Question

I have a list of objects as the item source for the datagrid. I also have buttons with tooltips but I want the tooltips to be “localize-able”/dynamic. I don’t want to explicitly add another property on the class of the objects (would be ugly) so instead, I want to create a string in the UserControl and do something like

public string ThisTag { get { return "someString"; } }

and on the xaml

<Button ...>
   <ToolTipService.ToolTip>
      <Tooltip Style={StaticResource ToolTipStyle} Tag={Binding Source=thisUserControl.ThisTag} />
...

the style

<Style x:Name="ToolTipStyle" TargetType="ToolTip">
   <Setter Property="Template">
       <Setter.Value>
           <ControlTemplate TargetType="ToolTip">
               <Grid>
                  <TextBlock Text="{TemplateBinding Tag}" Foreground="{StaticResource AnotherResource}"></TextBlock>
...

1. Is that possible or is there a similar simple way to bind to a property?
2. What would be the proper syntax to bind to the string?

Answer 1

I can’t quite make the Binding Path and ElementName style work so I settled to making a custom class like so

public class LocalizedDatagridButtonsTooltips
{
   public string TooltipOne { get { return SomeMethodToTranslate("This Phrase"); } }
   ...
}

create an instance of the class in the App.xaml (depends where the class is declared). “local” is declared on xaml.

<local:LocalizedDatagridButtonsTooltips x:Key="LocalizedTooltips"/>

Then setting the tag or whatever element that needs the string in the xaml (in my case, the Tag attribute needs the binding)

<Tooltip Tag="{Binding Source={StaticResource LocalizedTooltips}, Path=TooltipOne}" >

I got the solution from here:

these solutions also works for 4-5 (I think SL 5 has the “AncestorType” accr. dbaseman).
