Problems with CanEdit / NullValue

[Frank Nanninga]

Hi,

I currently have two problems with the DateTimeEdit WPF control:

1.) When setting CanEdit=false, I still can do a textual edit - what I'd like to achieve is that the user can only pick a date via the picker control when activating the dropdown, how to achieve that?

2.) When setting a null value, the NoneDateText is not shown, instead I have two dots (the german date separators) - when changing the locale to english, I get the correct english ones (//) - please see attached picture. I assume that this behaviour is a bug? I can easily reproduce it by preparing an empty WPF project and injecting a DateTimeEdit with the appropriate parameters.

Could someone verify that?

Some more details:

Hi Frank

Thank you for contacting Syncfusion Support

Query 1: When setting CanEdit=false, I still can do a textual edit - what I'd like to achieve is that the user can only pick a date via the picker control when activating the dropdown, how to achieve that?

From your requirement, we come to know that you dont want to edit the DateTimeEdit and you want to pick the date only from the Picker control. In the DateTimeEdit control, when CanEdit is set as false, it allows the DateTime to edit the DateTimeField such as[Year,Month,Date]. So in order to achieve your requirement, you can handled it using the PreviewKeyDown event of DateTimeEdit control, so that you could not edit the value in the DateTime.

Please find the sample for the same.

Query 2: When setting a null value, the NoneDateText is not shown, instead I have two dots (the german date separators) - when changing the locale to english, I get the correct english ones (//) - please see attached picture. I assume that this behaviour is a bug? I can easily reproduce it by preparing an empty WPF project and injecting a DateTimeEdit with the appropriate parameters.

We have checked the reported query and we were able to reproduce the reported issue at our end. The fix for this reported issue would be included in the Volume 1, sp1 release 2018.
