我想在Silverlight中爲ListBox中的每個項目設置一個包含許多行的工具提示。如何爲Silverlight中的每個(動態)列表框項目設置工具提示
在XAML中,我有一個列表框和一個按鈕:
<ListBox Height="100" HorizontalAlignment="Left" Margin="24,136,0,0" Name="listBox1" VerticalAlignment="Top" Width="109" ItemsSource="{Binding}">
<Button Content="Add" Name="button_add" VerticalAlignment="Top" Width="118" Click="add_Click">
在C#
private void button_add_Click(object sender, RoutedEventArgs e)
{
ObservableCollection<Person> obs1 = new ObservableCollection<Person>();
obs1.Add(new Person(){Name="Name1", Age=1});
obs1.Add(new Person(){Name="Name2", Age=2});
listBox1.ItemsSource = obs1;
// This Line of Code MUST NOT BE USED!! listBox1.DisplayMemberPath = "Name";
}
public class Person
{
public String Name { get; set; }
public int Age { get; set; }
public override string ToString()
{
return Name;
}
}
我想顯示每個項目的年齡爲我的提示。
編輯:好的,這是隻顯示年齡爲工具提示的解決方案。這是一行/行。
<ListBox Height="100" HorizontalAlignment="Left" Margin="24,136,0,0" Name="listBox1" VerticalAlignment="Top" Width="109" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" ToolTipService.ToolTip="{Binding Age}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
但是如果我想顯示2行的工具提示呢?例如:
Name: Name1
Age: 1
編輯:3行,2列。我還添加了公共字符串註釋{set;得到; } to class Person
<ListBox Height="100" HorizontalAlignment="Left" Margin="24,136,0,0" Name="listBox1" VerticalAlignment="Top" Width="109" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<ToolTipService.ToolTip>
<ToolTip>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="20"></RowDefinition>
<RowDefinition Height="20"></RowDefinition>
<RowDefinition Height="40"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="80"/>
<ColumnDefinition Width="250"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Name: " Grid.Row="0" Grid.Column="0" />
<TextBlock Text="{Binding Name}" Grid.Row="0" Grid.Column="1"/>
<TextBlock Text="Age: " Grid.Row="1" Grid.Column="0"/>
<TextBlock Text="{Binding Age}" Grid.Row="1" Grid.Column="1"/>
<TextBlock Text="Comment: " Grid.Row="2" Grid.Column="0"/>
<TextBlock Text="{Binding Comment}" Grid.Row="2" Grid.Column="1" TextWrapping="Wrap" />
</Grid>
</ToolTip>
</ToolTipService.ToolTip>
<TextBlock Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
但還有一個問題。評論可以是短的或長的,所以我想讓評論的ROWS/LINES/SPACE可變,否則文本被截斷。
thx,我做了一個Grid。看看我的最後編輯 – Gero
