DateTimePicker MinDate = MaxDate

[LIMA Factory]

Hello,

i use a DateTimePicker for my application to select a day. The selection is inside a very narrow time Intervall (1 - 3 Days). So i set the MinDate and MaxDate of the DateTimePicker accourdingly. When the Intervall is lager than 1 day the DateTimePicker works correctly. When the MinDate and the MaxDate is equal (only one day available, date cannot be changed) the display of the DateTimePicker is not correct:

Only the days before the actual date are grayed out.

It is possible to switch to different month / years (after teh actual date) with the build in functions.

Nevertheless is it not possible to select another day (which is good), but the user might get confused that his selection does not change the date.

Please confirm this behaviour and please provide a workaround for this behaviour.

Thank You.

Hello Ingo,

Thank you for writing.  

I have logged it in our feedback portal and I have added a vote for it on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the RadDateTimePickerCalendar.Calendar.ElementRender event and disable the cells that are not in the applied interval: 

public RadForm1()
{
    InitializeComponent();

    this.radDateTimePicker1.MinDate = DateTime.Now;
    this.radDateTimePicker1.MaxDate = DateTime.Now;

    RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
    calendarBehavior.Calendar.ElementRender += Calendar_ElementRender;
}

private void Calendar_ElementRender(object sender, RenderElementEventArgs e)
{
    if (e.Day.Date > this.radDateTimePicker1.MaxDate.Date || e.Day.Date < this.radDateTimePicker1.MinDate.Date)
    {
        e.Element.Enabled = false;
    }
    else
    {
        e.Element.Enabled = true;
    }
}

I hope this information helps. Should you have further questions I would be glad to help.
