如何禁用“工具提示”在文本框？ [英] How to disable "tooltip" on textbox ?

问题描述

我想在鼠标悬停时禁用文本框的工具提示，请帮助

这是我的文本框控件模板



我是什么尝试过：

< ControlTemplate x：Key =TextboxWithWatermarkTargetType ={x：Type TextBox}> ; 
< Border x：Name =borderBorderBrush ={TemplateBinding BorderBrush}BorderThickness ={TemplateBinding BorderThickness}SnapsToDevicePixels =TrueBackground ={TemplateBinding Background}> 
< Grid> 
< ScrollViewer x：Name =PART_ContentHostFocusable =FalseHorizo​​ntalScrollBarVisibility =隐藏VerticalScrollBarVisibility =隐藏/> 
< TextBlock Cursor =IBeamVerticalAlignment =Topx：Name =HintPresenterFontFamily ={TemplateBinding FontFamily}FontSize ={TemplateBinding FontSize}FontWeight ={TemplateBinding FontWeight}Margin = 5,0,5,0Horizo​​ntalAlignment =LeftForeground ={TemplateBinding Foreground}FontStyle =ItalicOpacity =0Text ={TemplateBinding ToolTip}/> 
< / Grid> 
< / Border> 
< ControlTemplate.Triggers> 
< Trigger Property =IsEnabledValue =False> 
< Setter Property =OpacityTargetName =borderValue =0.56/> 
< / Trigger> 
< Trigger Property =TextValue => 
< Setter Property =OpacityTargetName =HintPresenterValue =0.5/> 
< / Trigger> 
< /ControlTemplate.Triggers> 
< / ControlTemplate> 

解决方案

共享代码中没有设置工具提示。如果你看到一个，那么它被设置在其他地方 - 在问题中不共享的代码。检查页面或视图或代码隐藏中的实际代码。



更新

为什么不只是使用 ToolTipService 和 IsEnabled 属性。示例：

< TextBox Text =  启用测试宽度=   100 
 ToolTipService.IsEnabled =   {Binding ElementName = EnabledState，Path = IsChecked} 
 ToolTipService.ToolTip =  这是文本框的工具提示 /> 
< CheckBox x：Name =   EnabledState Content =  显示工具提示 IsChecked =   True Margin =   10 0 /> 

I want to disable textbox's ToolTip on Mouse Over, Please help
Here is my Textbox Control Template

What I have tried:

<ControlTemplate x:Key="TextboxWithWatermark" TargetType="{x:Type TextBox}">
        <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" SnapsToDevicePixels="True" Background="{TemplateBinding Background}">
            <Grid>
                <ScrollViewer x:Name="PART_ContentHost" Focusable="False" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
                <TextBlock Cursor="IBeam" VerticalAlignment="Top" x:Name="HintPresenter" FontFamily="{TemplateBinding FontFamily}" FontSize="{TemplateBinding FontSize}" FontWeight="{TemplateBinding FontWeight}" Margin="5,0,5,0" HorizontalAlignment="Left" Foreground="{TemplateBinding Foreground}" FontStyle="Italic" Opacity="0" Text="{TemplateBinding ToolTip}"/>
            </Grid>
        </Border>
        <ControlTemplate.Triggers>
            <Trigger Property="IsEnabled" Value="False">
                <Setter Property="Opacity" TargetName="border" Value="0.56"/>
            </Trigger>
            <Trigger Property="Text" Value="" >
                <Setter Property="Opacity" TargetName="HintPresenter" Value="0.5"/>
            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>

解决方案

There is no tooltip set in the code shared. If you are seeing one, then it is set somewhere else - code that is not shared in the question. Check against the actual code in the Page or View or in the code-behind.

Update
Why not simply work with the ToolTipService and the IsEnabled property. Example:

<TextBox Text="Is Enable Test" Width="100"
         ToolTipService.IsEnabled ="{Binding ElementName=EnabledState, Path=IsChecked}"
         ToolTipService.ToolTip="This is a tooltip for the textbox"/>
<CheckBox x:Name="EnabledState" Content="Show Tooltip" IsChecked="True" Margin="10 0" />
