The highlight is not applied when the control is not visible

I´m using Syntax Edit Control in a project with custom Language. However, when I modify the Text property in code behind and the Edit control is not visible in screen, after turn visible the syntax highlight is not applied and the text is black. After I change the text by keyboard, the highlight is applied  only on the row changed.

Are there a method of Syntax Edit control to force the highligth apply when I want (when the visibility of control changes)?

I take two printscreens to exemplify the problem:


After each row is modified by keyboard:

Hi Guilherme Siqueira, 

Greetings form Syncfusion. 
We have checked your reported query “The highlight is not applied when the control is not visible”. We would like to let you know that you can highlight the syntax by using the DocumentLanguage property. Please refer the below help documentation link 


Also, you can able to create Custom Language configurations to apply syntax highlighting and outlining. Please refer the below help documentation link. 


We hope the above solution helps. If not please share the below details that will be helpful for us to provide a prompt solution on this. 
1.If you are using DocumentLanguage property to highlight the syntax means please share the DocumentLanguage (like c or csharp etc..) 
2.Share the code example how you are using it.

Elakkiya

Hi Elakkiya,

I updated the package to version 18.40.39 by "Manage NuGet package..." and run the example project "TesteSyntaxEdit_bf10a80.zip" that I sent you on February 9, 2021, but the same issue is present. I downloaded the package nuget by your link and install from nupkg file in my hd but de issue persists.

Am I doing something wrong to install the package? Could you verify that the package is correct?
