I would like to know why if I insert a FlexGrid in an empty page it is correctly visible while if I insert it in a page where it is nested inside other elements, starting from a TabView I see only a white box. This code works:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage
x:Class="App1.MainPage"
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:c1="clr-namespace:C1.Xamarin.Forms.Grid;assembly=C1.Xamarin.Forms.Grid"
xmlns:local="clr-namespace:App1">
<ContentPage.Content>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="360" />
</Grid.RowDefinitions>
<c1:FlexGrid x:Name="grid"/>
</Grid>
</ContentPage.Content>
</ContentPage>
This doesn’t work:
<?xml version="1.0" encoding="utf-8" ?>
