獲取文本框的文本在UpdatePanel外

Question

<asp:TextBox ID="TextBox1" runat="server" Height="30px" Width="700px" placeholder="Enter Title" ></asp:TextBox> 
    <asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
      <ContentTemplate> 

          <asp:AjaxFileUpload ID="AjaxUploadImages" runat="server" AllowedFileTypes="jpg,jpeg,png,gif" 
           onuploadcomplete="AjaxUploadImages_UploadComplete"/> 

      </ContentTemplate> 
     </asp:UpdatePanel> 

我想TextBox1的文本上OnUploadComplete事件像這個 -

protected void AjaxUploadImages_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) 
    { 
     string path = Server.MapPath("~/images/") + e.FileName; 
     AjaxUploadImages.SaveAs(path); 
     string content = TextBox1.Text.ToString(); 
    } 

Answer 1

protected void AjaxUploadImages_UploadComplete(object sender,AjaxControlToolkit.AjaxFileUploadEventArgs e) 
    { 
     string path = Server.MapPath("~/images/") + e.FileName; 
     AjaxUploadImages.SaveAs(path); 
     string content = TextBox1.Text.ToString(); 
    }
