"ASP. NET 2.0 secrets" Reading Notes (7)

* Path: for WebProgramPath tools and methods

* The user control cannot be in the same directory as the reference page, so it is best to separate a directory for the user control;

* Ajax: implements the icallbackeventhandler interface, which contains the callback method;

* Page. loadcontrol (): You can dynamically load user controls;

* <% @ Reference control = "%>: indicates a type reference. After the control is loaded, it can be converted to the property of the original control;

* Multi-page Wizard: This function seems to have been implemented by a control. Run the iwizardstep interface to put void loadstep () and bool nextstep () respectively ();
