|---|---|
| ArgumentException | The column does not belong to the table. |
| ArgumentNullException | The column argument contains null. |
| VersionNotFoundException | The row does not have this version of data. |
The version should not be confused with the RowState property. The version argument describes the state of the data that is contained by the column relative to the column's original value.
When you set the property, an exception is generated if an exception occurs in the ColumnChanging event.
If this is an immediate edit, see EndEdit for the exceptions that can be generated.
