I have a style for a ListViewItem control:
<EventTrigger RoutedEvent="ListViewItem.MouseEnter">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="BitmapEffect.Opacity"
From="0.0" To="1.0" Duration="0:0:0.5" AutoReverse="False" SpeedRatio="2" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="ListViewItem.MouseLeave">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="BitmapEffect.Opacity"
From="1.0" To="0.0" Duration="0:0:0.5" AutoReverse="False" SpeedRatio="2" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
I want to when mouse is over a ListViewItem, border of i开发者_JAVA技巧tem appearing slowly and when mouse leave it, border effect disappear, But i get this error when mouse goes to leave item:
Cannot resolve all property references in the property path 'BitmapEffect.Opacity'. Verify
that applicable objects support the properties.
Note that when i use only first EventTrigger
which routed to ListViewItem.MouseEnter
, program works correct! but it has not a good view!
I'm using OuterGlowBitmapEffect!
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="BitmapEffect">
<Setter.Value>
<OuterGlowBitmapEffect GlowColor="SkyBlue" GlowSize="20" />
</Setter.Value>
</Setter>
<Setter Property="Foreground" Value="Black" />
</Trigger>
I was trying with BitmapEffect, it is working fine as your above code.
<Style x:Key="ListBoxItemStyle1" TargetType="{x:Type ListBoxItem}">
<Setter Property="BitmapEffect">
<Setter.Value>
<OuterGlowBitmapEffect GlowColor="Blue" GlowSize="5" />
</Setter.Value>
</Setter>
<Style.Triggers>
<EventTrigger RoutedEvent="ListViewItem.MouseEnter">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="BitmapEffect.Opacity"
From="0.0" To="1.0" Duration="0:0:0.5" AutoReverse="False" SpeedRatio="2" />
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
<EventTrigger RoutedEvent="ListViewItem.MouseLeave">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="BitmapEffect.Opacity"
From="1.0" To="0.0" Duration="0:0:0.5" AutoReverse="False" SpeedRatio="2" />
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
</Style.Triggers>
</Style>
