Or condition, multitrigger

Sun, 17 Jun 2007 21:16:21 Z

Hi...

Why is there not a OrCondition? or better why is Condition sealed?

I'm trying to do something like this:

                            <Trigger Property="IsFocused" Value="True">
                                <Trigger.EnterActions>
                                    <BeginStoryboard>
                                        <DoubleAnimation To="1.0" Storyboard.TargetProperty="Background.Opacity" Duration="0:0:1"/>
                                    </BeginStoryboard>
                                </Trigger.EnterActions>
                                <Trigger.ExitActions>
                                    <BeginStoryboard>
                                        <DoubleAnimation To="0.0" Storyboard.TargetProperty="Background.Opacity" Duration="0:0:1"/>
                                    </BeginStoryboard>
                                </Trigger.ExitActions>
                            </Trigger>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Trigger.EnterActions>
                                    <BeginStoryboard>
                                        <DoubleAnimation To="1.0" Storyboard.TargetProperty="Background.Opacity" Duration="0:0:1"/>
                                    </BeginStoryboard>
                                </Trigger.EnterActions>
                                <Trigger.ExitActions>
                                    <BeginStoryboard>
                                        <DoubleAnimation To="0.0" Storyboard.TargetProperty="Background.Opacity" Duration="0:0:1"/>
                                    </BeginStoryboard>
                                </Trigger.ExitActions>
                            </Trigger>

But it does not work properly because they "overwrite" eachother... hope you know what I mean - my english is not that good

But anyway, I would like to do:

<MultiTrigger>
    <MultiTrigger.Conditions>
       <OrCondition>
          <Condition Property="IsFocused" Value="True"/>
          <Condition Property="IsMouseOver" Value="True"/>
       </OrCondition>
    <MultiTrigger.Conditions>
    <MultiTrigger.EnterActions>
       <DoubleAnimation To="1.0" Storyboard.TargetProperty="Background.Opacity" Duration="0:0:1"/>
    </MultiTrigger.EnterActions>
    <MultiTrigger.ExitActions>
       <DoubleAnimation To="0.0" Storyboard.TargetProperty="Background.Opacity" Duration="0:0:1"/>
    </MultiTrigger.ExitActions>
</MultiTrigger>

But is there a better way to do it?

Hello, I think you can use your MultiTrigger with "and condition". You can set the Conditions to meet when IsFocused and IsMouseOver are both false, and exchange the Storyboards in EnterActions and ExitActions with each other.

Yeah, I have tought about that, but it is rather complex :/

Here's something that might work for you, using a MultiTrigger:

Code Snippet

    <Page.Resources>
        <Style x:Key="StoryKey" TargetType="{x:Type TextBox}">
            <Setter Property="Background">
                <Setter.Value>
                    <SolidColorBrush Color="Red" Opacity="0" />
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <MultiTrigger>
                    <MultiTrigger.Conditions>
                        <Condition Property="IsFocused"   Value="true" />
                        <Condition Property="IsMouseOver" Value="true" />
                    </MultiTrigger.Conditions>
                    <MultiTrigger.EnterActions>
                            <BeginStoryboard>
                                <Storyboard>
                                    <DoubleAnimation
                                        Storyboard.TargetProperty   = "(TextBox.Background).(SolidColorBrush.Opacity)"
                                        To                          = "1"
                                        Duration                    = "0:0:0.5"
                                      />
                                </Storyboard>
                            </BeginStoryboard>
                    </MultiTrigger.EnterActions>
                    <MultiTrigger.ExitActions>
                            <BeginStoryboard>
                                <Storyboard>
                                    <DoubleAnimation
                                        Storyboard.TargetProperty   = "(TextBox.Background).(SolidColorBrush.Opacity)"
                                        To                          = "0"
                                        Duration                    = "0:0:0.5"
                                      />
                                </Storyboard>
                            </BeginStoryboard>
                    </MultiTrigger.ExitActions>
                </MultiTrigger>
            </Style.Triggers>
        </Style>
    </Page.Resources>

Thank you But in my example there will be more Multitriggers which is ogly, but I guess that's the only way...
