Question

当我不使用allPages = true时，我的导出Excel工具栏效果很好。使用所有页面选项它不会引发任何错误并且什么都不做，我发现这可能是由于每个页面的延迟加载行造成的。

我经常搜索，没有发现任何问题。

<script>
     $(document).ready(function () {

                            dataSource = new kendo.data.DataSource({
                                serverPaging: true,
                                serverSorting: true,

                                    if (e.response.IsSuccess == false)

任何想法如何导出延迟加载的所有页面？

Answer 1

我发现了我的问题。它是MaxJsonLength，因为我的操作结果是new JavaScriptSerializer().Serialize(_orderList).

我通过Int32.MaxValue()

解决了这个问题

  var json = new JavaScriptSerializer();
            json.MaxJsonLength = Int32.MaxValue; 
            var jsonResult = json.Serialize(_orderList);
            return jsonResult;

KendoGrid Excel导出所有延迟加载的页面
