GetKey Method (DefaultSheetDataModel)

Visual Basic
C#

'Declaration
 
Public Function GetKey( _
   ByVal index As Integer _
) As Object

'Usage
 
Dim instance As DefaultSheetDataModel
Dim index As Integer
Dim value As Object
 
value = instance.GetKey(index)

public object GetKey( 
   int index
)

Parameters

index: If UseRowIndex is true, this is the row index; otherwise, this is the column index

Return Value

Object associated with this row or column as its key

If the UseRowIndex property is set to true, the method generates a key for the specified row. Otherwise, the GetKey method generates a key for the specified column.

This example calls the GetKey method to return the key for the first row.
