The above mentioned issue in v18.104.22.168 was a bug which has now been taken care of internally, and the fixes will be available in the next release of Essential Suite.
For now, a workaround here would be to handle the DateTimePickerAdv''s GotFocus event as shown below :
this.dateTimePickerAdv1.GotFocus += new EventHandler(DateTimePickerAdv_GotFocus);
private void DateTimePickerAdv_GotFocus (object sender, EventArgs args)
this.dateTimePickerAdv1.Format = DateTimePickerFormat.Long;
this.dateTimePickerAdv1.Format = DateTimePickerFormat.Short;
Please refer to the modified sample
attached here that illustrates this workaround, and let me know if this works for you. Thanks for your feedback.
