I have a xaml file where I wrote the title.
<?xml version="1.0" encoding="UTF-8"?>
<ContentView xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:d="http://xamarin.com/schemas/2014/forms/design"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
x:Class="TeenageClubWallet.Templates.Header">
<StackLayout>
<Label Text="Header!" />
</StackLayout>
I want to use this xaml file as a header in other xaml files. Here's an example. I'm trying to include it to another xaml file:
I added a namespace: xmlns:template="clr-namespace:TeenageClubWallet.Templates"
The "template" tag is now used to include file:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:d="http://xamarin.com/schemas/2014/forms/design"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
x:Class="TeenageClubWallet.Statistics"
xmlns:template="clr-namespace:TeenageClubWallet.Templates">
<ContentPage.Content>
<template:Header/>
<StackLayout>
<Label Text="Content!" />
</StackLayout>
</ContentPage.Content>
The visual studio shows the error: "Error XLS0501 The property 'Content' is set more than once."
How can I include content from one xaml file to another xaml file ?
In this example ContentPage
has two elements - template:Header
and StackLayout
and only one is allowed.
That is the cause of this problem. I haven't gone deeper in evaluating if there are further problems, but in the case they exist and you can't resolve them you should ask a new question.
I fixed it
To fix this, you need to insert the <template:Header/>
tag inside the <StackLayout>
tag.
Below is the full code:
<?xml version="1.0" encoding="utf-8" ?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:d="http://xamarin.com/schemas/2014/forms/design" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="TeenageClubWallet.Statistics" xmlns:template="clr-namespace:TeenageClubWallet.Templates"> <ContentPage.Content> <StackLayout> <template:Header/> <Label Text="Content!" /> </StackLayout> </ContentPage.Content>
