Change vertex background with trigger

Sep 14, 2010 at 11:32 AM

Hi there,

i've got a problem when i try to change the background color of a vertex (using the trigger -defined in the source of g#)

i changed the highlightTrigger so that now it becomes active when i press the mouse button (not when i step over a vertex)

and in these following lines i get the value of the new background color from a property inside a class of mine (that's because maybe i just want a red back color one time, then maybe a blue one or a green one..i simply update the HighlightedBackgroundColor property with the new one, so that it can be read every time i click ).

<Trigger Property="GraphSharp_Controls:GraphElementBehaviour.IsHighlighted" Value="true">
        <Setter Property="Background" Value="{Binding Path=(myNamespace:myClass.HighlightedBackgroundColor)}"/>

the problem is that i'm able to do this only once for every single vertex (tho every new color i choose is correctly passed to HighlightedBackgroundColor) : so when i click on a vertex the background will always use the first color the property had. It looks like the trigger is activated just the first time for every vertex.


any idea?
