    Is there a way to disable or make time unselectable in the Calendar's time pop window.

    My requirement is I have RadDateTimePicker control for From and To dates. When I select From date & time, the selectable date & time in To date-time control should be the value greater than or equal to From date-time value. 

    Currently I have achieved it partially using SelectableDateStart property. Using this property I can control only dates but not time.

    For example,

    I select From date & time as 15-07-2015, 11:30 respectively. Now in the To date-time control the selectable dates are 15-07-2015 and above. It won't allow the user to select date preceding 15-07-2015.

    But the Time preceding 11:30 should be made unselectable which I am unable to achieve.

    Can you please help me with this.


    I am new to this forum and to WPF development. I'm sorry If I missed out some standard of creating new thread in the forum.


    Thanks in advance.

    Hi Shoukat,

    You can use the StartTime property of RadDateTimePicker and set the desired time. If you want this time to be the same for each date that can be selected, this works out of the box. If you want to apply a particular starting time only on one day, you need to implement a custom logic that checks if the day is the desired one and sets a custom value for StartTime only for this day.

    You can do this in the EventHandler of the SelectionChanged event:

    private void picker_SelectionChanged(object sender, SelectionChangedEventArgs e)
               if ((DateTime)e.AddedItems[0] == new DateTime(2015, 07, 15, 00, 00, 00))
                   (sender as RadDateTimePicker).StartTime = new TimeSpan(11, 30, 00);
                   (sender as RadDateTimePicker).StartTime = new TimeSpan(00, 00, 00);

    More on the selection in RadDateTimePicker you can find here:

    Please note that the hours that precede the set StartTime value won't be visible.

    Hope this helps.
