Hi,

I’m trying to wrap the Scichart surface in XF. I’ve used native views as recommended in documentation and there is no problem when the SciChartSurface is the only element in a ContentPage, but when the surface is placed inside a layout or merged with any other element, then is not rendering.

Do you know why is this happening and how can I merge XF controls and SciChartSurface(s) in a ContentPage or any Layout?

1: This is rendering without problem

    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:SciChartForms"
             xmlns:localAndroid="clr-namespace:SciChartForms.Droid"
             x:Class="SciChartForms.MainPage">
    <localAndroid:Stripchart />
</ContentPage>

2: This is not rendering:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:SciChartForms"
             xmlns:localAndroid="clr-namespace:SciChartForms.Droid"
             x:Class="SciChartForms.MainPage">
    <StackLayout Margin="20">
        <Button Text="adafsd"/>
        <localAndroid:Stripchart/>
    </StackLayout>
</ContentPage>

Thanks in advance!

PS: I’ve also tried with custom renderer obtaining the same result.

Hi Antonio,

Have you tried to set Horizontal/VerticalOptions for you custom View. It seems to work in this case:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         xmlns:local="clr-namespace:FormsSandbox"
         xmlns:customViews="clr-namespace:scichartshowcase.CustomViews;assembly=FormsSandbox.Android"
         x:Class="FormsSandbox.MainPage">
  <StackLayout Margin="20">
    <Button Text="Label"/>
    <customViews:SciChartSurfaceView x:Name="sampleSurface" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"/>
  </StackLayout>

</ContentPage>

Best regards,
Yura

I tried that with the native view and got a xaml parse exception:

Xamarin.Forms.Xaml.XamlParseException: Position 9:34. Cannot assign property "HorizontalOptions": Property does not exists, or is not assignable, or mismatching type between value and property

I’ve just tried with the custom renderer and in this case is working, thanks!
