While viewing the page, you must be having the information if the current user is an admin or user. Based on this information, you will set the visibility of the control.

Use grid's RowDataBound method to set the visiblity.

VB

Protected Sub GridView_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
        Dim rtype As DataControlRowType = e.Row.RowType
        If ((rtype = DataControlRowType.DataRow)  _
                    AndAlso ((rtype <> DataControlRowType.Footer)  _
                    AndAlso ((rtype <> DataControlRowType.Separator)  _
                    AndAlso ((rtype <> DataControlRowType.Header)  _
                    AndAlso (rtype <> DataControlRowType.Pager))))) Then
            ' Get the delete button 
            ' Use Role
            ' Disable if not Admin
            If (currentRole <> "Admin") Then
                Dim btn As Button = CType(e.Row.FindControl("DeleteButton1"),Button)
                btn.Enabled = false
            End If
        End If
    End Sub

Try!
