After going through the whitepaper for Blendables, I discovered a way to implement a trigger without using the conventional WPF trigger. Confused? Check out the markup below:
<Grid>
<
Rectangle Grid.Row="2" RadiusX="2" RadiusY="2" Height="100" Width="200" Stroke="Black" Fill="Olive"Opacity="{blendables:EvalBinding [{Self}.IsMouseOver] ? 1 : 0.7}"/> </Grid>
EvalBinding adds a lot of power to WPF databinding. Keep up the good work Jonathan!!
Here is a sample.
Note: You need to download and install Blendables for this sample to work.
