    Catching Exceptions on a Master Page

    I'm trying to catch, and handle, some database exceptions on a masterpage I've created. I've tried adding the following to the masterpage codebehind:

            public void PageError( object sender, EventArgs e )
            {
                int i = 9;
                i++;
            }

            protected override void HandleException( PageExceptionArgs args )
            {
                base.HandleException(args);
            }

    Neither of these methods ever get called.

    Is Umbraco intercepting exceptions at a deeper level, before the page "sees" them? Or is this lack of firing due to the fact that the code is on a masterpage, not a page?

    It seems the issue is not with Umbraco, but rather with how masterpages work. The OnError() handler for a masterpage doesn't get called when there's an error on the page it defines.

    However, you can add an event handler (on every page load) to call a Page_Error routine which in turn calls OnError():

            protected override void OnLoad( EventArgs e )
            {
                base.OnLoad(e);

                this.Page.Error += new EventHandler(Page_Error);
            }

            protected void Page_Error( object sender, EventArgs e )
            {
            }

    Which works well enough.
