Question

我有一个ASP页面，其中有一个文件上传器。此文件上传器具有一个必需的字段验证器。当我选择所需的文件进行上传时，文件将成功上传，并显示一个信息框，其中包含一条成功消息。

当我单击信息框上的“确定”以使其消失时，它将尝试再次验证整个页面，并且信息框不会消失。

我尝试将文件上传器上的CausesValidation属性设置为false，但是没有运气。我也尝试过AutoPostBack和IsPostBack。

aspx代码

<%@ Page Title="Excel File Content Upload" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master"
         CodeBehind="ExcelFileContentUpload.aspx.vb" Inherits="Company.Applications.ProductionEngine.UI.ExcelFileContentUpload" %>

        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Content>

页面加载

#Region "PAGE LOAD"
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        'Load years and months into their respective dropdown lists
        If Not Page.IsPostBack Then
            Dim _currentYear As Integer = DateTime.Now.Year
            Dim _previousYear As Integer = DateTime.Now.Year - 1
            Dim _month = CultureInfo.CreateSpecificCulture("en").DateTimeFormat.MonthNames

            For i As Integer = 0 To _month.Length - 1
                ddlMonth.Items.Add(New ListItem(_month(i), i + 1).ToString())
            Next

            ddlYear.Items.Add(_currentYear)
            ddlYear.Items.Add(_previousYear)
        End If

    End Sub
#End Region
