GridView没有触发SelectedIndexChanged

Question

您好我已经在GridView上编写了这个扩展方法。一旦选定的索引被更改，我想要触发SelectedIndexChanged事件。但是，它没有发生。任何特殊原因？ 我怎样才能解决这个问题？

<Extension()>
       Public Sub SelectRowByCallId(ByVal gridviewObj As GridView, ByVal callId As String)
        Dim selectedIndex As Int32 = 0
        Dim pageIndex As Int32 = 0
        Dim gridViewPages As Int32 = gridviewObj.PageCount

        For index = 0 To gridViewPages
            gridviewObj.PageIndex = index
            gridviewObj.DataBind()

            For i = 0 To gridviewObj.DataKeys.Count - 1
                If (Convert.ToString(gridviewObj.DataKeys(i).Value) = callId) Then
                    selectedIndex = i
                    pageIndex = index
                    Exit For
                End If

            Next i

        Next index

        gridviewObj.PageIndex = pageIndex
        gridviewObj.SelectedIndex = selectedIndex
        gridviewObj.DataBind()


    End Sub

如果Aristos是对的话 将AutoPostBack设置为True

设置SelectedIndex属性不会触发事件，但调用SelectRow方法会。
