How to set a text column of an .NET MAUI DataGrid (SfDataGrid) to initially display with password characters ?

In this article, we will demonstrate how to set a text column to initially display as password characters in .NET MAUI DataGrid.

C#
The following code illustrates how to set a text column to initially display with password characters in a DataGrid.

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        sfGrid.CellRenderers.Remove("Text");
        sfGrid.CellRenderers.Add("Text", new PasswordCellRenderer());
    }

}

public class PasswordCellRenderer : DataGridTextBoxCellRenderer
{
    private string originalPassword;
    protected override void OnInitializeDisplayView(DataColumnBase dataColumn, SfDataGridLabel? view)
    {
        base.OnInitializeDisplayView(dataColumn, view);
        var mappingName = dataColumn.DataGridColumn.MappingName;
        if (view != null && mappingName == "Name")
        {
            originalPassword = dataColumn.CellValue?.ToString();
            view.Text = new string('●', originalPassword?.Length ?? 0);
            view.GestureRecognizers.Add(new TapGestureRecognizer
            {
                Command = new Command(() => OnCellTapped(view, dataColumn))
            });
        }
    }
    private void OnCellTapped(SfDataGridLabel? passwordCell, DataColumnBase dataColumn)
    {
        passwordCell.Text = dataColumn.CellValue.ToString();
        Device.StartTimer(TimeSpan.FromSeconds(1), () =>
        {
            passwordCell.Text = new string('●', originalPassword.Length);
            return false;
        });
    }
    public override void OnInitializeEditView(DataColumnBase dataColumn, SfDataGridEntry view)
    {
        base.OnInitializeEditView(dataColumn, view);
        var mappingName = dataColumn.DataGridColumn.MappingName;
        if (view != null && mappingName == "Passwrd")
        {
            view.IsPassword = true;
        }
    }
}
