UWP gridview项目选择样式

本文介绍了UWP gridview项目选择样式的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想更改gridview项目的选择样式或颜色。当选择一个项目时，我想显示较粗的边框或高光颜色或任何类型的更改。什么是最简单的方法来实现这一点

解决方案

请检查这个例子：

< Page x：Class =App3.MainPage xmlns =schemas.microsoft/winfx/2006/xaml/presentation xmlns：x =schemas.microsoft/winfx/2006/xaml xmlns：d =schemas.microsoft/expression/blend/2008 xmlns：local =using：App3 xmlns：mc =http：//schemas.openxmlformats / markup-compatibility / 2006 mc：Ignorable =d> <网格> < ListView x：Name =MyList> < ListView.ItemTemplate> < DataTemplate> < Grid x：Name =MyGrid> < TextBlock Text =Test1/> < / Grid> < / DataTemplate> < /ListView.ItemTemplate> < / ListView> < / Grid>

我填写清单：

保护覆盖无效OnNavigatedTo（NavigationEventArgs e） { base.OnNavigatedTo（e）; MyList.SelectionChanged + = MyList_SelectionChanged; var list = new List< string>（）; list.Add（1）; list.Add（2）; MyList.ItemsSource = list; }

最后，我得到选定的项目，然后更改背景

private void MyList_SelectionChanged（object sender，SelectionChangedEventArgs e） { var item = MyList.ContainerFromItem（e .AddedItems.FirstOrDefault（））; var selectedItem = item作为ListViewItem; if（selectedItem！= null） { var grid = selectedItem.ContentTemplateRoot as Grid; grid.Background =新的SolidColorBrush（Colors.Yellow）; } }

如果您看到我对此属性使用ContentTemplateRoot，则可以访问我的ItemTemplate的主容器。

I want to change the selection style or color of the gridview item. when an item is selected, I want to show a thicker border or a highlight color or any type of change like that. what is the simplest way to achieve this

解决方案

Please check this example:

I have my page like this:

<Page x:Class="App3.MainPage" xmlns="schemas.microsoft/winfx/2006/xaml/presentation" xmlns:x="schemas.microsoft/winfx/2006/xaml" xmlns:d="schemas.microsoft/expression/blend/2008" xmlns:local="using:App3" xmlns:mc="schemas.openxmlformats/markup-compatibility/2006" mc:Ignorable="d"> <Grid> <ListView x:Name="MyList"> <ListView.ItemTemplate> <DataTemplate> <Grid x:Name="MyGrid"> <TextBlock Text="Test1" /> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> </Grid>

I fill my list:

protected override void OnNavigatedTo(NavigationEventArgs e) { base.OnNavigatedTo(e); MyList.SelectionChanged += MyList_SelectionChanged; var list = new List<string>(); list.Add("1"); list.Add("2"); MyList.ItemsSource = list; }

Finally I get the selected item and I change the background

private void MyList_SelectionChanged(object sender, SelectionChangedEventArgs e) { var item= MyList.ContainerFromItem(e.AddedItems.FirstOrDefault()); var selectedItem = item as ListViewItem; if (selectedItem != null) { var grid = selectedItem.ContentTemplateRoot as Grid; grid.Background = new SolidColorBrush(Colors.Yellow); } }

If you see I use ContentTemplateRoot with this property I have access to the principal container of my ItemTemplate.
