How to Receive the Text Changed Event in the .NET MAUI Autocomplete?

This article demonstrates how to receive the Text Changed event in the .NET MAUI Autocomplete. While there is currently no direct event support for TextChanged, you can utilize the TextChanged event from the Entry element, which is a child of the .NET MAUI Autocomplete, to set up an event handler that responds to text changes. Here’s how you can achieve this:

C#

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        
        // Get the Entry control from SfAutocomplete
        var entry = GetEntryFromAutoComplete(autoComplete);
        if (entry != null)
        {
            // Attach the TextChanged event handler
            entry.TextChanged += MainPage_TextChanged;
        }
    }

    private void MainPage_TextChanged(object? sender, TextChangedEventArgs e)
    {
        // Handle the text change event here
    }
    
    private Entry? GetEntryFromAutocomplete(SfAutocomplete sfAutocomplete)
    {
        foreach (var child in sfAutocomplete.Children)
        {
            if (child is Entry entry)
            {
                return entry;
            }
        }
        return null;
    }
}
