sfnumericupdown and comma as a decimal digits delimiter


i can't say for sure when it changes but sfnumericupdown stops accepting comma as a decimal separator, at lease in ru-RU culture , it just strips comma out and send for instance 55 instead of 5,5 to binded control
i am sure it works earlier , but last days i updated 
visual studio to 2019
xamarin.forms to
your controls to

xaml code 

with ru-RU culture (on android samsung s7 , android 8.0 ) it shows point on a keyboard, accept input as point , but in binded property i receive data with point stripped out
i tried to set manually culture for control like 
tbWeight.Culture = System.Globalization.CultureInfo.CurrentCulture;
with ru-RU, it still show point on a keyboard, but didn't accept it entered

how can i fix this ?


update: downgrade to solved this.

Hi Ilya, 
Sorry for the inconvenience caused.  
Query 1: At lease in ru-RU culture, it just strips comma out and send for instance 55 instead of 5,5 to binded control. 
We have tried to replicate the reported issue at our end by created a sample with the provided information that you mention on your last update, we are afraid that, we are not able to reproduce the issue at our end. 
Query 2: Comma key is not visible on the Samsung keyboard. 
We have tried to reproduce the reported issue in the frame work “Entry” control also and that reported issue arises. Already there is an issue in the frame work that the decimal separator key (comma) is not shown in the keyboard in SAMSUNG devices. Could you please check the below link? 
Frame work bugs:  
Query 3: In ru-RU, it still shows point on a keyboard, but didn't accept it entered 
The Russian is comma culture and it doesn’t accept the dot as the separator and it is behavior and it’s not an issue. 
We are not able to reproduce this issue at our end, so can you please revert us by modifying the sample based on your application along with replication procedure. This will be helpful for us to investigate further and provide you a better solution at the earliest.

i downloaded your sample but it is not about sfnumericupdown control, it is about sfnumerictextboxt, which is not working on samsung devices with comma as a decimal separator . i found this information somewhere on your forum that is why switched to sfnumericupdown control

i will try to explain.
yes, there is a bug on samsung devices where numeric keypad contains point delimiter on numeric keyboard even if current culture use comma as delimiter

you sfnumericupdown control up to version accept point as delimiter and (i think) correctly changed it to comma (if need be) before output.
so, your control (up to version ) may be used as a workaround for samsung bug ;)

versions higher then accept dot as delimiter but strips it out when outputing value .. e.g. if you enter 1.2 , you will get the value "12"

so, the real question is, is it possible to restore this behaviour (change point from input to comma in output as it was up to or i need to stick with this version and look for another solution ?

Hi Ilya, 
Sorry for the inconvenience caused.  
While Setting the CultureInfo as ru-RU, keyboard will have point, but the control will not accept it. This is our expected behavior.  
However, will consider the improvement in the control to allow dot as value and after un-focusing the both the UI and value updated with comma. We have logged an improvement task and you can track that by using the below link. 
We will include this fix in the upcoming Volume 1, SP 1 release which is scheduled to rolled out on mid of May 2019. We appreciate your patience until then.

Hi Syncfusion-Team,

I also have the issue you wrote "Comma key is not visible on the Samsung keyboard." and have found a workaround for xamarin <entry>  with a custom dependency (https://github.com/xamarin/Xamarin.Forms/issues/1898#issuecomment-432539426)

Do you have also a fix or a workaround for your SfNumericTextBox? Its very important for our client to put in commas.

Thank you!

Hi Maria, 
We have checked the issue “Comma key is not visible on the Samsung keyboard” using the provided reference link but we are afraid that we are not able to get the comma key in the Samsung S6 device even with Entry control itself. Also, the provided solution does not seem to be generic.    
So, we would suggest you use the improvement that allow dot as comma separator for the culture which is based on Azerty keyboard. But the value will be updated with comma after the control is unfocussed. This improvement has been moved in our Volume 1 2019 SP1 release v (feedback link). We hope this improvement may fulfil your requirement. 
Please let me know if you need further assistance on this.

I had the same experience as Ilya with SfNumericUpdown:
On 17.2.x the comma is stripped out (e.g. if you enter 1.2 , you will get the value "12"). 
When I downgrade to it works well. 

Furthermore "return key" does not trigger the "valuechanged event". I have to unfocus the control
to update the value. On this also works well.

I use CultureInfo "de-DE" but it also dont work on "en-US".

Best regards,
