Basic WPF ToolTip ExampleDrag a Button control from the toolbox and drop it. Add a ToolTip property to the button with a message you want to show on mouse hover of the button.
In this article we will see how we can Bind an Image to the Tooltip of an Image. Fire up Visual Studio 2008 and Create a WPF Application and name the project as ImageTooltipInWPF. Tooltip on the top as it's preview. So let's have a ListBox and then we will bind the images onto it.
Use the Placement property or ToolTipService. Placement attached property to place the ToolTip above, below, left, or right of the pointer. You can set the VerticalOffset and HorizontalOffset properties to change the distance between the pointer and the ToolTip.
The TextBlock control provides flexible text support for UI scenarios that do not require more than one paragraph of text. It supports a number of properties that enable precise control of presentation, such as FontFamily, FontSize, FontWeight, TextEffects, and TextWrapping.
This gives you really big tooltips in all places:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Page.Resources>
<Style x:Key="{x:Type ToolTip}" TargetType="{x:Type ToolTip}">
<Setter Property="FontSize" Value="24"/>
</Style>
</Page.Resources>
<Grid>
<Button Content="Hey" ToolTipService.ToolTip="Hey"/>
</Grid>
</Page>
If you want to change particular tooltip you can define style closer to that tooltip, or place fontsize directly in the tooltip:
<Button Content="Hey">
<ToolTipService.ToolTip>
<TextBlock FontSize="64" Text="Hey"/>
</ToolTipService.ToolTip>
</Button>
