How do I reuse code in the Code-Behind section of an ASPX page

Author	Message
Jim Ada #1 / 6	How do I reuse code in the Code-Behind section of an ASPX page Does anyone know how to "include" a block of code in the code-behind (.vb) file of an ASPX page that retains the ability to call a Response.Redirect? I DO NOT want to use an include file on the Design/HTML side. What I want, is to have a block of code that I can reuse in the Code-Behind section of my ASPX pages. In this block of code I am doing a Response.Redirect (this response.redirect cannot be stripped out of the code block). I have been unsuccessful in implementing a Response.Redirect from a Class file directly. Does anyone know how to include a file in the Code-Behind section of an ASPX Page or Perform a Response.Redirect from a Class File? Any help on this matter is greatly appreciated.

Jay B. Harlow [MVP - Outlook #2 / 6	How do I reuse code in the Code-Behind section of an ASPX page Jim, Use inheritance. This assumes you are using VS.NET CodeBehind model, not the src= code behind model. Your page1.aspx would inherit from Class Page1 in page1.aspx.vb Class Page1 would inherit from class PageBase. (manual change source) Class PageBase would be a 'standalone' class that is added to the project. Which inherits from System.Web.UI.Page Your 'block of code' would be implemented as a method of PageBase. Page1 would invoke the method where the block is needed... Depending on where the block is really needed, PageBase could override one of Page's methods, or handle one of the Events of Page. Leaving Page1 unaware...

Jim Ada #3 / 6	How do I reuse code in the Code-Behind section of an ASPX page Jay, Thank you very much. Using inheritance works perfectly. I knew there had to be an easy way to accomplish this one.

Jeff Rhode #4 / 6	How do I reuse code in the Code-Behind section of an ASPX page Jay, This was a very useful response as I was unaware that you could inherit from another page in Web Forms, I guess because there is not a menu item like there is in Windows Forms. I just tried it and the code is available (and the parent page's page_load code is called), but there is no visual inheritance. Is there any way to share visual elements? Also, any problems in using modules to share code in this scenario instead (besides not being OOP)? Thanks! Jeff Rhodes Quote: > Jim, > Use inheritance.

Jay B. Harlow [MVP - Outlook #5 / 6	How do I reuse code in the Code-Behind section of an ASPX page Jeff, Web Form Visual Inheritance is not really there... I would expect to be able to handle some events or override methods would allow to me to inject code into the page, Control.Render for example. There was an article on DevX on one method of doing, but I cannot find it right now... Possible its http://www.devx.com/upload/free/features/vbpj/2001/12dec01/an0112/an0... sp, which is for members only now... Using modules, you would not have access the properties of the Page, you would need to pass them as parameters (Response, Request, Session, Application, Server, Cache...). And of course it would not be OOP ;-). Not to say it would not be useful in some applications... Hope this helps Jay Quote: > Jay, > This was a very useful response as I was unaware that you could inherit from > another page in Web Forms, I guess because there is not a menu item like > there is in Windows Forms.
