如何在 Silverlight 中为每个(动态)列表框项目设置多行工具提示
我想在 Silverlight 中为 ListBox 中的每个项目设置一个包含多行的工具提示。
在 XAML 中,我有一个列表框和一个按钮:
<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# 中,
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;
}
}
我想为每个项目显示年龄作为我的工具提示。
编辑:好的,这是仅将 AGE 显示为工具提示的解决方案。那是一行/排。
<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>
但是如果我想显示 2 行工具提示怎么办?类似于:
Name: Name1
Age: 1
编辑:3 行,2 列。我还添加了 public String Comment { set;得到; 。
<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>
但是仍然有一个问题 注释可以短也可以长,所以我想使注释的行/行/空间可变,否则文本将被切断。
I would like to set in Silverlight for each item in a ListBox a tooltip with many rows.
In XAML i have a listbox and a button:
<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">
in 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;
}
}
I would like to show for each item the Age as my tooltip.
Edit: Ok, this is the Solution for showing only AGE as tooltip. That is one Line/Row.
<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>
But what if i want to show a Tooltip with 2 Lines? something like:
Name: Name1
Age: 1
Edit: 3 rows, 2 columns. i also added public String Comment { set; get; } 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>
But there is stil a problem. The comment can be short or long, so i would like to make the ROWS/LINES/SPACE for Comment to be variable or else Text is cut off.

您可以对工具提示内容使用任何控件:
另一种可能性是使用转换器,它返回由
\r\n
Name 和Age
>。You can use any controls for tooltip content:
Other possibility would be to use a converter, that returns the
Name
andAge
separated by\r\n
.
