如何仅使tabitem的标题响应鼠标事件 [英] How to make only the header of the tabitem respond to the mouse event

问题描述

到目前为止，我有我的xaml ...

 < TabControl> 
< TabItem Header =tab 1> 
任何文本
< / TabItem> 
< TabItem Header =tab 2> 
< TextBox> blah< / TextBox> 
< / TabItem> 
< TabControl.Resources> 
< Style TargetType =TabItem> 
< EventSetter Event =MouseDoubleClickHandler =TabItemMouseDoubleClick/> 
< / style> 
 < / TabControl> 
  

...和我的事件处理程序...

  void TabItemMouseDoubleClick（object sender，MouseButtonEventArgs e）
 {} 
  

现在，当双击标签项目标题事件触发时，当点击标签项目内容区域时它不会触发（这是我想要的），但是当我在TabItem中放置一个文本框时，双击文本框会触发事件。我试图只获取TabItem的头部来触发事件 - 任何想法？解析方案

对于其他人来说，最后xaml获取tabItems头只发送事件是...

 < TabControl> 
< TabItem Header =tab 1> 
任何文本
< / TabItem> 
< TabItem Header =tab 2> 
< TextBox> blah< / TextBox> 
< / TabItem> 
< TabControl.Resources> 
< Style TargetType =TabItem> 
 
< Setter Property =HeaderTemplate> 
< Setter.Value> 
< DataTemplate> 
<标签内容={绑定}> 
< Label.Style> 
< Style TargetType =标签> 
< EventSetter Event =MouseDoubleClickHandler =TabItemMouseDoubleClick/> 
< / style> 
 < / Label> 
< / DataTemplate> 
 < / Setter> 
< / style> 
 < / TabControl> 
  

I'm trying to make only the header of the TabItem send an event.

So far I have my xaml...

<TabControl>
    <TabItem Header="tab 1">
             Any text
    </TabItem>
    <TabItem Header="tab 2">
        <TextBox>blah</TextBox>
    </TabItem>
    <TabControl.Resources>
        <Style TargetType="TabItem">
            <EventSetter Event="MouseDoubleClick" Handler="TabItemMouseDoubleClick"/>
        </Style>
    </TabControl.Resources>
</TabControl>

...and my event handler...

void TabItemMouseDoubleClick(object sender, MouseButtonEventArgs e)
{}

Now, when double clicking the tab item header the event fires, when clicking the tab item content area it doesn't fire (which is what I want), but when I put a text box in the TabItem, the event fires upon double clicking the textbox. I'm trying to get only the header of the TabItem to fire the event - any ideas?

解决方案

For others, the final xaml to get the tabItems header only sending the event is...

    <TabControl>
        <TabItem Header="tab 1">
                 Any text
        </TabItem>
        <TabItem Header="tab 2">
            <TextBox>blah</TextBox>
        </TabItem>
        <TabControl.Resources>
            <Style TargetType="TabItem">

                <Setter Property="HeaderTemplate">
                    <Setter.Value>
                        <DataTemplate>
                            <Label Content="{Binding}">
                                <Label.Style>
                                    <Style TargetType="Label">
                                        <EventSetter Event="MouseDoubleClick" Handler="TabItemMouseDoubleClick"/>
                                    </Style>
                                </Label.Style>
                            </Label>
                        </DataTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </TabControl.Resources>
    </TabControl>
