DateTime to "Time" in a DataGridView - c#

Good morning!
I have a Form which has a DataGridView with a few time informations that I have to show it on a label.
But as I can see, my label (and DataGrid) have Date and Time included (and I only need the time on my DataGrid and label).
I know visual studio c# doesn't has a style that converts DateTime only to "Time", but I don't know how to format these datas only as Time to show it on my label.
What should I do to:
Format this DateTime only to show Time (on my DataGrid) and then appears only as Time on my label as well (this label retrieves the DataGrid information).

Set DefaultCellStyle
dataGridView1.Columns["Column with time"].DefaultCellStyle.Format = "HH:mm:ss";

How to set Format for DateTimePicker in WPF

In my application I'm using the DateTimePicker control from the Xceed Wpf toolkit.
I would like to set the format so that only the hours and minutes can be edited, I want to remove the calendar. since I'm using DateTimePicker to establish how long a process takes. Like this 3d print, it took 20h 40m and save it in my database.
enter image description here only this part
To set the format of the Xceed DateTimePicker control to only show hours and minutes, you can set the Format property to "HH:mm". This will display the time in hours and minutes, and only the time portion can be edited.
Example:
<xctk:DateTimePicker Format="HH:mm" />
This will format the control to only show and allow editing of the hour and minute values.

Change value of DateTimePicker

I'm having problem to change the displayed value of my DateTimePicker object in C# Winforms
I'm trying to change the date in the DateTimePicker according to the value, but the display won't change.
dtpDisplayTo.Value = DateTime.Today;
I know this is dated, but I just had the same problem and found a solution with a bit of research. You have to set the Checked property of the DateTimePicker to True before changing the date, otherwise the control will consider the change as null and not show the new date. Really strange stuff.
DateTimePicker displays today's date instead of displaying its actual Value

How to format a column in DataGridView with C#

I used BindingSource to connect my DataGridView with a Microsoft Access DB.
The field in the DB is a Time is a Long Time (Input Mask is 99:00 >LL;0;_)
The DataGridView shows
12/30/1899 9:56 AM
The time is correct but the DataGridView is showing the 12/30/1899
Please help!
you want to set the DefaultCellStyle.Format = "t"
you can display only the time via the properties window for your `datagridview', look for the Columns option. Then select your column that you want to change > DefaultCellStyle > Format > Date Time > time option.
or in code:
dataGridView1.Columns["yourColumnName"].DefaultCellStyle.Format = "t";
here is some info on formatting data in a datagridview

Datagridview DateTime Format not using System Region settings

I've got a datagridview that is hooked up to a bindingsource on my main form. One of the columns and datamembers in the bindingsource is a DateTime object. When the datagridview shows this item it doesn't use Window's default region settings for displaying datetime.
The weird thing is, I can access this same DateTime object and print it to a text box, or even pass it off to another form with another datagridview and binding source and it actually shows up properly in that table.
So then, why does the datagridview on my main form not use the regional date/time settings when converting the DateTime object to a string?
I've checked that there was no special formatting applied to the datagridview and so I'm running out of ideas to check.
Do you guys know if there is any super secret way to get a datagridview to follow system regional format rules or not?
Also, since I highly doubt that I did something different with this datagridview vs the others in my application, the next potential area for issue could be on application load: Perhaps since this comes up when the application loads, it's not getting the same cultureUI settings as the other datagridviews?
Update I've tried adding another column to the datagrid view and hooking it up to the same data property (datetime) and I get the same result. So something about how entire datagridview, or how it was created is stopping the "ToString" from using the default regional settings.
Any Help?
On design, in the Edit Columns dialog of the DataGridView:
Search for property DefaultCellStyle, and open this dialog;
Search for property Format and choose Date format;
Choose your favorite format.
