进销存项目总结

由 谁说我不能喝 提交于 2019-12-27 02:22:18
最近我们项目组4个人，后端3人，前端一人，做了一个简易进销存管理系统，为期时长2个月时间，刚刚做完，现在做个总结 项目中主要是卖的是产品是移动硬盘，系统取名盘源，我主要复制基础模块和采购订单模块 采购订单模块 ：主要要注意采购订单和采购订单明细，两者作为组合关系也就是强聚合关系，不能单独存在，所以在配置domain的时候，相应一对多和多对一，强级联和孤儿删除，一方放弃关系维护，都得注意。 基础domain肯定配置： 数据字典类型，数据字典明细，供应商，产品。 采购订单分析： 每个字段的含义 这个字段从哪里来？ 这个字段是否可以为null 然后就是后端相应Repository，service，servicimpl，controller配置 前端 前端显示注意点就是供应商，采购员，状态都是外键，所以我们得对其进行格式化才能正常显示，还有就是交易时间，不管是从前端传到后端，还是从后端传到前端，时间都得进行格式化 在进行数据添加时候，我们需要把订单和订单明细显示一张表单上，这里需要在form表单中插入datagrid。小计通过输入数量，价格自动计算值，总金额和总数量通过输入数量，和小计累算出来 在修改进行数据回显得时候，form表单数据回显，datagrid中数据并不会回显，需要调用datagrid中loaddata方法进行数据回显 然后删除功能实现，把订单中关联对象除掉，这样就可以n

关于C# wpf DataGrid单元格双击设置单元格内容

由 强颜欢笑 提交于 2019-12-26 15:34:48
1、我是使用了 visual stadio 2015, 用的C# WPF写个工具，但是发现wpf原生没有涉及表格的东西（类似 winform·的DataGridView）,所以使用的是toolkit工具类中的DataGrid,作为表表格展现。 2、本意是做个单元格实现双击则单元格的内容在“自动”和”“ 间切换，但是发现使用DataGrid的MouseDoubleClick事件时发现当鼠标双击整个DataGrid的任何地方都会触发双击事件，因此要判断当前双击的位置，顾查询了很多资料（TOOLkit的资料忒少了。msdn上关于DataGrid的无法区分是否适用于该DataGrid）。 3、这是我的源代码片段，其中this.dataGrid_YHDZ_YHDZD是我的DataGrid名字。 private void dataGrid_YHDZ_YHDZD_MouseDoubleClick(object sender, MouseButtonEventArgs e) { Point aP = e.GetPosition(this.dataGrid_YHDZ_YHDZD); IInputElement obj = this.dataGrid_YHDZ_YHDZD.InputHitTest(aP); DependencyObject target = obj as
