Hello
I have control, which inherits from RadDateTimePicker. I use it across my whole application to ensure consistency.

public class RadMaskedDatePicker : RadDateTimePicker
{
    public RadMaskedDatePicker()
    {
        InitializeComponent();
    }
 
    private void InitializeComponent()
    {
        this.Format = DateTimePickerFormat.Short;
        InitializeFooter();
    }
 
    private void InitializeFooter()
    {
        RadDateTimePickerCalendar datePickerCalendarBehavior = this.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
        if (datePickerCalendarBehavior == null)
        {
            return;
        }
        RadCalendar calendar = datePickerCalendarBehavior.Calendar;
        calendar.ShowFooter = true;
 
        CalendarStatusElement calendarStatusElement = calendar.CalendarElement.CalendarStatusElement;
        calendarStatusElement.RightToLeft = true;
        calendarStatusElement.LabelElement.Visibility = ElementVisibility.Hidden;
     
        calendarStatusElement.TodayButton.Text = Resources.strToday;
        calendarStatusElement.TodayButton.Click += (sender, args) =>
        {
            calendar.SelectedDates.Clear();
            this.Value = DateTime.Today;
            datePickerCalendarBehavior.PopupControl.HideControl();
        };
 
        calendarStatusElement.ClearButton.Text = Resources.strClear;
        calendarStatusElement.ClearButton.Click += (sender, args) =>
        {
            this.SetToNullValue();
            datePickerCalendarBehavior.PopupControl.HideControl();
        };
    }
 
    [Browsable(false)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
    public override DateTimePickerFormat Format
    {
        get { return base.Format; }
        set { base.Format = value; }
    }
}

Now I want to use it in RadGridView as an editor. I have tried to use some concepts from http://www.telerik.com/help/winforms/gridview-editors-using-custom-editors.html, but with no success.
 How can I achieve the desired functionality?

Hello Patryk,

Thank you for contacting Telerik Support.

In order to replace the default RadDateTimeEditor in RadGridView, you should create derivative of the desired editor as it is described in our Using custom editors help article. Following this approach, you can replace any editor with a custom one:
public Form1()
{
    InitializeComponent();
 
    radGridView1.EditorRequired += radGridView1_EditorRequired;
}
 
private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
{
    if (e.EditorType == typeof(RadDateTimeEditor))
    {
        e.Editor = new CustomDateTimeEditor();
    }
}

public class CustomDateTimeEditor : RadDateTimeEditor
{
    public CustomDateTimeEditor() : base()
    {
        InitializeComponent();
    }
 
    private void InitializeComponent()
    {
        ((RadDateTimePickerElement)this.EditorElement).Format = DateTimePickerFormat.Short;
        InitializeFooter();
    }
 
    private void InitializeFooter()
    {
        RadDateTimePickerElement editorElement = this.EditorElement as RadDateTimePickerElement;
        RadDateTimePickerCalendar datePickerCalendarBehavior = editorElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
        if (datePickerCalendarBehavior == null)
        {
            return;
        }
        RadCalendar calendar = datePickerCalendarBehavior.Calendar;
        calendar.ShowFooter = true;
 
        CalendarStatusElement calendarStatusElement = calendar.CalendarElement.CalendarStatusElement;
        calendarStatusElement.RightToLeft = true;
        calendarStatusElement.LabelElement.Visibility = ElementVisibility.Hidden;
 
        calendarStatusElement.TodayButton.Text = "today";//Resources.strToday;
        calendarStatusElement.TodayButton.Click += (sender, args) =>
        {
            calendar.SelectedDates.Clear();
            this.Value = DateTime.Today;
            datePickerCalendarBehavior.PopupControl.HideControl();
        };
 
        calendarStatusElement.ClearButton.Text = "clear";//Resources.strClear;
        calendarStatusElement.ClearButton.Click += (sender, args) =>
        {
            ((RadDateTimePickerElement)this.EditorElement).SetToNullValue();
            datePickerCalendarBehavior.PopupControl.HideControl();
        };
    }
 
    [Browsable(false)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
    public DateTimePickerFormat Format
    {
        get
        {
            return ((RadDateTimePickerElement)this.EditorElement).Format;
        }
        set
        {
            ((RadDateTimePickerElement)this.EditorElement).Format = value;
        }
    }
}

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