tooltip font in wpf
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>
