Problem Negative number in android.

[Hong Quang Hung]

Version 19.1.0.59

The negative number is delete a minus when lost focus the control. If I type the minus before typing the muber it will be ok. But if I type it at the last the bug appear.

My code:

    var format = "### ##0";

            var decimalSeparate = ".";

            var groupSeparate = " ";

            var maxDigits = format.Contains(decimalSeparate) ? format.Length - format.IndexOf(decimalSeparate) - 1 : 0;

            var range = Math.Pow(10, format.Remove(decimalSeparate).Remove(groupSeparate).Length - maxDigits) - 1 / Math.Pow(10, maxDigits);

            var numberGroupSizes = format?.Split(decimalSeparate[0])[0].Split(groupSeparate[0]).Select(x => x.Length).Reverse().ToArray();

            var s = new StackLayout { Spacing = 0 };

            var n = new SfNumericTextBox

            {

                HeightRequest = 50,

                HorizontalOptions = LayoutOptions.FillAndExpand,

                TextAlignment = TextAlignment.Start,

                ReturnType = ReturnType.Done,

                ParserMode = Parsers.Decimal,

                ClearButtonVisibility = Syncfusion.XForms.Editors.ClearButtonVisibilityMode.Never,

                ValueChangeMode = ValueChangeMode.OnLostFocus,

                MaximumNumberDecimalDigits = maxDigits,

                FormatString = format

            };

            if (DeviceInfo.Platform != DevicePlatform.Android || numberGroupSizes.Length > 1)

            {

                n.GroupSeparatorMode = GroupSeparatorMode.Always;

                n.EnableGroupSeparator = true;

            }

Thank you, I hope this bug will be fix as soon as possible.

Best regard

Hi Hong Quang Hung,

Greetings from Syncfusion.

Query: The minus when lost focus the control
We have checked the reported issue, and the issue is reproduced in XForms android, when set the GroupSeparatorMode is Always. Currently, we are validating the reported query and we will update the details on May 13, 2021.

Query: In the Android platform, When I type a number, the NumberGroupSeparator is a comma although I set n.Culture.NumberFormat.NumberGroupSeparator = " ".
The group separator will be changed based on the device's current culture. We can't set the culture through n.Culture.NumberFormat.NumberGroupSeparator.

Thanks your answer, with above code:

Q1: I replace ValueChangeMode = ValueChangeMode.OnKeyFocus. If I set Maximum = "555555", the number will be set 555.56 when unfocus this control. If I set Maximum = "555555.55" and type max value, it will be crash and show exception System.FormatException: 'Input string was not in a correct format.' The error is only in Android. It seem happen when the value > Maximum but event ValueChanged invokes. In IOS, the event not fire.

Q2: The group separator will be changed based on the device's current culture and it is comma. How to change it to space like format. ( I have set culture on IOS and it successed).

Q3: I update the control to v19.1.0.63, The minus when lost focus the control is not fixed. 

I hope Syncfusion reply my question and help me resolve with my problem.

Thanks,

Query: The group separator will be changed based on the device's current culture and it is comma. How to change it to space like format. ( I have set culture on IOS and it successed).

We would like to inform you that, you can change the group separator as space by using the below code snippet 

CultureInfo cultureInfo = new System.Globalization.CultureInfo("fr-FR"); 

cultureInfo.NumberFormat = new NumberFormatInfo()
{
NumberGroupSeparator = " "
};  

n.Culture = cultureInfo; 

 

Query: It seems to happen when the value > Maximum but event ValueChanged invokes. In IOS, the event not fire.
ValueChanged event is fired properly if the value is greater than or less than the maximum value.  We have prepared a sample for your requirement please have a sample from the below link
https://www.syncfusion.com/downloads/support/directtrac/general/ze/sample_(10)1907349370

Since we are not aware of your exact application scenario, we were not able to reproduce this at our end, can you please revert us by modifying the sample based on your application along with the replication procedure.

Thanks Syncfusion,

I am most graceful with your support for my problem. I will try this solution to my issue.

Query: It seems to happen when the value > Maximum but event ValueChanged invokes. In IOS, the event not fire. It Happens when format such as ### ##0.00.

Note: I set CurrentCulture and CurrentUICulture is new CultureInfo("en-US").

Hi Hong Quang Hung,

We can able to reproduce the "ValueChanged event not fired" problem when set the SfNumericTextBox ValueChangeMode is onLostFocus.  Can you please confirm whether you have faced this problem with this mentioned case (ValueChangeMode as onLostFocus) ?

Regards,
Sridevi S. 

[Hong Quang Hung]

In case ValueChangeMode as onLostFocus. It is perfect. App crash when I set OnkeyFocus and format is have decimal digit (### ###.00).

[Sridevi Sivakumar]

Hi Hong Quang Hung,

Query 1: ValueChanged event not fired
In your earlier update, you have mentioned “In IOS, the event not fire”. We have checked and ensured, SfNumericTextBox ValueChanged event is fired properly when set ValueChangeMode is OnkeyFocus. Please have video from the below link

Video link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/Video_(2)1638555671.zip

If you are facing the issue in OnkeyFocus mode,  please share the platform that you are using to reproduce the problem.

We have faced event not triggered in ValueChangeMode on LostFocus in second time: If I type a value greater than the Maximum value and then unfocus the control, the event is triggered. However, after clearing the value and repeating the operation, the event not triggered.

Can you please explain are facing the event not fired problem in ValueChangeMode OnkeyFocus or onLostFocus and share the issue reproducing platform also.

With the complete details, please create a separate incident or forum for better follow up for this query.

Query 2: App crash when I set OnkeyFocus and format is have decimal digit (### ###.00)

We can able to reproduce this crash and this issue related with your already reported scenario. We have already logged issue and mentioned the related issue and feedback link below, please find it.

I  think you understood my problem. 

Query 1: 

ValueChangeMode = ValueChangeMode.OnKeyFocus

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");

Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");

I mention "In IOS, the event not fire". In case value has been set a maximum Value and you keep type value continuative and The event fire in Android. But I mentioned Query 2 in Android  and I predict it by Query 1 (I appriciate the event in Android is not fired as IOS, I don't want you test this case). 

My apologies for giving you the wrong information.

Thanks,

Hi Sridevi Sivakumar,

Can you please confirm still are you facing a "ValueChanged event not fired" problem in iOS on key focus?

Answer:
It is not a problem in IOS. I never say that. I only said "In IOS, the event fired". The problem is Android, the event fire, I want this event not invoke. Therefore, you need test it in Android not IOS. Sorry, my language is not good to misunderstand. I just want explain the reason why the app crash in android. ( app crash issue in android platform)

Thank,
