【问题描述】:
我想为文本框定义一个样式,并在我想绑定到相应样式所适用的属性的样式内。像这样的:
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="True">
<Setter Property="ToolTip">
<Setter.Value>
<TextBlock Text="{Binding ????Bind to the textbox TEXT property????}">
</TextBlock>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
这可能吗?
这里是完整的窗口:
<Window x:Class="StyleBinding.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:StyleBinding"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Window.Resources>
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="True">
<Setter Property="ToolTip">
<Setter.Value>
<TextBlock Text="{Binding Text, RelativeSource={RelativeSource Self}}"/>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<Grid>
<TextBox HorizontalAlignment="Left" Height="34" Margin="235,140,0,0" TextWrapping="Wrap" IsEnabled="True"
Text="Just a simple text" VerticalAlignment="Top" Width="284">
</TextBox>
</Grid>
</Window>
