搜索&在MVC中使用AJAX分页进行排序 [英] Searching & sorting with AJAX pagination in MVC

问题描述

我正在使用搜索，分页和排序开发MVC4应用程序。普通视图下一切正常。

现在我使用Ajax&转换同样的应用程序局部视图。

如何通过我的搜索&通过驻留在部分View上的Paging控件对参数进行排序。现在，我能够在部分视图中加载过滤后的数据，但移动到下一页，丢失了我的搜索参数并加载了忽略搜索过滤器的所有记录。



_PartialView.cshtml中的我的分页控件

I am developing MVC4 application with Searching, Paging and Sorting. Everything works fine with normal view.
Now I am converting same application using Ajax & Partial View.
How can I pass my search & sort parameter through Paging control residing on partial View. Now, I am able to load filtered data in partial view but moving to next page, lost my search parameters and loads all records ignoring search filters.

My Paging Control in _PartialView.cshtml

@Html.PagedListPager(Model,
                        page => Url.Action("AjaxMethod", 
                            new 
                            {  
                                page,
                                searchByUserName = Request.QueryString["searchByUserName"],
                                searchByReaderName = Request.QueryString["searchByReaderName"],
                                searchByReaderType = Request.QueryString["searchByReaderType"],
                                searchByUploadDate = Request.QueryString["searchByUploadDate"],
                                sortBy = Request.QueryString["sortBy"]
                            }), 
                        //new PagedListRenderOptions.() { Display = PagedListDisplayMode.IfNeeded, DisplayPageCountAndCurrentLocation = true }
                        PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing( new AjaxOptions(){ HttpMethod = "GET", UpdateTargetId = "divData"})
                        )

请建议，我缺少什么。

推荐答案

Hello Guys，

我开始知道自己错过了什么，部分视图没有得到Request.QueryString值，这就是分页控制丢失搜索参数并加载所有记录的原因。所以我在_PartialView.cshtml中修改了Pager控件，如下所示：

Hello Guys,
I came to know what I m missing, Partial View doesn't got Request.QueryString values thats why paging control lost search parameters and loads all records. So I modified Pager control in _PartialView.cshtml as follows :

@Html.PagedListPager(Model,
                        page => Url.Action("AjaxMethod",
                            new
                            {
                                page,
                                searchByUserName = ViewBag.searchByUserName, // Request.QueryString["searchByUserName"],
                                searchByReaderName = ViewBag.searchByReaderName, // Request.QueryString["searchByReaderName"],
                                searchByReaderType = ViewBag.searchByReaderType, // Request.QueryString["searchByReaderType"],
                                searchByUploadDate = ViewBag.searchByUploadDate, // Request.QueryString["searchByUploadDate"],
                                sortBy = ViewBag.sortBy // Request.QueryString["sortBy"]
                            }),                        
                        PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing(new AjaxOptions() 
                        { HttpMethod = "GET", UpdateTargetId = "divData", LoadingElementId="divloading" })
                        )

这些ViewBag对象在控制器操作方法中初始化。



任何人都有比这更好的解决方案以上问题。请建议。

These ViewBag objects initialized in controllers action method.

Anyone having better solution than this for the above problem. Please suggest.
