Visual Basic: RDO Data Control
Required Property
See Also Example Applies To
Returns a value that indicates whether an rdoColumn requires a non-Null value.
Syntax
object**.Required**
The object placeholder represents an object expression that evaluates to an object in the Applies To list.
Return Values
The return values for the Required property are:
| Value | Description |
| True | A Null value isn't allowed. |
| False | A Null value is allowed. |
Remarks
For an rdoColumn object, you can use the Required property along with the AllowZeroLength property to determine the validity of the Value property setting for that rdoColumn object. If Required is set to False, the column can contain Null values as well as values that meet the conditions specified by the AllowZeroLength property setting.
