Visual Basic
C#

'Declaration
 
Public Function IsColumnBound( _
   ByVal column As System.Integer _
) As System.Boolean

'Usage
 
Dim instance As Worksheet
Dim column As System.Integer
Dim value As System.Boolean
 
value = instance.IsColumnBound(column)

public System.bool IsColumnBound( 
   System.int column
)

Parameters

column: The column index.

Return Value

true if the column is bound; otherwise, false.

This example uses the IsColumnBound method.
