GridView未触发SelectedIndexChanged

Question

你好，我在GridView上写了这个扩展方法。一旦选定的索引被更改，我希望触发SelectedIndexChanged事件。但是，这不会发生。有什么特别的原因吗？我怎么才能把这个修好？

<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

Answer 1

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

如果Aristos是对的，则将AutoPostBack设置为True
