MouseLeftButtonUp的事件里怎样调用其他事件

[KeepDream]

public delegate void appoint(object sender, AppointmentCreatingEventArgs e);
public event appoint Comming;
public void create(object sender, AppointmentCreatingEventArgs e)
{
if (Comming != null)
{
Comming(sender, e);
}

}
void MainPage_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
isMouseDown = false;
((UIElement)sender).ReleaseMouseCapture();
Comming += new appoint(scheduler_AppointmentCreating);



}
void scheduler_AppointmentCreating(object sender, AppointmentCreatingEventArgs e)
{
MessageBox.Show("asdsad");
SessionAppointment sess = new SessionAppointment();
// sess.Copy();
sess.Subject = "我的Demo ";
sess.Body = "The Entity Framework combined with the Entity Data Model (EDM) bring data access to a new level in Enterprise Applications. Entity Framework Object Services APIs, while providing a lot of automated functionality, are filled with features that give developers much more control over how objects are handled. The most important jobs of the ObjectContext are relationship management and change tracking. This session drills into how the ObjectContext manages relationships and how you can control its behavior. This is especially important in SOA scenarios where you may need to transport ObjectGraphs. We also look closely at change tracking, focusing on the challenges and solutions for dealing with data concurrency when moving objects across tiers in your enterprise applications. Knowing what to expect from these features and how to take control of them will empower you in your use of the Entity Framework and EDMs in your Web sites, SOA applications, and smart clients, as well as other applications that share the EDM.";
sess.SessionRoom = "406";
sess.Speaker = "Shoun Petrik";
sess.Level = 400;
IAppointment other = sess;
//sess.CopyFrom(other);
e.NewAppointment = sess;
}
我想在MouseLeftButtonUp事件调用 scheduler_AppointmentCreating这个事件 用委托也不行..两个事件源不一样啊..怎么办？？大鸟们 帮看下 小弟谢了

按照你的写法，只有在触发了 MainPage_MouseLeftButtonUp事件后，然后再执行create方法，才能触发scheduler_AppointmentCreating事件，MainPage_MouseLeftButtonUp事件里只是注册了事件处理方法（以保证在Create方法中能执行），并不会执行事件处理方法

[KeepDream]

MainPage_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
scheduler_AppointmentCreating(object sender, AppointmentCreatingEventArgs e)
两个的e不同啊..不能调用啊

在你代码中并没有看到这2个e有什么直接关系……委托跟sender和EventArgs都没有关系的，是不是你对委托的理解有偏差？

[沝林]

scheduler_AppointmentCreating事件的sender和EventArgs只跟create方法传入的sender和EventArgs有关，也就是说只有调用create(obj,new AppointmentCreatingEventArgs(...))才会触发scheduler_AppointmentCreating事件，跟MainPage_MouseLeftButtonUp的EventArgs没有关系

[KeepDream]

不适用委托能调用吗 可以给出代码吗？谢谢咯

[沝林]

create方法调用在什么地方？根据你贴的代码还看不出来你要实现什么功能？

我们用的是第三方控件，控件本身是
void scheduler_AppointmentCreating(object sender, AppointmentCreatingEventArgs e)
这个事件创建一个新实力，但是我们需求是 鼠标将一个Image拖过去，创建实例，所以我在鼠标的
MainPage_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
这是事件来调用它本身的事件啊。
也就是说 鼠标将图片拖到第三方控件上 要调用它的事件来操作..

首先你要知道的是：事件不是方法，不能直接调用，事件是一种特殊的委托，也是对方法的引用;
另外AppointmentCreating是在Appointment创建时触发的事件，scheduler_AppointmentCreating是事件处理方法，并不是scheduler_AppointmentCreating创建实例
