What’s New in .NET MAUI: 2022 Volume 2

What’s New in .NET MAUI: 2022 Volume 2

As you know, Syncfusion rolled out its first three sets of .NET MAUI controls in the most recent Essential Studio releases. With the same spirit, we are happy to deliver our fourth set of .NET MAUI controls and cool features in the Essential Studio 2022 Volume 2 release. We’ll take a look at them in this blog.

Introducing the fourth set of .NET MAUI controls

In the 2022 Volume 2 release, we introduce the following .NET MAUI controls in preview mode:

  • DataGrid
  • Maps
  • Avatar View
  • Busy Indicator
  • Signature Pad

.NET MAUI DataGrid

The new .NET MAUI DataGrid control can display and manipulate data in a tabular view. It was built from the ground up to achieve the best possible performance, even when loading a huge volume of data.

Key features

  • Data binding: Bind different types of data sources, including data tables.
  • Column types: Show different data types in different types of columns. The following column types are supported: numeric, text, date, checkbox, image, and template. The template column is used to load any kind of control in a column.
  • Sorting: Interactively sort one or more columns.
  • Filtering: Programmatically filter data based on the criteria.
  • Column sizing: Set the width of columns with various sizing options. Columns can also be sized based on their content.
  • Auto-row height: Set the height for rows based on the content of their cells.
  • Selection: Select one or more rows. Keyboard navigation is supported for Windows and Mac Catalyst platforms.
  • Styling: Customize the appearance of cells and headers. Conditional styling is also supported.

.NET MAUI Maps

The .NET MAUI Maps control is a powerful data visualization component that displays the statistical information of a geographical area. It has highly interactive and customizable features such as selection, tooltip, legends, markers, bubbles, and color mapping. You can generate maps to show population density, sales, political boundaries, weather, elections, and route data.

Key features

  • Shape layers: Visualize the map area from GeoJSON or shapefile input data.
  • Data labels: Identify shapes by displaying their names. If the labels exceed the shape bounds, they are trimmed or hidden.
  • Markers: Denote a location with built-in symbols or display custom content at a specific latitude and longitude on a map.
  • Bubbles: Add information to shapes such as population density or number of users. Bubbles can be rendered in different colors and sizes based on the data values of their assigned shapes.
  • Shape selection: Select a shape to highlight a region on a map. You can use the callback for performing actions while selecting the shapes.
  • Legends: Use legends to show clear information about the data plotted on a map.
  • Colors: Categorize the shapes on a map by assigning their colors based on their underlying values. Also, it is possible to set a shape color for a specific value or for a range of values.
  • Tooltip: Display additional information about shapes, markers, and bubbles using a customizable tooltip.

.NET MAUI Avatar View

The .NET MAUI Avatar View control provides a graphical representation of a user’s image. You can customize the view by adding an image, gradient background, group view, and more.

  • Realistic, handwritten look and feel: The unique stroke-rendering algorithm draws the signature based on the speed of the drawn gestures along with minimum and maximum stroke thicknesses. This gives a realistic, handwritten look and feel to the signature.
