DataFormDateEditor Date Format

[Rodrigo]

Hi,

using com.telerik.widget.dataform.visualization.RadDataForm in Xamarin Native Android app.

By Default, DataFormDateEditor has Date Format "MMM dd, YYYY" and First day of the week is Sunday.

How can I change date format to dd.MM.YYYY and First Day of the week to Monday?

Setting Thread.CurrentThread.CurrentCulture and Thread.CurrentThread.CurrentUICulture seems not to have any effect...

Regards,

Rodrigo

Hi Rodrigo,

The date format of the DataFormDateEditor is defined per the application Locale and I am afraid we do not provide means to specify it.

So, basically, you can change the application Locale, thus not taking into account the target device Locale.

Setting the application Locale on Android is a little bit tricky, I have tested the following snippet inside OnCreate method of your MainActivity which works:

var locale = new Java.Util.Locale("en", "GB"); // lang => en; region => GB
Java.Util.Locale.Default = locale;
var context = Application.Context;
context.Resources.Configuration.Locale = locale;

context.Resources.UpdateConfiguration(context.Resources.Configuration, context.Resources.DisplayMetrics);

The problem is it uses deprecated API, here are some discussions on StackOverflow on the matter that can help:

Let me know if I can assist with anything else.

Thank you very much,

that worked. Just a small note: if Android.App.Application.Context is used as per example - then Date Format is applied, but First day of the week stays Sunday. But if BaseContext is used then First Day of the week get set to Monday, as expected.
