Introduction to the Course.

History Management in DataFlex

In this first lesson we will take a quick, broader look at what DataFlex does to facilitate History Management.

Enabling History Management

Now that we've covered the basics we will start getting into some more technical stuff. In this lesson we will look look at how you can turn on History Management and what this does for your application.

In this lesson we're going to go through 1 of 2 important components of DataFlex History Management: the State Hash. The State Hash is used by DataFlex to uniquely identify the state of the WebApp. It tells you what view you're in, how you got there and which record you're looking at.

Navigation Paths

In this lesson we'll cover another important component, the Navigation Paths. Navigation paths are used within the Framework to determine how your app navigates from one view to the next. Each navigation path must be registered for the history management to function as intended.

Manipulating the statehash view name

In this lesson we're going to look at a simple way to change the content of the StateHash.

Custom statehash

In the last lesson we explored a quick and easy way to change the view name portion of the statehash. In this lesson we're going to look at how we can change and use the custom state hash.

In this lesson we'll quickly go through how you can manually change the title of your application.

Tips and Tricks

In this lesson we'll cover some tips and tricks you can use in certain situations.
