I just need a simple ToolTip WPF style that displays multiple lines

Question

Because of all the noise from the fantasy, super, huge and blah blah blah blah, tooltips I can not find the answer.

I just need a simple style that sets TextWrapping="Wrap" and allows me to set the width.

One that duplicates an existing default style / style, but only word wraps.

Answer 1

 <Window.Resources> <Style TargetType="{x:Type ToolTip}"> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <TextBlock TextWrapping="Wrap" Text="{Binding}" /> </DataTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <Grid> <Rectangle Width="100" Height="100" Fill="Red"> <Rectangle.ToolTip> <ToolTip Width="100"> This is some text with text wrapping. </ToolTip> </Rectangle.ToolTip> </Rectangle> </Grid> 

This example assumes that you want to set the width for each use. If you want to set it as part of the style, add it to the TextBlock element.

This style prevents the tooltip from appearing on empty lines.

 <Style TargetType="ToolTip"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ToolTip"> <TextBlock Text="{TemplateBinding Content}" MaxWidth="400" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Content" Value=""> <Setter Property="Visibility" Value="Collapsed" /> </Trigger> </Style.Triggers> </Style> 

Or using the ContentTemplate:

 <Style TargetType="{x:Type ToolTip}"> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <StackPanel> <TextBlock Text="{Binding}" MaxWidth="400" TextWrapping='Wrap' /> </StackPanel> </DataTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Content" Value=""> <Setter Property="Visibility" Value="Collapsed" /> </Trigger> </Style.Triggers> </Style>
