Hi,

I used a TimePicker in RadGridView as editor control,

var culture = new CultureInfo("en-US") {DateTimeFormat = {ShortTimePattern = "HH:mm"}};
BindingTarget = RadDateTimePicker.SelectedTimeProperty;
return new RadDateTimePicker { SelectedTime = (TimeSpan)viewItemHolder[feature], InputMode = InputMode.TimePicker, TimeInterval = TimeSpan.FromMinutes(15), Culture = culture };

It seems if I select an item in its dropdown list via mouse clicking, it will lost focus and cause the editing row to commit immediately. If I select the item using keyboard (hitting enter), the TimePicker seems stay in focus.

I didn't notice this problem with RadDatePicker or RadDateTimePicker . Any idea what might go wrong here?

Hi Larry,

I test the described scenario with the latest release version and the explained behavior is not present there. So I assume you are using an older version and my suggestion would be to test the same scenario with the newest one and let me know if this helps.

Hope this will work for you. If you still observe the same behavior using the newest version I'll ask you to share some more details about the exact scenario.

Hello Kalin,

I am using RadTimePicker from version Q2 2014 and I am still getting this issue.

When I select a time say 6:15 and then I edit to change it to 6:18 and then Click on a Button, the Time value is not bound to the property AtTime in ViewModel.

XAML :
<telerik:RadTimePicker x:Uid="uxAtTimePicker" x:Name="uxAtTimePicker" Width="203" VerticalAlignment="Center" SelectedTime="{Binding AtTime, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">

ViewModel:

public TimeSpan? AtTime
{
get
{
return theAtTime;
}
set
{
theAtTime = value;
base.OnPropertyChanged("AtTime");
}
}

Best Regards,
Santhosh B

Hi Santhosh,

We aware of the explained issue and have it already logged in our Feedback portal. You can easily track its status on the following link:
http://feedback.telerik.com/Project/143/Feedback/Details/133215-selectedtime-property-of-timepicker-is-not-updated-correctly-when-manually-changi

However currently as a work around you can use RadDateTimePicker with InputMode TimePicker instead. You would need to bind the SelectedValue property to a DateTime? property in the ViewModel and will have to extract the Time from the SelectedValue in order to get the correct SelectedTime.

I apologize for any inconvenience caused. If you have any other questions let us know.

Regards,
Kalin
