:이 코드입니다. GmapControl을 마우스 오른쪽 버튼으로 클릭 한 다음 속성을 선택할 수 있습니다. 그런 다음 조명 버튼을 클릭하면 이벤트 목록이 표시되고 OnMarkerClick 이벤트가 두 번 클릭하면 이벤트 처리기가 작성되거나 그렇게 설정할 수 있습니다.

gMapControl1.OnMarkerClick += (marker, mouseArgs) => 
{ 
    // From this point marker is the clicked marker do as you wish here 
    // Pass it to another form and use form.show to display the form. 
    // MessageBox.Show is to show proof the event fired. 
    MessageBox.Show(marker.ToolTipText); 
    // If you have a marker form you can display it like so. 
    MarkerForm form = new MarkerForm(); 
    form.Show(); 
};
