hi i have a datepicker in my winforms and i want to disable the date exists in my dataBase?
num_reglement = date_paiement.Text + "-" + txtMatricule.Text;
paiement save_paiement = new paiement(num_reglement, double.Parse(txtmontantht.Text),
cmb_paiement.Text, txtbanque.Text, txt_cheque.Text,
date_paiement.Value.Date.ToShortDateString(), txtMatricule.Text, txtlibelle.Text);
save_paiement.insert();
I don't think date time Picker has any such property. It has Max-Date, Min-Date property if you have valid date range, if you want to validate from database ,Only way is to check in Text changed event if value exits in database and show popup of rejection.Otherwise use some third party Control.

The question sounds illogical, but it is not:
I have 2 dates "Target" and "Actual". Usually the "Actual" date is very close to "Target", but not necessarily to the current date. To avoid the multiple clicks in the calendar that would navigate you to the month/year of interest, I set the selected date to my "Target" date when it is opened. This works great, BUT does not allow me to select that day, with the calendar closing automatically after selecting.
Any idea to solve this or any known alternative?
If you have a Calendar1 component, you can use a code like:
DateTime tomorrow = DateTime.Today.AddDays(1);
Calendar1.TodaysDate = tomorrow;
Calendar1.SelectedDate = Calendar1.TodaysDate;
When this calendar changed SelectionChanged the selected date, you can set the other calendar.
Tell me if you need more detail.
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
I have a date picker control that I use for a data collection application. It is using MvvM data binding. When going through a list of dates (see fig1) it will populate the date picker correctly. Whenever I hit new, the date pickers are nulled out. When I pull up the popup, it selects the month and year from the previous date that was set to. (fig 2) Is there anyway to default the pop up show the current month in the current year?
Note : I would like to keep the selected date to null on a new entry to force some validation.

The following image is to show what happens when I set the DisplayDateStart.
(original answer was horribly wrong, sorry about that)
Okay, lets try this again.
Have you tried setting the fallback to today's date?
SelectedDate="{Binding TehDate, FallbackValue={x:Static sys:DateTime.Now}}"
I am working with WPF and C#. I want to fire an event when the user modifies or selects a date on my raddatepicker control. What event handler should I be using for this? I want to be able to convert this captured date to a SQL server 'datetime' variable for use in the backend.
SelectionChanged is fired when a date is selected or typed + validated.
i have a gridview that dynamically generate datepicker , i have taken the value of datepicker using
GMDatePicker dtp = (GMDatePicker)Gridview1.Rows[rowIndex].Cells[3].FindControl("frmdate_starttime");
and i have inserted using dtp.Date,while storing in the database it only store the date and not the time. how to retrive the time to save in database along with date
You can change the Format property to Custom and the CustomFormat property to what you require, something like dd MMM yyyy hh:mm.
You should then be able to use
DateTime dt = dateTimePicker1.Value;
to get the date and time.
Split the problem into two parts: are you getting the right value out of the control but failing to save/restore it in the database correctly, or are you failing to get the right value out of the control in the first place? Once you've worked out whether it's a UI or database problem, you can ignore the other half of it.
Have you enabled the time picker in the control?
What column type are you using in the database?
If you run your application in the debugger, what value do you see before you store it in the database?
If you run a query against the database in the relevant admin tool, does that show a time?
