Remarks

By default, the content of the cell in the first visible row whose parent column is the main column will be displayed, using the same template defined by the column's CellContentTemplate property.

Example
All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.
The following example demonstrates how to display a scroll tip whose content and location have been modified. The flagConverter resource represents a converter that is used to return the appropriate BitmapImage according to the value of the ShipCountry cell.
