System.Data Namespace Constraint Class
Returns the collection of user-defined Constraint properties.
| Script |
[ PropertyCollection variable = ] Constraint.ExtendedProperties |
The property is read only with no default value.
The ExtendedProperties property allows you to store custom information for a Constraint. For example, you might store a time when the data should be refreshed.
Extended properties must be of type String. Properties that are not of type String are not persisted when the Constraint is written as XML.
The following example adds a custom property to the PropertyCollection returned by the ExtendedProperties property. The second example retrieves the custom property.
private void SetProperty ( Constraint myConstraint ) {
myConstraint.ExtendedProperties.Add ( "password", "yervzeñun" );
}
private void GetProperty ( Constraint myConstraint ) {
Response.Write ( myConstraint.ExtendedProperties [ "password" ].ToString ( ) );
}
Private Sub SetProperty ( myConstraint As Constraint )
myConstraint.ExtendedProperties.Add ( "password", "yervzeñun" )
End Sub
Private Sub GetProperty ( myConstraint As Constraint )
Response.Write ( myConstraint.ExtendedProperties ( "password" ).ToString ( ) )
End Sub |
