    I am trying to set the value property in code on the DateTimePicker (Input mode is Time Picker). It looks like the value is being set properly but I never see anything displayed in the UI. I have tried to set the RadDateTimePicker.DateTimeText and that doesn't seem to work either. ???

    RadDateTimePicker dayEndTimePicker = new RadDateTimePicker();
                dayEndTimePicker.InputMode = Telerik.Windows.Controls.InputMode.TimePicker;
                dayEndTimePicker.MinWidth = 75.0;
                dayEndTimePicker.MaxWidth = 75.0;
                dayEndTimePicker.SelectionChanged += new SelectionChangedEventHandler(dayEndTimePicker_SelectionChanged);
                string endTime = GetScreenSettingValue("DayEndTime", "18:00:00", false);
                string[] endTimeSplit = endTime.Split(new Char[] { ':' });
                dayEndTimePicker.SelectedValue = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, Convert.ToInt32(endTimeSplit[0]), Convert.ToInt32(endTimeSplit[1]), Convert.ToInt32(endTimeSplit[2]));
                dayEndTimePicker.DateTimeText = dayEndTimePicker.SelectedValue.Value.ToShortTimeString();

    Hello Rod,

    I tried to reproduce the issue but couldn't, here is a sample code that represents how to declare a RadDateTimePicker with SelectedValue from the code behind:

    RadDateTimePicker radDateTimePicker = new RadDateTimePicker()
        InputMode = Telerik.Windows.Controls.InputMode.TimePicker,
        SelectedValue= new DateTime(2012, 6, 29, 14, 20, 0, 0)

    Hope this helps.

    All the best,
    the Telerik team

    I am updating the version of the controls from 2010 to 2020.
    The same happens to me with MVVM. But if I change the InputMode to "DatePicker" the control shows data.
    In the 2010 version this did not happen and the control showed data with both InputMode.

    Hello Enrique,

    I tested the scenario in a sample project, however the SelectedValue is displayed in the RadDateTimePicker when the InputMode is TimePicker. That is why I am attaching the project that I used for testing purposes. Can you check it out and see how it differs from the setup on your end?

    Should you need any further assistance, you can modify it in order to replicate the observed on your end behavior and send it back in a new support ticket (since project files cannot be attached to forum posts). This will allow me to investigate further and better assist you.
