RichTExtEditor throws NullReferenceException when adding or editing hyperlink information

Hi, please find the below repro steps for this problem:
  • In RichTextEditor, select a text (optional step). 

  • Click on the hyperlink button in the toolbar: the "Insert Link" popup appears.

  • Then either click on the entry below "URL" or the one below "Display text".

  • Both throw a NullReferenceException. It is impossible to enter anything.
This happens on Xamarin Forms with version 17.4.0.55 of the control.

The markup is pretty straightforward:

                <richtexteditor:SfRichTextEditor VerticalOptions="FillAndExpand" 
                                             x:Name="textEditor"
                                             Text=""
                                             PlaceHolder="Enter some text"
                                             HeightRequest="350"
                                             />

Thank you for your support

Hi Gary, 
Thank you for contacting Syncfusion support. 
The mentioned issue “Hyperlink option crash on SfRichTextEdtior” works as expected from our side. We have prepared a sample based on the mentioned requirement, which can be downloaded from the below link. 
Kindly provide us the detailed information about the issue reproducing scenario, Xamarin forms version used at design level or modify the provided sample to reproduce the exact scenario which will be helpful for us to provide a prompt solution at earliest.

Hi Devaraj,

Thanks for your answer.

The problem actually happens on Android Pie (v. 9) in those conditions chen using a xamarin shell application.

It disappears when removing the code "Window.SetSoftInputMode(Android.Views.SoftInput.AdjustResize);" from MainActivity.cs, but when doing that it is now the Syncfusion Autocomplete that does not work as excepted: the suggestion popup no longer shows up. 

So that solution is not acceptable, as many components require this line of code to be there.

Regards, 
Gary

Hi Gary, 
Thank you for the update. 
We have enabled SoftInputKey in MainActivity class to place the toolbar in appropriate position while raising the keypad from device. Also, we did not suggest removing the SoftInputKey from our end. We have prepared a video illustration based on the mentioned information which can be downloaded from the below link. 
Kindly provide us details information about the exact issue reproducing scenario or modify the provided sample to reproduce the issue which will be helpful for us to provide a prompt solution at earliest.

Hi Devaraj,

I attached a sample solution reproducing the problem.
 
It was done on Microsoft Visual Studio Community 2019 by creating a mobile application (Xamarin forms) and then chosing the "Shell" template.

The rich text editor has been added on the About Page (Views\AboutPage.xaml).


The problem occured on a Honor 10 mobile phone, did not try on an emulator but it might also happen there.

Hi again Devaraj, 

I was not sure whether the file was correctly attached so I attached it again in this post.

Best regards,
Gary
