WPF DataGrid flickering issue

半腔热情 提交于 2020-02-22 04:02:07
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

Reapter 添加删除按钮

淺唱寂寞╮ 提交于 2020-02-07 06:21:50
repeater中的删除按钮和datagrid下的删除在实现上,还是有一定的区别的,由于repeater在客户端生成的html代码是非常干净的,所以特别受到众多web2.0网站的欢迎(不像datagrid生成的table),但是由于repeater集成了较少的功能,高可定制化,也带来了开发的难度。比如如果在datagrid下面要删除一行数据,那么仅仅是一个linkbutton,然后在datagrid delete command事件中编写删除代码再重新绑定来实现,但是在repeater中,却不能那样做,因为你几乎没有办法再那个事件中定位是哪行触发的删除事件。 方法一 采用的一个QueryString传参数的办法,在前台绑定的时候,采用如下代码: <td align="center" class="Login2"><a href =User.aspx?Delid=<%#Eval("id")%>>删除</a></td> 后台page_load()代码如下: protected void Page_Load(object sender, EventArgs e) { //注意数据绑定 DelItemByid(); } protected void DelItemByid() { if (Request.QueryString["Delid"] != null) {

表里的数据是通过 Servlet 调用 DAO 从数据库里获得,再通过 GSON 架包转成 JSON 字符串 在页面上直接请求该 Servlet 既可以获得数据并放入 DataGrid 中 注意:这里的 field 中的值就是 Json 字符串的 key 的值。 来源: CSDN 作者: 爱妮三千遍 链接: https://blog.csdn.net/ketouch/article/details/104167714

问题 I tried to understand but failed. In WinForms I can build up some rows in a datagridview. By using Application.DoEvents (not nice but works) I can see how it is building up also when the list is very huge. I just want some similar in WPF.

WPF Datagrid - adding and deleting rows and MVVM

橙三吉。 提交于 2020-02-04 01:30:14
问题 If my DataGrid is bound to an MVVM property and the user deletes or adds a row to the grid, shouldn't it automatically add or delete the data from the ObservableCollection tied to it? Do I have to do a command for this to work? Does it not just work with just binding to the collection? XAML <ExtendedGridControl:ExtendedDataGrid Grid.Row="5" Height="200" VerticalAlignment="Top" Grid.ColumnSpan="6" Margin="5,4,5,0" ItemsSource="{Binding InvoiceDetailsForSelectedJobInvoice, Mode=TwoWay}"
