Adding Holidays on for ASP.NET tutorial

In ASP.NET WebForms, you can indeed use the BeforeCellRender event.

You just need to check whether the current cell falls on one of the defined holidays.

Example:

// Define an array of holidays
private static readonly DateTime[] Holidays = new DateTime[]
{
    new DateTime(2024, 12, 25), // Christmas
    new DateTime(2024, 1, 1),   // New Year's Day
    new DateTime(2024, 7, 4),   // Independence Day
    // Add more holidays as needed
};

protected void DayPilotScheduler1_BeforeCellRender(object sender, DayPilot.Web.Ui.Events.BeforeCellRenderEventArgs e)
{
    if (Holidays.Contains(e.Start.Date))
    {
        e.BackgroundColor = "#f8f8f8"; // Example color for holidays
    }
}
