我想显示一个内容对话框,其中包含比传统的主要和次要结果更多的内容。
The 内容对话框有 2 个内置按钮(主/辅助按钮),可让用户响应对话框。如果您希望有更多按钮让用户响应对话框,您应该可以通过在对话框内容中包含这些按钮来实现此目的。
以下是一个简单的示例,展示了如何创建和使用带有 3 个按钮的自定义对话框:
MyCustomContentDialog.xaml
<ContentDialog
x:Class="ContentDialogDemo01.MyCustomContentDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:ContentDialogDemo01"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
x:Name="dialog"
Title="Delete">
<!-- Content body -->
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" Margin="0,20">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="200" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Grid.ColumnSpan="3" Text="Delete file A?" Margin="5" />
<Button Grid.Row="1" Content="Yes" x:Name="btn1" Click="btn1_Click" Margin="5,0" Width="100" />
<Button Grid.Row="1" Grid.Column="1" Content="No" x:Name="btn2" Click="btn2_Click" Margin="5,0" Width="100" />
<Button Grid.Row="1" Grid.Column="2" Content="Cancle" x:Name="btn3" Click="btn3_Click" Margin="5,0" Width="100" />
</Grid>
</ContentDialog>
MyCustomContentDialog.xaml.cs
namespace ContentDialogDemo01
{
// Define your own ContentDialogResult enum
public enum MyResult
{
Yes,
No,
Cancle,
Nothing
}
public sealed partial class MyCustomContentDialog : ContentDialog
{
public MyResult Result { get; set; }
public MyCustomContentDialog()
{
this.InitializeComponent();
this.Result = MyResult.Nothing;
}
// Handle the button clicks from dialog
private void btn1_Click(object sender, RoutedEventArgs e)
{
this.Result = MyResult.Yes;
// Close the dialog
dialog.Hide();
}
private void btn2_Click(object sender, RoutedEventArgs e)
{
this.Result = MyResult.No;
// Close the dialog
dialog.Hide();
}
private void btn3_Click(object sender, RoutedEventArgs e)
{
this.Result = MyResult.Cancle;
// Close the dialog
dialog.Hide();
}
}
}
以下是显示自定义对话框并使用返回的自定义结果的代码:
private async void ShowDialog_Click(object sender, RoutedEventArgs e)
{
// Show the custom dialog
MyCustomContentDialog dialog = new MyCustomContentDialog();
await dialog.ShowAsync();
// Use the returned custom result
if (dialog.Result == MyResult.Yes)
{
DialogResult.Text = "Dialog result Yes.";
}
else if (dialog.Result == MyResult.Cancle)
{
DialogResult.Text = "Dialog result Canceled.";
}
else if (dialog.Result == MyResult.No)
{
DialogResult.Text = "Dialog result NO.";
}
}
Here is the entire sample. Following is the output:
