[Solved] How to Create Class Library or Global procedure to eliminate Redundant/Duplicate Codes...

[gc_0620]

Hi,

Environment: ASP.NET AJAX Q2 2009 SP1 with VStudio SP1.

 

I am creating a site with Master->Detail Content pages (about 4). Currently in each Content Page code behind file  Page_Prerender Event, it calls another Procedure ShowHideMasterMenu. Both are in the same code behind file. I am repeating the same below codes for all content pages because all does the exactly same thing.

 

My question is there any way I can put the codes of public void ShowHideMasterMenu() into a class library or into a Public Procedure  and call it from all content pages Page_Prerender event? Below code (public void ShowHideMasterMenu() ) works but they are redundant and repeating codes for each content page.

 

Any help or pointing to right direction will be appreciated.

 

Sincerely

Try overriding the Render method in your master page.  It may be too late in the page life cycle, but give it a whirl.

Thanks Thomas but I have no clue how to use Render method in master page.

All I want to create a Class Library or Global Procedure for the Codes that I coded in ShowHideMasterMenu. My intention is that each content page in their Page_Render event call that Class Libray or Global Procedure and execute it because each of those content pages Pre_Render events are the same (i.e. not to repeat the same codes in each content page).

[Thomas Salt]

My mistake.  You can just create a class, put the code in that class, and then reference that class and call the appropriate function in each pages pre render event.

here is an article. http://www.aspfree.com/c/a/C-Sharp/C-Sharp-Classes-Explained/

as for a reference..here is an example of the signature for the override event to put in a master page...

protected override void Render(HtmlTextWriter writer) {

    MyBase.Render(writer); [NOTE: this is vb syntax]
    }

Thomas,
 
It did not work. I am getting below error message. Below is my code also.  I wounder if Telerik has some sample project or Tutorial for what I am trying to do.

Thanks

Try changing Sessions to HttpContext.Current.Session

I'm not sure why you have the system.web.ui.page extension..
public class PaClass : System.Web.UI.Page

{

 public static string PaSayHellow()   

    {

        return "Hello World Say Hellow!";  //this works

    }

 

Try changing it just to and then referencing your static procedure
public class PaClass

{
