wpf为datagrid每个单元格设置tooltip

Question

比如单元格数据为1，当鼠标移到这个单元格时，能显示出“壹”，其中"1"对应"壹"放在了字典资源中。
这样的怎么实现呢？

用DataGrid的CellStyle和DataTrigger

<DataGrid ItemsSource="{Binding YourData}" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Column 1" Binding="{Binding Property1}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="ToolTip">
                        <Setter.Value>
                            <MultiBinding StringFormat="{}Property 1: {0}">
                                <Binding Path="Property1" />
                            </MultiBinding>
                        </Setter.Value>
                    </Setter>
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>

        <DataGridTextColumn Header="Column 2" Binding="{Binding Property2}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="ToolTip">
                        <Setter.Value>
                            <MultiBinding StringFormat="{}Property 2: {0}">
                                <Binding Path="Property2" />
                            </MultiBinding>
                        </Setter.Value>
                    </Setter>
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>

        <!-- Add more columns with different ToolTip bindings as needed -->
    </DataGrid.Columns>
</DataGrid>
