Calling default event handler for my base class

[NWx]

Hi,

I defined a base class, Panel, based on System.Web.UI.UserControl, as below:


Public MustInherit Class Panel Inherits System.Web.UI.UserControl
.....


In another module, I want to define another custom control, Login, based on
Panel

Public MustInherit Class Login Inherits Panel

How can I call the event procedure for mz base class from the event
procedure of my child class?

For instance, I want to call Page_Load event of Panel from Page_Load of
Login class.

Thank you

Actually, you don't want to do that. If Panel is listening for the Load
event of the Page, then it will receive the event, otherwise not.

In other words, you don't have to do anything special beside declaring the
event handlers correctly with "Handles". Both the Page_Load of Login and the
Page_Load of Panel will be called.

Thank you, I noticed this later, by putting some breakpoints along calling
chain.

However, I noticed Page_Load is first called for Page itself, then for
custom controls. Is there any way to force calling Page_load first for the
parent control, and only after for the inherited control (and finally for
the page)?

Regards!

No, the order is unspecified. You cannot and should not depend on it.
