WPF Binding without path with converter, update

Question

I have a binding without path using a converter. This is because the converter will use many properties of the object to build the text for the tooltip. But when one property ch

One possible workaround is:

Give your object a ItSelf property (or other name) like:

public Object ItSelf
{
    get { return this; }
}

Instead of binding

{Binding Converter={StaticResource TooltipConverter}}

use

{Binding ItSelf, Converter={StaticResource TooltipConverter}}

Then you raise OnPropertyChanged for ''ItSelf'' for every property. So you can signal an update for the whole object whenever it was used in a binding.

public DateTime Start
{
    get { return this.start; }
    set { this.start = value; OnPropertyChanged("Start"); OnPropertyChanged("ItSelf");
}

I got this to work a bit faster but would like to test out AttachedBehavior for this like stated by @AnatoliiG so I will accept an answer later.
