您可以在组框的知名度绑定到它的孩子们的知名度？ [英] Can you bind the visibility of a GroupBox to the visibility of it's children?
问题描述
我有一个问题，试图获得一个分组框崩溃。我想一个分组框，如果所有它的孩子们晕倒，这将崩溃。
我已成功，为达到这一使用multibinding的属性，如下所示。
<预类=郎咸平的XML prettyprint-覆盖>
<&StackPanel的GT;
<分组框中>
< GroupBox.Visibility>
< MultiBinding
转换器={StaticResource的multiBoolOrToVis}
ConverterParameter ={X：静态Visibility.Collapsed}
>
<绑定路径=a_visible/>
<绑定路径=b_visible/>
< / MultiBinding>
< /GroupBox.Visibility>
< GroupBox.Header>
<标签内容=分组框/>
< /GroupBox.Header>
<&StackPanel的GT;
<标签
含量=A
能见度={绑定路径= a_visible，转换器= {StaticResource的boolToVis}}
/>
<标签
含量=B
能见度={绑定路径= b_visible，转换器= {StaticResource的boolToVis}}
/>
< / StackPanel的>
< /分组框中>
<网格和GT;
< Grid.ColumnDefinitions>
< ColumnDefinition WIDTH =*/>
< ColumnDefinition WIDTH =*/>
< /Grid.ColumnDefinitions>
<复选框
含量=可见的
Grid.Column =0
Grid.Row =1
=器isChecked{绑定路径= a_visible，模式=双向}
/>
将;复选框
含量=B可见
Grid.Column =1
Grid.Row =1
器isChecked ={结合路径= b_visible，模式=双向}
/>
< /网格和GT;
< / StackPanel的>
这个问题是我们希望能够以这种多次做，不用担心留下关闭绑定。所以我的问题是有这样做的一般，最好是在一种风格的任何方式。另一个要求是它必须是在XAML并不落后代码。
所以我理想的答案是一种风格，所以我可以在我的XAML以下。
<预类=郎咸平的XML prettyprint-覆盖>
<&StackPanel的GT;
<分组框样式=ChildrenVisibilityStyle>
< GroupBox.Header>
<标签内容=分组框/>
< /GroupBox.Header>
<&StackPanel的GT;
<标签
含量=A
能见度={绑定路径= a_visible，转换器= {StaticResource的boolToVis}}
/>
<标签
含量=B
能见度={绑定路径= b_visible，转换器= {StaticResource的boolToVis}}
/>
< / StackPanel的>
< /分组框中>
<网格和GT;
< Grid.ColumnDefinitions>
< ColumnDefinition WIDTH =*/>
< ColumnDefinition WIDTH =*/>
< /Grid.ColumnDefinitions>
<复选框
含量=可见的
Grid.Column =0
Grid.Row =1
=器isChecked{绑定路径= a_visible，模式=双向}
/>
将;复选框
含量=B可见
Grid.Column =1
Grid.Row =1
器isChecked ={结合路径= b_visible，模式=双向}
/>
< /网格和GT;
< / StackPanel的>
我已经看过这些问题，他们使我认为这是不可能的; 在ControlTemplate中结合，的 StackPanel的知名度，的边境知名度。
很抱歉，如果这已经回答过了。感谢您预先的任何答案/评论。
您可以使用 MultiDataTrigger 折叠分组框当儿童被倒塌
下面是一个工作的例子：
<&StackPanel的GT;
<分组框中>
< GroupBox.Header>
<标签内容=分组框/>
< /GroupBox.Header>
<&StackPanel的GT;
<标号x：名称=lbl_aCONTENT =A能见度={结合器isChecked，的ElementName = chk_a，转换器= {StaticResource的boolToVis}}/>
<标号x：名称=lbl_bCONTENT =B能见度={结合器isChecked，的ElementName = chk_b，转换器= {StaticResource的boolToVis}}/>
< / StackPanel的>
< GroupBox.Style>
<风格的TargetType =分组框>
< Style.Triggers>
< MultiDataTrigger>
< MultiDataTrigger.Conditions>
<条件绑定={结合能见度，的ElementName = lbl_a}VALUE =折叠/>
<条件绑定={结合能见度，的ElementName = lbl_b}VALUE =折叠/>
< /MultiDataTrigger.Conditions>
< MultiDataTrigger.Setters>
< setter属性=GroupBox.VisibilityVALUE =折叠/>
< /MultiDataTrigger.Setters>
< / MultiDataTrigger>
< /Style.Triggers>
< /样式和GT;
< /GroupBox.Style>
< /分组框中>
<复选框X：NAME =chk_aCONTENT =可见Grid.Column =0Grid.Row =1/>
<复选框X：NAME =chk_bCONTENT =B可见Grid.Column =1Grid.Row =1/>
< / StackPanel的>
I have an issue trying to get a GroupBox to collapse. I want a GroupBox which will collapse if all it's children are collapsed.
I have managed to achieve this using a multibinding to the properties, as shown below.
<StackPanel>
<GroupBox>
<GroupBox.Visibility>
<MultiBinding
Converter="{StaticResource multiBoolOrToVis}"
ConverterParameter="{x:Static Visibility.Collapsed}"
>
<Binding Path="a_visible"/>
<Binding Path="b_visible"/>
</MultiBinding>
</GroupBox.Visibility>
<GroupBox.Header>
<Label Content="GroupBox"/>
</GroupBox.Header>
<StackPanel>
<Label
Content="A"
Visibility="{Binding Path=a_visible, Converter={StaticResource boolToVis}}"
/>
<Label
Content="B"
Visibility="{Binding Path=b_visible, Converter={StaticResource boolToVis}}"
/>
</StackPanel>
</GroupBox>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<CheckBox
Content="A Visible"
Grid.Column="0"
Grid.Row="1"
IsChecked="{Binding Path=a_visible, Mode=TwoWay}"
/>
<CheckBox
Content="B Visible"
Grid.Column="1"
Grid.Row="1"
IsChecked="{Binding Path=b_visible, Mode=TwoWay}"
/>
</Grid>
</StackPanel>
The problem with this is we want to be able to do this multiple times and not worry about leaving off a binding. So my question is there any way of doing this generically, preferably in a style. Another requirement is that it has to be in xaml not code behind.
So my ideal answer would be a style so I could the following in my xaml.
<StackPanel>
<GroupBox Style="ChildrenVisibilityStyle">
<GroupBox.Header>
<Label Content="GroupBox"/>
</GroupBox.Header>
<StackPanel>
<Label
Content="A"
Visibility="{Binding Path=a_visible, Converter={StaticResource boolToVis}}"
/>
<Label
Content="B"
Visibility="{Binding Path=b_visible, Converter={StaticResource boolToVis}}"
/>
</StackPanel>
</GroupBox>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<CheckBox
Content="A Visible"
Grid.Column="0"
Grid.Row="1"
IsChecked="{Binding Path=a_visible, Mode=TwoWay}"
/>
<CheckBox
Content="B Visible"
Grid.Column="1"
Grid.Row="1"
IsChecked="{Binding Path=b_visible, Mode=TwoWay}"
/>
</Grid>
</StackPanel>
I have looked at these questions and they lead me to think that this isn't possible; binding in controltemplate, stackpanel visibility, border visibility.
Sorry if this has been answered before. Thanks in advance for any answers/comments.
You could use a MultiDataTrigger to collapse the GroupBox when the Children are collapsed
Here is a working example:
<StackPanel>
<GroupBox>
<GroupBox.Header>
<Label Content="GroupBox"/>
</GroupBox.Header>
<StackPanel>
<Label x:Name="lbl_a" Content="A" Visibility="{Binding IsChecked, ElementName=chk_a, Converter={StaticResource boolToVis}}" />
<Label x:Name="lbl_b" Content="B" Visibility="{Binding IsChecked, ElementName=chk_b, Converter={StaticResource boolToVis}}" />
</StackPanel>
<GroupBox.Style>
<Style TargetType="GroupBox">
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding Visibility, ElementName=lbl_a}" Value="Collapsed" />
<Condition Binding="{Binding Visibility, ElementName=lbl_b}" Value="Collapsed" />
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="GroupBox.Visibility" Value="Collapsed" />
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</Style.Triggers>
</Style>
</GroupBox.Style>
</GroupBox>
<CheckBox x:Name="chk_a" Content="A Visible" Grid.Column="0" Grid.Row="1" />
<CheckBox x:Name="chk_b" Content="B Visible" Grid.Column="1" Grid.Row="1" />
</StackPanel>
