SaaS applications, also known as multi-tenant applications, are very popular these days. A single instance of the software is available to multiple customers/tenants. Each tenant’s data is isolated and remains invisible to other tenants. All tenant databases have the same structure. The data is different, of course.

Tri-part events are a special code snippets that provide a convenient way of programming interactions between the browser and the webserver.

Why three parts?

Any web application consists of two parts – server and client. The client part runs in the browser on the computer of the web site visitor. This part takes care of all user interface interactions, such as buttons, input controls, blocks of text and images. Client-side code is written in Javascript in most cases.

Server part – this code runs on the webserver itself and has direct access to the database, can send emails, read and write files to the disk. In PHPRunner-created applications server code language is PHP, ASPRunner.NET uses C# or VB.NET, ASPRunnerPro uses Classic ASP.

Most real-life tasks though require a joint action of both client and server parts. For example, the user presses a button and wants something changed in the database, or an email being sent.
Tri-part events provide a relatively easy way to create such integrated code snippets.

They consist of three parts running one after another:

• Client Before – this Javascript code is run immediately after user’s action such as pressing the button.
• Server – this part runs on the server after the Client Before part has finished. You can only user server-side code here (PHP, C# or ASP).
• Client After – back to the web browser, another Javascript code part.

If you purchased or upgraded PHPRunner, or ASPRunner.NET less than one year ago logon to control panel and find download links and registration keys under ‘My purchases’. There should be ‘Reg info’ link next to your latest upgrade purchase.

Note: Software maintenance coverage needs to be continuous. If your last purchase or upgrade were more than one year ago you have till June 20, 2019 to renew your maintenance. After that date you will have to purchase PHPRunner, ASPRunner.NET or ASPRunnerPro at the full price.

What’s new in version 10.2

Collapsible menu bar

Hide/collapse menu bar on the left. This feature is inspired by AdminLTE template.

Page Designer is one of the most amazing new features in version 10 but as any new functionality it also introduces a learning curve. In this article we are answering the most common questions people ask us about Page Designer usage.

If you have Page Designer questions that are not answered in this article feel free to ask here in comments or via helpdesk.

How to work with additional pages?

In version 10 you can add extra pages of the same type. For instance, besides the main edit page you can have extra edit pages named edit1, edit2 etc. The big question is how to use these additional pages in your application.

Changing button properties

Since we created multiple edit pages lets see how we can use those. On the List page select Edit button. On the right side using ‘Page’ dropdown select the page this button will open.
