How to get the state of a checkbox while editing in .NET MAUI DataGrid (SfDataGrid) ?

In this article, we will demonstrate how to get the state of a checkbox while editing in the .NET MAUI DataGrid.

xaml

<syncfusion:SfDataGrid x:Name="dataGrid" 
                       AutoGenerateColumnsMode="None"
                       ColumnWidthMode="Auto"
                       GridLinesVisibility="Both"
                       HeaderGridLinesVisibility="Both"
                       ItemsSource="{Binding Employees}">
    <syncfusion:SfDataGrid.Columns>
        <syncfusion:DataGridCheckBoxColumn MappingName="EmployeeStatus"
                                           HeaderText="Employee Status" />
        <syncfusion:DataGridTextColumn MappingName="EmployeeID"
                                       HeaderText="Employee ID" />
        <syncfusion:DataGridTextColumn MappingName="Name"
                                       HeaderText="Employee Name" />
        <syncfusion:DataGridTextColumn MappingName="Title"
                                       HeaderText="Designation" />
    </syncfusion:SfDataGrid.Columns>

</syncfusion:SfDataGrid>

C#
The code below illustrates how to get the state of a checkbox while editing in the DataGrid.

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        this.dataGrid.CellRenderers.Remove("CheckBox");
        dataGrid.CellRenderers.Add("CheckBox", new DataGridCheckBoxCellRendererExt());
    }
}

public class DataGridCheckBoxCellRendererExt : DataGridCheckBoxCellRenderer
{
    protected override void OnInitializeDisplayView(DataColumnBase dataColumn, StackLayout? view)
    {
        base.OnInitializeDisplayView(dataColumn, view);

        if (view != null && view.Children[0] is CheckBox checkBox)
        {
            checkBox.PropertyChanging += DataGridCheckBoxCellRendererExt_PropertyChanging;

            checkBox.PropertyChanged += DataGridCheckBoxCellRendererExt_PropertyChanged;
        }
    }

    private async void DataGridCheckBoxCellRendererExt_PropertyChanged(object? sender, System.ComponentModel.PropertyChangedEventArgs e)
    {
        var checkBox = sender as CheckBox;

        if (e.PropertyName == "IsChecked" && checkBox != null && checkBox.IsFocused && !DataGrid!.View!.IsEditingItem)
        {
            var isChecked = (sender as CheckBox)?.IsChecked ?? false;

            // Display an alert dialog
            await Application.Current.MainPage.DisplayAlert(
                "Checkbox State Changed",
                $"IsChecked: {isChecked}",
                "OK"
            );
        }
    }

    private async void DataGridCheckBoxCellRendererExt_PropertyChanging(object sender, PropertyChangingEventArgs e)
    {
        var checkBox = sender as CheckBox;

        if (e.PropertyName == "IsChecked" && checkBox != null && checkBox.IsFocused && !DataGrid!.View!.IsEditingItem)
        {
            var isChecked = (sender as CheckBox)?.IsChecked ?? false;

            // Display an alert dialog
            await Application.Current.MainPage.DisplayAlert(
                "Checkbox State Changed",
                $"IsChecked: {isChecked}",
                "OK"
            );
        }
    }
}
