I'm fairly new to .NET programming.

The DateTimePicker control seems to be a great solution for entering valid dates without alot of backend checking and preventing the user from entering a bad date. However it seems like I always have to explain to my testers that they don't have to use the drop down box to scroll back 15 years. After I show them they can type they love it. Especially seeing what "day of the week" events take place.

Is this control the best way to handle birthdates, anniversaries, etc?

Building on ’s question and ’s experience, the right choice depends on the task: identity dates (birth, anniversary) should be treated as date-only data with tight validation, while form-heavy or high-throughput scenarios favor a compact, keyboard-first entry. A robust pattern combines a simple typed input (clear localized format hint) with an optional calendar popover that supports a fast "jump-to-year" and a live helper that shows age or weekday — this keeps data entry fast for power users while still assisting discovery for others.

Practical rules: accept multiple common formats but parse with culture-aware logic, show an immediate, human-friendly validation message (future dates, implausible ages like >120, and leap-year edge cases), and allow partial dates when appropriate (separate nullable day/month/year fields or an explicit "day unknown" option). Make controls keyboard-accessible and expose ARIA labels so screen readers read the field meaningfully. For grids, use inline typed cells for speed and open a richer editor only on demand.

Example: a compact C# parse + sanity check (DateOnly can replace DateTime on .NET 6+):

using System;
using System.Globalization;

public static bool TryParseUserDate(string input, out DateTime date)
{
    date = default;
    if (string.IsNullOrWhiteSpace(input)) return false;
    var formats = new[] { "yyyy-MM-dd", "MM/dd/yyyy", "M/d/yyyy", "dd/MM/yyyy", "d/M/yyyy" };
    if (DateTime.TryParseExact(input, formats, CultureInfo.CurrentCulture, DateTimeStyles.None, out date))
        return IsReasonable(date);
    if (DateTime.TryParse(input, CultureInfo.CurrentCulture, DateTimeStyles.None, out date))
        return IsReasonable(date);
    return false;
}

static bool IsReasonable(DateTime d)
{
    var today = DateTime.Today;
    var min = today.AddYears(-150);
    var max = today.AddYears(1);
    return d >= min && d <= max;
}

Store birth/anniversary values as a date-only type (DB date or .NET DateOnly), never rely on time-zone conversions that can shift the day; keep server-side validation and unit tests for multiple cultures and leap-year/boundary ages. These choices balance speed, accuracy, and discoverability for both testers and end users.

I usually end up using a masked text box or text box for dates. The validation code can be packaged up into a nice reusable class, and my users don't have as much usability trouble. There's also consistency with my data grids. I wrote some date time picker column types and they really destroy the speed of workflow, so I use text box columns or masked text box columns there too. :)

But that's me. The DateTimePicker control is great when people know how to use it and it's placed carefully. Just like every other control. ;)
