How to add 0 hour to SfTimePicker?

[Bryson Scales]

I'm using the SfTimePicker in a Xamarin Forms project and I would like to allow users to input 0 hours, 0 minutes and/or 0 seconds but if I use the hour, minute, or second interval properties this isn't possible. It would be great if the Syncfusion team could add bindable boolean properties called "AllowZeroHours," "AllowZeroMinutes," and "AllowZeroSeconds" to the SfTimePicker. If the boolean is set to true, it will add 0 to the column in the columns current format; if the boolean is set to false it will remove 0 from the column. This will let programmers who are using the interval properties allow users to input 0's on whichever columns they specify without breaking any code. I'm sure that I could create a custom SfPicker with my specifications but I use Syncfusion to avoid re-inventing the wheel.

Thanks,

Bryson

Hi Bryson,

As per the implementation, in the SfTimePicker control the significance of 0 value for hours, minutes and seconds, is to ensure the proper functioning of the time cycle and maintain the standard time cycle behavior.

For example, in a 12-hour time format, the hours are represented from 1-12 with an additional 0 which indicates the midnight or the midnoon. This 12 hour time format is divided into 12 intervals such as 0 to 1 as 1^st interval, 1-2 as 2^nd interval until 11 to 12 which is again 0 as the 12^th interval.

Removing the 0 from hour representation will disrupt the time cycle and the 12^th hour will no longer be distinguishable. Similarly for minutes and seconds.

To better understand your needs, could you please provide more information or use cases? This will assist us in evaluating your request and considering it for future implementation.

After reading your explanation on why there is no 0 hour in the SfTimePicker, I understand that it is designed to calculate a 24 hour offset that can be used when creating a DateTime object; it's basically a "TimeOffsetPicker." What I'm trying to do is use the SfTimePicker as a "TimePeriodPicker" for prompting a timed countdown with X # of days/hrs/mins/secs. The picker would start a 0d/0hr/0min/0sec then the user would be creating a TimeSpan from the entered values regardless of the meridiem. My intended functionality will require creating an entirely new control. Some name ideas are: SfIntervalPicker; SfPeriodPicker; or either of the names with "Time" added after the "Sf." Here are some examples of the intended inputs/outputs: 

- 30d/0hrs/0min/0sec => TimeSpan.FromDays(30);

- 0d/30hr/0min/0sec => TimeSpan.FromHours(30);

- 0d/0hr/30min/0sec => TimeSpan.FromMinutes(30);

- 0d/0hr/0min/30sec => TimeSpan.FromSeconds(30);

The output calculation would simply be adding days, hrs, mins, and seconds together and returning a TimeSpan value. Some practical customizations I can think of are the following:

- Day/Hr/Min/Sec Intervals (Although only min/sec seem useful in my opinion)

- Day/Hr/Min/Sec MaxValues (Maybe default to 60d/60hr/60min/60sec if this will maximize default performance)

- Day/Hr/Min/Sec Display Formatting (like the other SfPickers)

It would be amazing if this was added in a new update but if not, I would appreciate code for a SfPicker that can achieve my described functionality.

Thanks,

Bryson

Hi Bryson,

The SfTimePicker control in Xamarin.Forms is used to pick a time, but it does not have support to achieve your requirement 

However you can achieve your requirement "To hide input 0 hours, 0 minutes and 0 seconds" by creating custom time picker using the SfPicker control.

Please refer to the following UG link to know more about how to create a custom TimePicker using the SfPicker control.

We hope that this helped you. Please let know if you need further assistance.
