Hello and welcome to the 2025 journey of .NET MAUI!
In this article, we will explore how to build dynamic user interfaces with decision logic in .NET MAUI using XAML.
Dynamic UIs are essential for creating responsive and engaging applications that adapt to user input, application state, or external conditions. By leveraging data bindings, triggers, converters, and behaviors, you can implement dynamic UI elements that enhance the user experience and improve the efficiency of your .NET MAUI applications.
Out of the box concepts for Dynamic UI in .NET MAUI
1. Data Binding
Data binding connects UI elements to data sources, enabling automatic updates when data changes. Use the {Binding} syntax to bind properties in XAML.
Example:
2. Triggers
Triggers let you change UI properties based on conditions.
Example:
3. Value Converters
Converters allow you to transform data from one format to another before displaying it.
Example:
XAML Usage:
4. Behaviors
Behaviors add reusable, event-driven functionality to controls.
Example:
XAML Usage:
But sometimes you want to add If and Switch conditions directly in your XAML for more dynamic UI capabilities. This makes it easier to handle conditional rendering without relying heavily on code-behind logic.
Let's create a ConditionView and SwitchCaseView that allow you to define If and Switch conditions in XAML.
ConditionView
The ConditionView control renders its content based on a condition.
XAML Usage:
In this example, the rendered content will depend on Condition flag.
Switch Case View
The SwitchCaseView control renders content based on multiple cases.
XAML Usage:
This SwitchCaseView will display a different Label depending on the Case value.
Conclusion
Dynamic UI in .NET MAUI XAML empowers developers to create responsive, user-centric applications with minimal code. By combining data bindings, triggers, converters, behaviors, and controls like ConditionView and SwitchCaseView, you can handle complex UI requirements efficiently.
