SfNumericTextBox TextColor cannot be set to Black

[Alex]

Hello,

I'm using SfNumericTextBox in Xamarin Forms and it looks like it does not set Black value to TextColor.

My input layout looks like this:

<inputLayout:SfTextInputLayout

                       Hint="{Binding AmountHint}"

                       HelperText="{Binding AmountHelperText}"

                       ErrorColor="Red"

                       HasError="{Binding Path=AmountHasError, Mode=TwoWay}"

                       ErrorText="{Binding Path=AmountErrorMessage, Mode=TwoWay}">

                       <numericBox:SfNumericTextBox

                          TextColor="Black"

                          Value="{Binding AmountValue, Mode=TwoWay}" />

</inputLayout:SfTextInputLayout>

When iOS runs in Dark mode - control will ignore TextColor="Black". At the same time if I set any other color - it work as expected.

I use 18.3.0.47 version.

I tried to use both direct setting of TextColor as above and DynamicResource as well - it works well unless I try to set it to black.

As a workaround that I use now is setting it not to Black (or #000000), but to #000001 - it looks almost as black for humans and it works.

Hi Alex,  

   

We are glad that your issue is resolved by your workaround solution.  

   

We have also checked reported issue in iPhone but not reproduced on our side. So, can you share the possible code example to replicate it at our end to replicate it and provide a possible solution earlier?  

  

For your information, find the result from our testing  

 

   

 

This will be helpful for us to validate the issue on our side further.

Hi Ramya,

Thanks a lot for checking and writing back. Maybe this issue appears in some specific cases. I would not say that there is something extraordinary that I use. Only thing - I use Prism framework, that's it.

Before posting this message I checked for a similar issues and seems that such behaviour occurs from time to time with other people as well. One example is here: https://www.syncfusion.com/forums/148219/rendering-issue-forcing-white-text - that gentleman solved it by setting color to blue and than to black programmatically. In my case I just used slightly modified color.

As you asked - I have uploaded full XAML code here: https://alex.ihnatusha.pro/downloads/sfExample.txt

The resource dictionary from where DynamicResource styles are loaded are here: https://alex.ihnatusha.pro/downloads/sfDynamicResource.txt

If I change #000001 to Black or #000000 in InputNumeric - colours will remain white.

Thanks for checking.

Alex

Hi Alex, 

 

Thanks for sharing your code snippet. 

 

Currently we are validating on this problem. We will update you the status to provide the possible source or sample solution on November 16, 2020.

Hi Alex, 

 

On further analysis, the reported problem occurred in the framework entry control when setting the dynamic resource text color using dark mode. So, we will check and fix the reported problem in SfNumericTextBox in volume 4 release which is expected to be rolled out in the month of December 2020.
