Resize when change visibility items

Hi! 

I have a  view whit syncfusion:SfAccordion and multiple Stacklayouts inside. At the button of accordion, I have two stacklayout not visible, like this: 

                                    <StackLayout IsVisible="{Binding MostrarCambio, Mode=TwoWay}" Orientation="Horizontal">

The problem is that the accordion is not readjusted. If I put a visible item it does not expand and if it is invisible it is not cropped.
 Can I force the height calculation after changing the visible label?

On the other hand, if the accordion is loaded as invisible, changing it to visible does not work. It does not expand.
Can these problems be solved? Thank you. REGARDS

Hi, 
  
Thank you for using Syncfusion products. 
  
We have checked the reported queries from our end. 
  
#Regarding If I put a visible item it does not expand and if it is invisible it is not cropped 
  
We would like to inform you that you can use DynamicSizeMode property for Accordion to resize the content/header.  
Please refer the DynamicSizeMode property from the following link, 
 
  
DynamicSizeMode  
Description  
Content  
Indicates that the SfAccordion.Content gets re-measured and layout when its size is updated at runtime.  
Header  
Indicates that the SfAccordion.Header gets re-measured and layout when its size is updated at runtime.  
None  
Indicates that the dynamic changes of SfAccordion.Header and SfAccordion.Content will not be considered.  
Default value is None.  
  
Please refer the following code snippet for your reference,  
  
<syncfusion:SfAccordion Grid.Row="1" ExpandMode="SingleOrNone" DynamicSizeMode="Content"> 
... 
  
Please let us know if this resolves the reported issue. 
  
#Regarding if the accordion is loaded as invisible, changing it to visible does not work 
  
We have checked the reported query at our side. We would like to inform you that you can handle the visibility of the AccordionItem by modifying the AccordionItems collection. We have already documented the same and you can find them from the following link,

Thanks for the response. 
#Regarding If I put a visible item it does not expand and if it is invisible it is not cropped 

I try DynamicSizeMode="Content". In Android works perfectly but not in iOS.  In iOS collapse and expand the SfAccordion, height adjust to content perfectly. That is, the height is not calculated automatically. This item not adjust when change this visibility MostrarDatosTitularLuz


#Regarding if the accordion is loaded as invisible, changing it to visible does not work 

When launching view with Accordion (x:Name="AcordeonGas") Invisible  and change visibility to visible, in Android show correctly but in iOS not.

It's a bug or the code is wrong? Thank you

I've got the same problem.

The accordion is invisible when the view renders, and then I trigger something that should make this appear.

On iOS it doesn't render at all if the starting point is invisible.

Do you have a suggested hack that I can use to get this to work? July is far too long away...
