Sorting Problem for GridHyperLinkColumn

[anna]

I have a radgrid with multiple cols. how do I apply sorting only on my first column that is a GridHyperLinkColumn?
I tried:

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As GridColumnCreatedEventArgs)

If TypeOf e.Column Is GridHyperLinkColumn Then

Dim col As GridHyperLinkColumn = DirectCast(e.Column, GridHyperLinkColumn)

If col.UniqueName = "column1" Then

col.Allowsorting =

True ' this line gives error.' Allowsorting  is not allowed for GridHyperLinkColumn

End If

End If

End Sub
