Getting started with the .NET MAUI Masked Entry control

We have seen the key features of the .NET MAUI Masked Entry control. Let’s see how to integrate it into your .NET MAUI app and utilize its basic features.

Step 1: First, create a .NET MAUI application.

Step 2: The Syncfusion .NET MAUI controls are available on the NuGet Gallery. To add the .NET MAUI Masked Entry control to your project, open the NuGet package manager in Visual Studio. Search for Syncfusion.Maui.Inputs and then install it.

Step 3: Register the handler for the Syncfusion core in the MauiProgram.cs file. Refer to the following code.

using Microsoft.Maui;
using Microsoft.Maui.Hosting;
using Microsoft.Maui.Controls.Compatibility;
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Syncfusion.Maui.Core.Hosting;
namespace MaskedEntrySample
{
  public static class MauiProgram
  {
        public static MauiApp CreateMauiApp()
        {
               var builder = MauiApp.CreateBuilder();
               builder
               .UseMauiApp<App>()
               .ConfigureSyncfusionCore()
               .ConfigureFonts(fonts =>
               {
                   fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
               });
               return builder.Build();
         }
  }
}

Step 4: Add the Syncfusion.Maui.Core and Syncfusion.Maui.Inputs namespaces to your XAML page.

xmlns:inputs="clr-namespace:Syncfusion.Maui.Inputs;assembly=Syncfusion.Maui.Inputs"

Step 5: Then, initialize the Syncfusion .NET MAUI Masked Entry control. For this demo, we are going to use the regex mask type for an email ID field.

<inputs:SfMaskedEntry x:Name="maskedEntry"
                      WidthRequest="300"
                      MaskType="RegEx"
                      Mask="[A-Za-z0-9._%-]+@[A-Za-z0-9]+\.[A-Za-z]{2,3}"/>

After executing the previous code examples, we will get a Masked Entry control like the following image.
