End Sub
Remarks
This method is called when the user presses ALT+0 to allow a column to enter the appropriate null value. For example, when called on a DataGridTextBoxColumn, the appropriate NullText value is inserted into the column.
The EnterNullValue has no default behavior. When inheriting from DataGridColumnStyle, override the method to enter null in a column.
