當我把
<asp:FileUpload ID="FileUpload1" runat="server" class="multi" /> <br /> <asp:Button ID="btnUpload" runat="server" Text="Upload All" />更新面板一切工作正常之外，但只要我把它放回更新面板...它停止工作。
ASPX CODE
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="try.aspx.vb" Inherits="AdminPanel_try" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="../js/multi-upload/jquery-1.3.2.js" type="text/javascript"></script>
<script src="../js/multi-upload/jquery.MultiFile.js" type="text/javascript"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:FileUpload ID="FileUpload1" runat="server" class="multi" />
<br />
<asp:Button ID="btnUpload" runat="server" Text="Upload All" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnUpload" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
後面的代碼
Partial Class AdminPanel_try
Inherits System.Web.UI.Page
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click
Try
' Get the HttpFileCollection
Dim hfc As HttpFileCollection = Request.Files
For i As Integer = 0 To hfc.Count - 1
Dim hpf As HttpPostedFile = hfc(i)
If hpf.ContentLength > 0 Then
hpf.SaveAs(Server.MapPath("MyFiles") & "\" & System.IO.Path.GetFileName(hpf.FileName))
Response.Write("<b>File: </b>" & hpf.FileName & " <b>Size:</b> " & hpf.ContentLength & " <b>Type:</b> " & hpf.ContentType & " Uploaded Successfully <br/>")
End If
Next i
Catch ex As Exception
End Try
End Sub
End Class
