ASP.NET Kendo UI上传

Question

我想使用Kendo UI开发一个网站.我可以使用其他资格kendo-ui.但是,我无法使用ASP.NET上传文件.是否有任何示例代码或文档可以解决此问题？

Answer 1

这是使它适合我的原因:

JS:

$(document).ready(function () {
    $(".attachmentUpload").kendoUpload({
        async: {
            saveUrl: "SaveAttachment.aspx",
            autoUpload: true
        }
    });
});

页:

<input name="attachmentUpload" id="attachmentUpload" type="file" class="attachmentUpload" />

SaveAttachment.aspx.cs

public partial class SaveAttachment : Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Expires = -1;
        try
        {
            HttpPostedFile postedFile = Request.Files["attachmentUpload"];
            //do something with your postedfile
            Response.ContentType = "application/json";
            Response.Write("{}");
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());

        }
    }
}

SaveAttachment.aspx:

<%@ Page Language="C#" CodeBehind="SaveAttachment.aspx.cs" Inherits="Nstar.WebUI.Pages.SaveAttachment" EnableTheming="false" StyleSheetTheme="" Theme="" %>

它通过使用与您的方法类似的方法起作用。我创建了一个 upload.aspx 网络表单并通过以下方式调用它：

 $("#userImage").kendoUpload({
                async: {
                    saveUrl: "upload.aspx"
                }
            });

我在 upload.aspx 的 aspx.cs 文件中有这段代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;

public partial class upload : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        ProcessRequest();
    }
    public void ProcessRequest()
    {
        Response.Expires = -1;
        try
        {
            var db = new mypicksDBDataContext();
            HttpPostedFile postedFile = Request.Files["photos"];
            string savepath = Server.MapPath("userFolders/images/");
            string filename = postedFile.FileName;
            if (!Directory.Exists(savepath))
                Directory.CreateDirectory(savepath);
            postedFile.SaveAs(savepath + filename);
            Response.Write("upload");
        }
        catch (Exception ex)
        {
            Response.Write (ex.ToString());

        }
    }
}

效果很好。它上传了文件，但出现了新问题。如何将结果返回给kendoui. 它上传但始终显示错误和重试按钮。在 Kendo-ui 的文档中，它说返回空字符串以成功上传。我尝试了 Response.Write(""); 但它不起作用。
