RegisterStartupScript错误消息VB.NET

Question

我正在尝试从我的VB.NET代码中调用JavaScript代码并使用以下代码：

Protected Sub ApplyGridViewPageChangingActions(ByVal sender As Object, ByVal e As EventArgs) Handles GridView_Body.PageIndexChanged
    Dim oldPageIndex As Integer = Context.Session("GridViewPage")

    If GridView_Body.PageIndex > oldPageIndex Then
        Dim func As String = "ApplyGridViewPageChangingActions('" + Context.Session("LastFundCode") + "', '" + Context.Session("ExpOrColl") + "');"
        Context.Session("GridViewPage") = GridView_Body.PageIndex
        ScriptManager.RegisterStartupScript(Me, Me.GetType(), "ApplyGridViewPageChangingActions", func, False)
    End If
End Sub

但是我收到此错误消息：

JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: The script tag registered for type 'ASP.lsc_code_placeorders_aspx' and key 'ApplyGridViewPageChangingActions' has invalid characters outside of the script tags: ApplyGridViewPageChangingActions('baef', '0');. Only properly formatted script tags can be registered.

为什么格式不正确？ ApplyGridViewPageChangingActions（'baef'，'0'）;看起来完全可以接受。
