Simple Mendix Counter Example - Mendix Typing CST Test
Simple Mendix Counter Example — Mendix Code
A basic Mendix example that increments a counter when a button is clicked and updates a text widget in real time.
# mendix/demo/CounterApp
1. Create an Entity 'Counter' with an attribute 'Value'.
2. Drag a Button widget onto the page.
3. Drag a Text widget to display 'Counter.Value'.
4. Configure Microflow: On Button Click -> Change 'Counter.Value' = 'Counter.Value + 1'.
5. Bind Text widget to show current 'Counter.Value'.
6. Preview the app to interact with the counter live.Mendix Language Guide
