[英]How to fix “ The property is set more than once”?
在我的列表视图中,当我展开我的列表视图时,我想向许多控件显示,但是当我将 Isvisible 属性分配给 label 时,我收到此错误“属性“文本”显示不止一次“
<?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="CpoLogin.MainPage">
<ListView ItemsSource="{Binding Complains}"
HasUnevenRows="True"
Margin="40,80"
ItemTapped="ListView_ItemTapped">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout>
<Label Text="{Binding ComplainsTitle}"/>
<Label Text="Caller CNIC: 4220142488449"/>
<Label Text="Complaint Type: Emergency"/>
<Label Text="Notes: Gulshan-e-Iqal,Karachi"/>
<Label Text="Criminals Involved: 2"/>
<Label Text="Dead Count: 2"/>
<Label Text="Sub Type: Murder"/>
<Label Text="Criminal Appearance: 2"/>
<Label Text="Wounded Count: 2"/>
<Label Text="Vehicle Used: 2"
IsVisible="{Binding IsVisible}/>
<Button Text="Details"
IsVisible="{Binding IsVisible}"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ContentPage>

请替换以下代码
<Label Text="Vehicle Used: 2"
IsVisible="{Binding IsVisible}" />
您忘记关闭双引号,如果对您有帮助,请检查并接受答案。
对按钮使用内容而不是文本。
