U9C UI价格重算

有时可能遇到需要在UI界面按钮执行之前改数据的问题，这时就需要通过UI插件的方式实现。

比如标准采购更改最终价的问题，额外需要在加一些费用。

实际案例，标准采购价格需要加上额外费用，额外费用维护在货源表字段字段中

前提参考UI插件

    if (webButton != null && webButton.Action == "SaveClick")
    {
        CalcPrice(Part);
    }

    base.BeforeEventProcess(Part, eventName, sender, args, out executeDefault);
}
