ConstraintCollection.RemoveAt Method

System.Data Namespace ConstraintCollection Class

Removes the constraint at the specified index from the collection.

[ VB ]
Public Sub RemoveAt ( _
   ByVal index As Integer _
)

[ C# ]
public void RemoveAt (
   int index
);

[ C++ ]
public: void RemoveAt (
   int index
);

[ JScript ]
public function RemoveAt (
   index : int
);

index: The index of the Constraint to remove.

Exception Type	Condition
IndexOutOfRangeException	Occurs when the collection does not have a constraint at this index.

The IndexOf method returns the index of a given Constraint.

Use the Contains method to determine if the collection contains the target Constraint.

Use the CanRemove method to determine if a Constraint can be removed.the CollectionChanged event occurs if the removal succeeds.

The following example uses the IndexOf method in conjunction with the RemoveAt method to remove a constraint from the ConstraintCollection.

private void RemoveConstraint ( ConstraintCollection myConstraints, 
      Constraint myConstraint ) {
   try {
      if ( myConstraints.Contains ( myConstraint.ConstraintName ) ) {
         if ( myConstraints.CanRemove ( myConstraint ) ) {
            myConstraints.RemoveAt (
               myConstraints.IndexOf ( myConstraint.ConstraintName ) );
         }
      }
   }
   catch ( Exception myException ) {
      Response.Write ( myException.Message );
   }
}

Private Sub RemoveConstraint _
      ( myConstraints As ConstraintCollection, myConstraint As Constraint )
   Try
      If myConstraints.Contains ( myConstraint.ConstraintName ) Then
         If myConstraints.CanRemove ( myConstraint ) Then
            myConstraints.RemoveAt _
               ( myConstraints.IndexOf ( myConstraint.ConstraintName ) )
         End If
      End If

   Catch myException As Exception
      Response.Write ( myException.Message )
   End Try
End Sub
