what we can use instead of "sortkey" in vb.net

[pandu2007]

Hi All,

i am getting error while using the word "sortkey" in the following code.

Private Sub lstActTypes_Col umnClick(ByVal eventSender As System.Object, ByVal eventArgs As System.Windows. Forms.ColumnCli ckEventArgs) Handles lstActTypes.Col umnClick

Dim ColumnHeader As System.Windows. Forms.ColumnHea der = lstActTypes.Col umns(eventArgs. Column)
On Error Resume Next
lstActTypes.sor tkey = ColumnHeader.In dex - 1

End Sub

Error:'sortkey' is not a member of 'System.Windows .Forms.ListView '.
