How to Raise my Custom Event Handler
-
Hi i maked a custom event as 'MouseMoveExEventArgs' that inherited from MouseEventArgs to add some more property and info as follow :
namespace CustomEventHandler { public delegate void MouseMoveExEvent(object sender, MouseMoveExEventArgs e); public class MouseMoveExEventArgs : System.Windows.Forms.MouseEventArgs { Point m_mapScrollPos; public MouseMoveExEventArgs(Point mapScrollPosition) : base(System.Windows.Forms.MouseButtons.Left,1,mapScrollPosition.X,mapScrollPosition.Y,0) { this.m_mapScrollPos = mapScrollPosition; } public Point MapScrollPosition { get { return this.m_mapScrollPos; } } } }and in my custom user control, write this code :public event MouseMoveExEvent MouseMoveEx; . . . protected virtual void OnMouseMoveEx(MouseMoveExEventArgs e) { if (MouseMoveEx != null) { MouseMoveEx(this, e); } }but i don't know how to raise this event, when mouse move on my control (like MouseMove event), for this work, i call OnMouseMoveEx event handler in OnMouseMove event handler as follow :protected override void OnMouseMove(MouseEventArgs e) { Point p = new Point(e.X, e.Y); OnMouseMoveEx(new MouseMoveExEventArgs(p)); }my purpose is that replace orginal MouseEventArgs class with MouseMoveExEventArgs event handler in MouseMove event and raise it when Mousemove event fire. thanks -

I think, you will get how to do it. Regards, Amar

thanks when in designer mode, double click on MouseMoveEx event in events window, it will be genererated automatically :
customcontrol1.MouseMoveEx+=OnMouseMoveEx;but i think that the event handler doesn't know what time fire this event.Hi, Can you describe your coding flow shortly ? Eg. class customcontrol { //code of event handler } class where_you_use_customcontrol { //code of event handler } and when you want to raise that event. So my view become clear. Regards, Amar
