UI not updated

[Ken]

Hi,

I have a RadTimePicker with its SelectedTime property bound to a view-model TimeSpan? property that looks like this:

public TimeSpan? Time
{
    get { return time; }
    set
    {
        if (value != null)
        {
             time = value;
        }
        NotifyPropertyChanged(...);
    }
}

So I'd like that when the user clears the input for the time picker the application actually restores the last value automatically. This should normally happen, since in the property setter I check for null and don't save the value, then raise the property changed event.

However, the input of the time picker stays blank! Can you tell me what I'm doing wrong here? The same approach works fine for a regular SL control (e.g. TextBox).

Thanks!

Interestingly enough, if I bind to the SelectedValue property, which is of type DateTime?, then it works as expected. So I guess there is a bug with SelectedTime?

Telerik, anyone?

Hello Adrian,

I would recommend you to use the SelectedValue property as it is the property designed to be bound with ViewModels. The SelectedTime property is exposed to be bound in the ControlTemplate of the DateTimePicker control to the Clock template part.
Though we will investigate the problem with the SelectedTime property as it is supposed to work correctly as well.

Hello Miroslav,

This is what I'm currently using. Would be nice to know if the problem with SelectedTime is identified and fixed though.

Thanks,
Adrian
