Hi.

When you select a time from the selection box is possible to auto-close? At the moment you have to select the icon again for the calendar to be removed.


Thanks P

Hi Paul,

 Currently the DateTimePicker control closes its popup when value is selected with the mouse only if it its InputMode is DatePicker or TimePicker. If you want to change this behavior you need to handle the DateTimeSelectedWithMouseEvent routed event of the RadDateTimePicker control (it is not exposed as a CLR event, but you can still handle it). Here is our current code that closes the DateTimePicker drop-down. What you will need to do is similar:

EventManager.RegisterClassHandler(typeof(RadDateTimePicker), RadDateTimePicker.DateTimeSelectedWithMouseEvent, new RoutedEventHandler(OnDateTimeSelectedWithMouse));
 
 
private static void OnDateTimeSelectedWithMouse(object sender, RoutedEventArgs args)
{
    var picker = sender as RadDateTimePicker;
 
    // If the picker is not a DateTimePicker and the drop-down is opened than close it.
    if (picker != null && picker.InputMode != InputMode.DateTimePicker && picker.IsDropDownOpen)
    {
        picker.IsDropDownOpen = false;
    }
}

Best wishes,

Hi Miroslav,

We have a DateTimePicker where the inputmode is DateTimePicker. However we only want to close the dropdown when the Time is selected. You solution does not cater for this.

Can you propose a way to do this using your DateTimeSelectedWithMouseEvent. We just need to test that the Time portion of the control has been selected.

Thanks
Simon

Hello,

What I would suggest you is to change the code in the event handler with the following:

var picker = sender as RadDateTimePicker;
 
// If the picker is not a DateTimePicker and the drop-down is opened than close it.
if (picker != null && picker.IsDropDownOpen && ((RadRoutedEventArgs)args).Source is RadClock)
{
    picker.IsDropDownOpen = false;
}

The idea is to identify which control was actually clicked - the calendar or the clock and if the clock is clicked, than close the drop down.

Hope this helps.

I succeeded with auto close in case of time input section selected. Using this

EventManager.RegisterClassHandler(
typeof(RadDateTimePicker), RadDateTimePicker.DateTimeSelectedWithMouseEvent, new RoutedEventHandler(OnDateTimeSelectedWithMouse));
private static void OnDateTimeSelectedWithMouse(object sender, RoutedEventArgs args)
{
var picker = sender as RadDateTimePicker;
// If the picker is a DateTimePicker and the drop-down is opened than close it if mouse down on time selection.
if (picker != null && picker.InputMode == InputMode.DateTimePicker && picker.IsDropDownOpen &&(args).OriginalSource is RadClock)
{
picker.IsDropDownOpen = false;
}
}

I implemented a custom 'Today' button using my own style, and I had the same problem: the DateTimePicker does not close automatically after pressing 'Today' (while this works perfect when clicking any Date in the DateTimePicker).
Now I'm using the fix described above, and it works like a charm:

        private void DatePicker_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            ViewModel.CurrentPeriodChangeInfo.CurrentDate = DateTimePicker.DisplayDate;
            DateTimePicker.IsDropDownOpen = false;
        }
