我搜索并发现我无法直接在setter.value中设置工具提示(在style.xaml文件中)。但是,我可以使用静态资源来设置工具提示。
我的问题是,因为我需要为工具提示提供动态文本,所以我不能使用静态资源。我该怎么做?
这是我的例子。
<Style x:Key="ErrorStyleRadius" TargetType="{x:Type FrameworkElement}">
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding (Validation.HasError), RelativeSource={RelativeSource Mode=Self}}" Value="True"/>
<Condition Binding="{Binding (Validation.Errors), RelativeSource={RelativeSource Mode=Self}, Converter={StaticResource IsError}}" Value="True"/>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="ToolTip">
<Setter.Value>
<ToolTip>
<Label Content="{Binding somePropertyHere}"/>
</ToolTip>
</Setter.Value>
</Setter>
<Setter Property="Validation.ErrorTemplate" Value="{StaticResource ErrorControlTemplateRadiusError}"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding (Validation.HasError), RelativeSource={RelativeSource Mode=Self}}" Value="True"/>
<Condition Binding="{Binding (Validation.Errors), RelativeSource={RelativeSource Mode=Self}, Converter={StaticResource IsWarning}}" Value="True"/>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors), Converter={StaticResource ValMsg}}"/>
<Setter Property="Validation.ErrorTemplate" Value="{StaticResource ErrorControlTemplateRadiusWarning}"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</Style.Triggers>
</Style>
用法,我可以用作
<textbox style={staticresource ErrorStyleRadius} text={bind name, validationOnDataError=true}/>

你为什么不试试这个 -
<ToolTip x:Key="MyToolTip"
DataContext={Binding PlacementTarget, RelativeSource={RelativeSource Self}}>
<Label Content="{Binding Text}"/>
</ToolTip>
<Style x:Key="ErrorStyleRadius" TargetType="{x:Type FrameworkElement}">
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding (Validation.HasError), RelativeSource={RelativeSource Mode=Self}}" Value="True"/>
<Condition Binding="{Binding (Validation.Errors), RelativeSource={RelativeSource Mode=Self}, Converter={StaticResource IsError}}" Value="True"/>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="ToolTip" Value={StaticResource MyToolTip}>
</Setter>
<Setter Property="Validation.ErrorTemplate" Value="{StaticResource ErrorControlTemplateRadiusError}"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</Style.Triggers>
</Style>
您可以在StaticResource中提供属性名称。它将动态更新工具提示。

如果要将文本设置为Validation.Error,也可以从样式中设置工具提示 -
<Trigger Property="Validation.HasError" Value="True">
<Setter Property="ToolTip"
Value="{Binding RelativeSource={RelativeSource Self},
Path=(Validation.Errors)[0].ErrorContent}" />
</Trigger>
