Time Picker in DateTimePicker do not affect ReadOnly property

[Zan]

Hello Telerik Team,

I'm using DateTimePicker as follow,

radDateTimePicker1.DateTimePickerElement.ShowTimePicker = true;
radDateTimePicker1.Format = DateTimePickerFormat.Custom;
radDateTimePicker1.DateTimePickerElement.CalendarSize = new Size(330, 250);
radDateTimePicker1.ReadOnly = true;

 

Time value in EditBox cannot edit. ReadOnly property working ok.

But Time value can be changed from dropdown's picker.

How can I fix this issue.

Hi AungKo,

Thank you for writing.

Indeed the reported behavior can be considered an issue and I have logged it on our feedback portal, here: FIX. RadDateTimePicker - setting the ReadOnly property on the control is not reflected in the time picker if it is shown by setting the ShowTimePicker property to true. I have updated your Telerik points for the report. Additionally, you can subscribe to the item and be updated with all of its status changes. 

We will do our best to include the fix in the R1 2018 release. Until then you can use the workaround below: 

this.radDateTimePicker1.DateTimePickerElement.ShowTimePicker = true;
this.radDateTimePicker1.Format = DateTimePickerFormat.Custom;
this.radDateTimePicker1.DateTimePickerElement.CalendarSize = new Size(330, 250);
this.radDateTimePicker1.ReadOnly = true;

RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
calendarBehavior.TimePicker.TimePickerElement.ReadOnly = true;

I hope this helps. Should you have further questions please do not hesitate to write back.
