Blinking effect in ShapeNode

Hi,

We have ShapeNodes in our Diagram. We are applying trigger on ShapeNode when "IsMouseOver" property is "true" and setting its "BitMapEffect" property to "bitmapeffect".

OuterGlowBitmapEffect bitmapeffect = new OuterGlowBitmapEffect();
           bitmapeffect.GlowColor = Color.FromRgb(255, 140, 000);
           bitmapeffect.GlowSize = 6;
           bitmapeffect.Noise = 0;
           bitmapeffect.Opacity = 1.0;

When mouse leaves from ShapeNode(quickly), shape node blinks for a moment. It seems that node is first hide and then visible again.

Could you please suggest on it? What could be the problem?

Thanks and Regards,
Anshul

Hi,

I could not make the nodes blink, can you send an example to support@mindfusion.eu?

Additionally, BitmapEffect is obsolete property and you should use Effect instead. There is no Effect class equivalent to the outer-glow BitmapEffect, but you can get something close enough using DropShadowEffect, e.g. try this:

var glowEffect = new DropShadowEffect();
glowEffect.Color = Color.FromRgb(255, 140, 000);
glowEffect.ShadowDepth = 0;
glowEffect.BlurRadius = 10;

I hope that helps,
Stoyan

Hi,

We are applying trigger on MouseOver property of ShapeNode and setting its Effect property to DropShadowEffect, but it is not working.

<Style TargetType="{x:Type d:ShapeNode}">
           <Style.Triggers>
               <Trigger Property="IsMouseOver" Value="True">
                   <Setter Property="Effect">
                       <Setter.Value>
                           <DropShadowEffect BlurRadius="10" Color="Aqua" Opacity="1" ShadowDepth="5" />
                       </Setter.Value>
                   </Setter>
               </Trigger>
           </Style.Triggers>
       </Style>

Let know the solution.

Thanks and Regards,
Anshul

The node might have a local value for this property and it is with higher priority than the trigger value. Try clearing it by calling node.ClearValue(EffectProperty) to see if the trigger will work.

I hope that helps,
