Question

我正在为我们的CRM系统构建一个自定义的插件。当最终用户满足特定条件时，我只想弹出一个消息框。我不确定我是否在以下实施中做得正确：

我在全局范围内声明了一个触发变量：

public class MyWorkspaceAddIn : Panel, IWorkspaceComponent2
    {

        private bool _readOnly;
        private IRecordContext _recordContext;
        private IGlobalContext _globalContext;
        private bool _triggerPopup = true;

以下类中的弹出代码：

 void _incident_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
        {//check property and/or i.Prod and then show the popup

           // MessageBox.Show(e.PropertyName); //Check what property name is

            if (_incident.ProductID == 182 && _triggerPopup) //If product ID is 183 in incident 
            {
                MessageBox.Show("The GO Classic will soon be end of life, make sure you propose the customer to buy a new device and offer maximum 20% discount to reward his/her loyalty (NOTE: refurbished devices are not included in this offer).");
                _triggerPopup = false; //Do not pop up
            }

我希望消息框只会弹出一次。

Answer 1

这看起来很不错，但你也可以做的只是在PropertyChanged上实现你自己的事件，例如，它会触发一次。 PropertyFirstChanged然后您将避免额外的代码调用。

Answer 2

你的代码对我来说似乎是正确的，如果你的代码是正确的，那么除此之外还有一个特定的问题吗？

请注意，它将显示MyWorkspaceAddIn的每个实例的弹出窗口。如果您希望弹出窗口仅显示应用程序生命周期一次，则应在另一个类中调用静态变量。

仅显示一次消息
