There's this odd bug/inconsitency I've been noticing with the latest DateTimePicker control. When you load the form initially, the very first time you click on a DateTimePicker to drop down the calendar and select a date, you must click on the date *twice* before the control will commit the selection.

Every selection after this will be immediately made (only two clicks required - drop down arrow & calendar number).

This feature has already tripped up some of my beta users - is there a way I can eliminate that first extra click?

Hi Pawz,

Indeed, this is something we have to fix. There is a workaround for this, which you can use until we fix the problem:

1. Subscribe to the SelectionChanged event of RadDateTimePicker's built in RadCalendar

      (this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).Calendar.SelectionChanged += new EventHandler(Form1_SelectionChanged);
     
2. Hide the PopUp when a selection has been made.

 void Form1_SelectionChanged(object sender, EventArgs e)
        {
            (this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).PopupControl.HideControl();
            this.radDateTimePicker1.Value = (this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).Calendar.SelectedDate;
        }

Please contact me again if there is something I can help with.

Kind regards,

Any update as to when this will be fixed.

I have a form that has 10+ RadDateTimePickers on it and I don't want to create an eventhandler for everyone. I tried to generalize the function like I have for setting the FocusDate of the RadDateTimePickerCalendar.Calendar.FocusedDate, but I haven't had much luck.  What I was trying to do was use the Enter event to create a selectionchanged event handler based on the sender argument. The problem I have is that when I handle the selectionchanged event the sender is RadCalendar which doesn't have the ability as far as I can tell to close the popup. See code below for what I was trying to accomplish before I discovered that the sender was RadCalendar.

private void radDateTimePicker_Enter(object sender, EventArgs e)
{
(((Telerik.WinControls.UI.
RadDateTimePicker)sender).DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).Calendar.SelectionChanged += new EventHandler(radDateTimePickerCalendar_SelectionChanged);
}

void

radDateTimePickerCalendar_SelectionChanged(object sender, EventArgs e)
{
(((Telerik.WinControls.UI.
RadDateTimePicker)sender).DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).PopupControl.HideControl();
}

The issue is in our TO DO list, Mark, and we will do our best to fix it for the Q3 release of RadControls for WinForms - hopefully the resources will permit us to do so. However you can subscribe to only one event handler in a loop and then in the handler you can call in a loop through all datetimepickers in your form to close their popups.


All the best,

Hi Dipak,

In a few days we will release Q3 SP1 and you won't need to write any additional code to hide the calendar popup. However, let me explain the code:

1. The following code hides the popup
(((Telerik.WinControls.UI.RadDateTimePicker)sender).DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar).PopupControl.HideControl();

2. We want the popup to be hidden on calendar's selection change. That is why I subscribe to the SelectionChanged event and call the HideControl method event's handler.
