See how to use LinearGradientBrush and RadialGradientBrush, structure grid layouts and create a dynamic form using the Telerik DataForm in .NET MAUI.<\/span><\/p>\n

Have you ever seen apps with super fresh screens with gradients that make you think: \u201cOMG, where do I get that image to use as a background in my apps?\u201d \ud83d\udc40<\/p>\n

Well, today you won\u2019t just see a UI like that \u2026 you\u2019ll learn how to create it from scratch. This UI is inspired by a design from Dribbble<\/a>, and we\u2019ll recreate it step by step.<\/p>\n

Here\u2019s where it gets interesting: we\u2019ll build that super modern gradient using LinearGradientBrush<\/code> in .NET MAUI, without relying on external images, achieving that clean look directly from code.<\/p>\n

From there, we\u2019ll put together the entire experience: an onboarding screen with a clean and modern design, along with a registration form using the Progress Telerik UI for .NET MAUI DataForm<\/a>.<\/p>\n

The best part is that you\u2019ll understand every step of the process, from the background gradient to the structure of the form and how to use the components, so you can easily adapt it to your own projects.<\/p>\n

So let\u2019s get started, and you\u2019ll see how simple and fast it\u2019s to build a UI like this. \ud83d\ude80<\/p>\n

How Will the Explanation Work?<\/h2>\n

So you can understand everything 100%, I\u2019ll explain how the process will work:<\/p>\n

\u2796 Visual diagram:<\/strong> Before we start, you\u2019ll see a diagram with a screenshot of the design we want to achieve. This design will be divided into screens, each identified with a name and a color. Each one will be explained individually.<\/p>\n

\u2796 Code explanation per block:<\/strong> In addition to the written explanation, each screen includes a set of blocks with the exact code snippets you need to implement and achieve the final result.<\/p>\n

\u2796 Step-by-step visual progress:<\/strong> Each explanation will have its corresponding screenshot, so you can see the progress as we build the UI.<\/p>\n

\u26a0\ufe0f For this design, we took inspiration from an original Dribbble UI, but made some adaptations and adjustments to align it with the goals of this article.<\/p>\n

\ud83d\udd27 Environment Setup<\/h2>\n

You\u2019ll learn how to take advantage of some of the powerful Telerik UI for .NET MAUI components in this post. If you don\u2019t have the .NET MAUI library installed yet, visit the quick start page<\/a>, which explains step-by-step how to install Telerik UI for .NET MAUI, download the license key, configure the Telerik package source and install the Telerik MCP server (if needed).<\/p>\n

Breaking Down the Design<\/h2>\n

To make this easier to follow, I\u2019ve divided the design into clear blocks. We\u2019ll build each part one at a time, in the order you see below.<\/p>\n

\"Visual<\/p>\n

1. Onboarding<\/h2>\n

Oh yeahh! We\u2019ve reached the first screen! \ud83d\ude0e This is an onboarding screen, and I really like it because it\u2019s perfect for practicing XAML while building a modern UI.<\/p>\n

One of the highlights here is the gradient background. When we see something like this, it\u2019s easy to think we need an image to achieve it, but that\u2019s not the case. We\u2019ll build it from scratch using LinearGradientBrush<\/code> from .NET MAUI, giving you full control to customize and experiment with gradients directly from code, without relying on external assets.<\/p>\n

On top of that, this screen helps us structure a real layout by combining key UI elements: a centered image, a title with a description, and simple actions like a button and a \u201cSkip\u201d option.<\/p>\n

Adding the Gradient<\/h3>\n

To get started with the code, the first thing we\u2019ll create is the gradient that will be used as the background for the entire page. We\u2019ll assign it directly as the background of the ContentPage<\/code>.<\/p>\n

Using LinearGradientBrush<\/code>, add the following code block right before defining the main layout. Keep in mind that you can tweak each variation of the gradient using GradientStop<\/code>.<\/p>\n

 \r\n \r\n \r\n\t     \r\n\t     \r\n\t     \r\n\t     \r\n\t     \r\n\t     \r\n\t    <\/lineargradientbrush> \r\n    <\/contentpage.background>\r\n \r\n\r\n \r\n<\/contentpage>\r\n<\/code><\/pre>\n
Main Layout<\/h3>\n
Now let\u2019s continue with one of the most important components in a .xaml file: the main layout. For this screen, we\u2019ll add a Grid<\/strong> with two columns and five rows:<\/p>\n
 \r\n\t      \r\n<\/grid>\r\n<\/code><\/pre>\n
Keep in mind that this Grid<\/strong> will contain all the elements of your page, so it should be placed inside the ContentPage<\/strong>, exactly where the previous code block says: \u201cAdd your Grid here.\u201d<\/p>\n
The Halo<\/h3>\n
As you may notice, the main image has a kind of \u201chalo\u201d behind it, almost like a soft circle. In this case, we enhanced that effect using a RadialGradientBrush<\/strong>. \ud83d\ude0e<\/p>\n
This code block should be placed right at the beginning of the Grid<\/strong>, before adding the image and the rest of the elements.<\/p>\n
 \r\n \r\n\t     \r\n\t     \r\n\t\t     \r\n\t\t     \r\n\t\t     \r\n\t\t     \r\n\t\t     \r\n    <\/radialgradientbrush> \r\n    <\/ellipse.fill> \r\n<\/ellipse>\r\n<\/code><\/pre>\n
Main Images, Labels and Button<\/h3>\n
Now we\u2019ll continue by adding the remaining elements of the screen: the main image, labels and the button.<\/p>\n
