windows phone 8.1开发:(消息弹出框)强大的ContentDialog
原文出自:http://www.bcmeng.com/contentdialog/
在应用开发中我们必不可少的会使用到消息框,windows phone8中的messagebox在windows phone8.1中变成了MessageDialog.使用方法大体相差不大.不过MessageDialog的功能过于简单,许多时候无法满足我们的实际需要.在windows phone 8.1中出现了ContentDialog,ContentDialog不仅可以选择半屏或者全屏展示,里面的内容还可以像一个XAML页面一样实现自定义.
下面我们通过代码和实际运行效果来看一下:
ContentDialog半屏:
private async void Button_Click(object sender, RoutedEventArgs e)//半屏 { ContentDialog dialog = new ContentDialog() { Title = "Download updates?", //标题 Content = "This update will clean the slate for Iron Man",//内容 FullSizeDesired=false, //是否全屏展示 PrimaryButtonText = "Yes, clean it",//第一个按钮内容 SecondaryButtonText = "No, Dont!" }; dialog.SecondaryButtonClick += dialog_SecondaryButtonClick;//第二个按钮单击事件 dialog.PrimaryButtonClick += dialog_PrimaryButtonClick; ContentDialogResult result = await dialog.ShowAsync(); if (result == ContentDialogResult.Primary) { } //处理第一个按钮的返回 else if (result == ContentDialogResult.Secondary) { }//处理第二个按钮的返回 } async void dialog_PrimaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args) { await new MessageDialog("您选择了第一个按钮").ShowAsync(); } async void dialog_SecondaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args) { await new MessageDialog("您选择了第二个按钮").ShowAsync(); }
ContentDialog全屏:
private async void Button_Click_1(object sender, RoutedEventArgs e)//全屏 { ContentDialog contentdialog = new ContentDialog(); contentdialog.Title = "编程小梦"; contentdialog.Content = "专注于windows phone应用开发"; contentdialog.PrimaryButtonText = "赞一个"; contentdialog.SecondaryButtonText = "顶一个"; contentdialog.FullSizeDesired = true; await contentdialog.ShowAsync(); }
ContentDialog自定义1:
<ContentDialog x:Class="ContentDialogDemo.ContentDialog1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:ContentDialogDemo" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Title="DIALOG TITLE" PrimaryButtonText="sign in" SecondaryButtonText="cancel" PrimaryButtonClick="ContentDialog_PrimaryButtonClick" SecondaryButtonClick="ContentDialog_SecondaryButtonClick"> <StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch"> <TextBox Name="email" Header="Email address"/> <PasswordBox Name="password" Header="Password"/> <CheckBox Name="showPassword" Content="Show password"/> <!-- 内容主体 --> <TextBlock Name="body" Style="{StaticResource MessageDialogContentStyle}" TextWrapping="Wrap"> <TextBlock.Text> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. </TextBlock.Text> </TextBlock> </StackPanel></ContentDialog>
调用方法:
ContentDialog1 contentDialog1 = new ContentDialog1(); //ContentDialog1是系统自带的内容对话框页面 await contentDialog1.ShowAsync();
ContentDialog自定义2:
<ContentDialog x:Class="ContentDialogDemo.ContentDialog2" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:ContentDialogDemo" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Title="小梦词典" PrimaryButtonText="关于" SecondaryButtonText="好评" PrimaryButtonClick="ContentDialog_PrimaryButtonClick" SecondaryButtonClick="ContentDialog_SecondaryButtonClick"<Grid > <GridView HorizontalAlignment="Center"> <GridViewItem Margin="5"> <Button Content="查词" Background="#FFC5246D" ></Button> </GridViewItem> <GridViewItem Margin="5"> <Button Content="翻译" Background="#FFEAC418" Name="translate" ></Button> </GridViewItem> <GridViewItem Margin="5"> <Button Content="生词" Background="#FFCB32DA" ></Button> </GridViewItem> <GridViewItem Margin="5"> <Button Content="关于" Background="#FF58E4B5" ></Button> </GridViewItem> </GridView> </Grid></ContentDialog>
调用方法和上面一样,最终运行效果如下:
