DateTimePicker: Highlight today's date only

[Ian]

Hi,

Is there a way to highlight today's date only and not the selected date on dateTimePicker's calendar?

Many Thanks,

Ian

Hello,

Thank you for contacting us.

You should set CallendarCell Focused property to False in the PopupControl_PopupOpened event.
Please refer to the code below:

public partial class Form1 : Form
    {
        RadDateTimePickerCalendar calendar;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            calendar = (RadDateTimePickerCalendar)this.radDateTimePicker1.DateTimePickerElement.CurrentBehavior;
            calendar.PopupControl.PopupOpened += new RadPopupOpenedEventHandler(PopupControl_PopupOpened);
        }

        void PopupControl_PopupOpened(object sender, EventArgs args)
        {
            RadElementCollection children = calendar.Calendar.CalendarElement.CalendarVisualElement.Children[0].Children[1].Children;
            for (int i = 0; i < children.Count;++i)
            {
                CalendarCellElement cell = (CalendarCellElement)children[i];
                if (cell.Focused)
                {
                    cell.Focused = false;
                }
            }
        }
    }

I hope this helps.

Kind regards,

Hi Peter,

Thank you for your reply. The code is not working but when I added "cell.Selected = false;" after "cell.Focused= false;", it's working now. Thank you for the answer.

Kind regards,

Ian

Hi,

I found a bug in this solution. While still on the calender, if you move forward a month and then return back to the current month, both the selected date and date today is highlighted. I tried adding the code in radDateTimePicker1.Calendar.MouseClick event but it's still not working. I hope you can help me with this.

Many Thanks,

Ian

Hi Ian,

Thank you for writing back.

To handle all similar cases you should handle Paint event - this is not the best practice and we do not recommend it, but is the only possible solution to achieve the desired behavior.

Please, refer to the code below:

public partial class Form1 : Form

{

    RadDateTimePickerCalendar calendar;

    public Form1()

    {

        InitializeComponent();

    }

 

    private void Form1_Load(object sender, EventArgs e)

    {

        calendar = (RadDateTimePickerCalendar)this.radDateTimePicker1.DateTimePickerElement.CurrentBehavior;
        calendar.Calendar.Paint += new PaintEventHandler(Calendar_Paint);

         

    }

 

    void Calendar_Paint(object sender, PaintEventArgs e)

    {

        RadElementCollection children = calendar.Calendar.CalendarElement.CalendarVisualElement.Children[0].Children[1].Children;

        for (int i = 0; i < children.Count; ++i)

        {

            CalendarCellElement cell = (CalendarCellElement)children[i];

            if (cell.Focused)

            {

                cell.Focused = false;

                cell.Selected = false;

            }

        }

    }

 

    

}

I hope this helps. All the best,
