因为项目需要用到easyui进行显示数据，，涉及到了分页，一直弄不出来，查看网上的极多文章都是同一个版本的java，代码很多。后来无意中看到一些特殊的字眼，page,rows。后来试了结果令人兴奋啊。其实很简单，但对于我刚接触感觉有点困难。我是用.net mvc来实现的。代码如下： easyui代码： $("#diaryBackground").datagrid({ title: '日记背景列表', iconCls: 'icon-grid', url: '/DiaryBackManage/GetDiaryBackground?c=' + new Date(), striped: true, fitColumns: true, striped: true, pageNumber: 1, pageSize:10, fit: true, singleSelect: true, rownumbers: true, columns: []， }); MVC: public ActionResult GetDiaryBackground() { int pageSize = Convert.ToInt32(Request["rows"]);//通过这个获取得到pageSize int pageNum = Convert.ToInt32(Request["page"]);/

I've seen a number of examples that do this in the code behind , I want to keep the principle of MVVM and not touch the code behind, I'm looking for a way to do this in XAML . Have one? 回答1: I am assuming your TextBlock is nested within a ScrollViewer . In this case you are going to have to create an attached property.

WPF DataGrid flickering issue

问题 In WPF, I have a DataGrid bound to a DataView in the ViewModel class. It is a touch panel embedded project, so every time I touch and slide my fingers on the panel it keeps sending me values and saves those values to the DataTable and assigns it to the bound DataView in a way where it can show only 5 or 10 rows (predefined) as the data gets updated. Every time I get a new row I delete the last until the total DataTable row count is 5/10. The issue here is that it is taking longer than usual
