to calculate column values in one of the following ways:
Use the GridColumn.UnboundExpression property:
Handle the DataGridView.CustomUnboundColumnData event:
