Register CallBack:

ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetUIController().Add\_CB\_onInviteBtnClicked(onInviteBtnClicked);

CallBack Trigger Handel :

public void onInviteBtnClicked()  
{

//my logic

}

hi,

if you start/join meeting twice, you will add this callback twice. so could you help to change your code to ensure call add callback event once, and try again.

thanks.

Dats
