Can't change AM/PM from keyboard

[Davide]

I'm trying to use the RadMaskedDateTimeInput control, using a mask of "g", which provides date and time input with the AM/PM indicator. The AM/PM indicator can be changed using the up/down arrows when SpinMode is enabled but there is no way to change the AM/PM value using the keyboard. Do you have any solution or it is impossible for this component to do this?

Thx in advance

Hi,

Could you please clarify what you have in mind when you say:"The AM/PM indicator can be changed using the up/down arrows when SpinMode is enabled"? Which arrows you refer to?

Also, you are allowed to use the arrow keys of the keyboard to change the AP/PM selector. You can see this behavior in our QSF demo after changing the Mask to "g".

Hi Pavel ... 

In the RadMaskedDateTimeInput i'm displaying only the time as shown in the image 

For the hours, minutes and seconds i can edit them  but this cannot be done for the AM/PM value. I was asking if there is any way to be able to set this value from the keyboard typing A o P

Thx in advance

Hi Davide,

In order to change the AM with PM when the "p" key is pressed you can do these steps:
1. Subscribe to the KeyDown event of the control
2. Add 12 hours to the current Value
If you need the opposite, you can subtract 12 hours when the "a" key is pressed.

You can use this code as starting point:

private void RadMaskedDateTimeInput_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.A)
    {
        DateTime fullValue = (DateTime)(sender as RadMaskedDateTimeInput).Value;
        if (fullValue.Hour >= 12)
        {
            (sender as RadMaskedDateTimeInput).Value = new DateTime(fullValue.Year, fullValue.Month, fullValue.Day, fullValue.Hour - 12, fullValue.Minute, fullValue.Second);
        }
    }
    if (e.Key == Key.P)
    {
        DateTime fullValue = (DateTime)(sender as RadMaskedDateTimeInput).Value;
        if (fullValue.Hour <= 12)
        {
            (sender as RadMaskedDateTimeInput).Value = new DateTime(fullValue.Year, fullValue.Month, fullValue.Day, fullValue.Hour + 12, fullValue.Minute, fullValue.Second);
        }
    }
}
