Question

I have a ASP.NET page that contains both javascript and ASP.NET user controls. When a postback is executed, I use the RaisePostBackEvent method to determine which method should be called. That way, it’s possible to trigger a postback via javascript. For example, I load a User Control via a postback that was triggered via javascript. However, the events of such a user control can’t be raised via postback anymore, because the RaisePostBackEvent method is called, rather than de default postback behaviour. So how can I call the default postback behaviour on a user control, from within the RaisePostBackEvent method?

public void RaisePostBackEvent (string eventArgument) {
    string eventTarget = Request ["__EVENTTARGET"];
    if (eventTarget == UniqueID) {
        eventArgument = Request ["__EVENTARGUMENT"];
        Action action = JsonConvert.DeserializeObject<Action>(eventArgument);
        if (action.name == "display") Display(action.argument);
        else if (action.name == "edit") Edit(action.edit);
    }
    else {
        // Control control = GetPostBackControl(this.Page);
        // !!! Raise the postback event on the control.
    }
}

I had this statement in the OnInit event method of the user control containing the javascript:

protected override void OnInit (EventArgs e) {
    Page.RegisterRequiresRaiseEvent(this);
}

When this statement is removed, it works.
