How to add user parameter in plugin menu

If you like to code according to different parameters in your PageEventsBase  plugin, where param1 will do task1, and param2 will do task2 then while creating menu, add an argument UserParm

Inside Plugin, code can be written like this:

public override void SetUserParm(string UserParm)
{
    /*example code to handle UserParm provided in menu*/
    if (string.IsNullOrEmpty(UserParm))
    return;
    switch (UserParm)
    {
        case "Param1":
            //do one thing
            break;
            case "Param2":
            // do another thing
            break;
    }
}
