在ToolTip上添加DataGridTextColumn

Question

我有一个DataGrid，它的DataGridTextColumn是这样的：

<DataGrid x:Name="DonneesBrutes" IsReadOnly="True" ItemsSource="{Binding Path=ResultatCollectionGrande}" Margin="10,65,0,0" AutoGenerateColumns="False" EnableRowVirtualization="True" RowDetailsVisibilityMode="VisibleWhenSelected">
    <DataGrid.Columns>
        <DataGridTextColumn x:Name="PrisEnCompte" Binding="{Binding Path=Flag}" Header="Pris En Compte"></DataGridTextColumn>
        <DataGridTextColumn x:Name="PMRQ" Width="*" Binding="{Binding Path=Pmid}" Header="PMID"></DataGridTextColumn>
        <DataGridTextColumn x:Name="Ligne" Width="40" Binding="{Binding Path=Ligne}" Header="Ligne" IsReadOnly="True"></DataGridTextColumn>
        <DataGridTextColumn x:Name="LibellePMRQ" Width="*" Binding="{Binding Path=LibellePmrq}" Header="Libellé PMRQ">
            <DataGridTextColumn.HeaderStyle>
                <Style TargetType="DataGridColumnHeader">
                    <Setter Property="ToolTip"
        Value="{Binding RelativeSource={RelativeSource Self},
                        Path=Column.(ToolTipService.ToolTip)}"/>
                </Style>
            </DataGridTextColumn.HeaderStyle>
        </DataGridTextColumn>
        <DataGridTextColumn x:Name="OTM" Width="*" Binding="{Binding Path=Otm}" Header="OTM"></DataGridTextColumn>
        <DataGridTextColumn x:Name="TOTM" Width="50" Binding="{Binding Path=Totm}" Header="TOTM"></DataGridTextColumn>
        <DataGridTextColumn x:Name="LibelleTOTM" Width="*" Binding="{Binding Path=LibelleTotm}" Header="Libellé TOTM">
            <DataGridTextColumn.HeaderStyle>
                <Style TargetType="DataGridColumnHeader">
                    <Setter Property="ToolTip"
        Value="{Binding RelativeSource={RelativeSource Self},
                        Path=Column.(ToolTipService.ToolTip)}"/>
                </Style>
            </DataGridTextColumn.HeaderStyle>
        </DataGridTextColumn>
        <DataGridTextColumn x:Name="GA" Width="70" Binding="{Binding Path=GroupeAlerte}" Header="GA"></DataGridTextColumn>
        <DataGridTextColumn x:Name="Discipline" Width="120" Binding="{Binding Path=Discipline}" Header="Discipline"></DataGridTextColumn>
        <DataGridTextColumn x:Name="DisciplineSubstituee" Width="120" Binding="{Binding Path=DisciplineSubstituee}" Header="Discipline Substituée"></DataGridTextColumn>
        <DataGridTextColumn x:Name="Remarque" Width="*" Binding="{Binding Path=.Remarque}" Header="Remarque"></DataGridTextColumn>

    </DataGrid.Columns>
</DataGrid>

当鼠标在我的DataGridTextColumn LibelleTOTM上时，我想创建一个弹出窗口。为了做到这一点，我做了：

<DataGridTextColumn x:Name="LibelleTOTM" Width="*" Binding="{Binding Path=LibelleTotm}" Header="Libellé TOTM">
    <DataGridTextColumn.HeaderStyle>
        <Style TargetType="DataGridColumnHeader">
            <Setter Property="ToolTip"
                    Value="{Binding RelativeSource={RelativeSource Self},Path=Column.(ToolTipService.ToolTip)}"/>
        </Style>
    </DataGridTextColumn.HeaderStyle>
</DataGridTextColumn>

我已经在网上找到了这个解决方案，但是它对我的解决方案不起作用。我已经适应了我的情况，但可能还不够.当鼠标越过LibelleTOTM时，什么都不会发生。TargetType是错的，我就不能把自己绑成这样吗？我想打开一个带有DataGridTextColumn值的弹出窗口，所以在ToolTip中发送我们在<DataGridTextColumn x:Name="LibelleTOTM" Width="*" Binding="{Binding Path=LibelleTotm}" Header="Libellé TOTM">上找到的Binding="{Binding Path=LibelleTotm}"

如果有人知道那里遗漏了什么，有什么不对，我该怎么做才能做到这一点？

提前谢谢。

HeaderStyle应用于列标题。除非我在你的问题中遗漏了什么，否则你需要瞄准DataGridCell本身，就像这样。

<DataGridTextColumn.CellStyle>
    <Style TargetType="DataGridCell" BasedOn="{StaticResource {x:Type DataGridCell}}">
          <Setter Property="ToolTip" Value="{Binding Del_Date, StringFormat=MM/dd/yyyy HH:mm}" />
    </Style>
</DataGridTextColumn.CellStyle>
