Question

我有一个datagrid，我在其中显示有关句点开头和结尾的值。为此，我创建了一个包含2个文本块的列模板，但在最后一行中，我将这些值之间的差异显示为百分比。我想要做的是将最后一行中的第一个文本块居中，因为我在该行中只有一个值。

<DataGridTemplateColumn>
    <DataGridTemplateColumn.Header>
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="10"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}, Path=DataContext.Officer11Nome}"
                       HorizontalAlignment="Center" 
                       Grid.Column="0"
                       Grid.Row="0"
                       Grid.ColumnSpan="3"
                       />
            <TextBlock Text="Abertura" 
                       HorizontalAlignment="Center" 
                       Grid.Column="0"
                       Grid.Row="1"
                       />

            <TextBlock Text="Fechamento" 
                       HorizontalAlignment="Center" 
                       Grid.Column="2"
                       Grid.Row="1"
                       />
        </Grid>
    </DataGridTemplateColumn.Header>

    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="10"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                <TextBlock Text="{Binding Officer1Abertura}" Margin="2,0,2,0" TextAlignment="Left" Grid.Column="0"/>
                <TextBlock Text="{Binding Officer1Fechamento}" Margin="2,0,2,0" TextAlignment="Right" Grid.Column="2"/>
            </Grid>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

感谢。

这是使用触发器的解决方法（1）创建第三个属性。当显示时，其他两个将不会显示。保持为空，直到它没有计算。暂时我把它命名为differencofvalues。提供适当的名称并绑定

<DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal">
                    <TextBlock Name="textbox1" Text="{Binding Officer1Abertura}" Margin="2,0,0,0" TextAlignment="Center" Width="Auto" />
                    <TextBlock Text="{Binding differenceOfValues}" Margin="0,0,0,0" TextAlignment="Center" Width="Auto">
                        <TextBlock.Style>
                            <Style TargetType="{x:Type TextBlock}">
                                <Setter Property="Visibility" Value="Visible"/>
                                <Style.Triggers>
                                    <DataTrigger Binding="{Binding differenceOfValues}" Value="{x:Null}">
                                        <Setter Property="Visibility" Value="Collapsed"></Setter>
                                        <Setter Property="{Binding ElementName=textbox1, Path=Visibility}" Value="Visible"></Setter>
                                        <Setter Property="{Binding ElementName=textbox2, Path=Visibility}" Value="Visible"></Setter>
                                    </DataTrigger>
                                    <Trigger Property="Visibility" Value="Visible">
                                        <Setter Property="{Binding ElementName=textbox1, Path=Visibility}" Value="Collapsed"></Setter>
                                        <Setter Property="{Binding ElementName=textbox2, Path=Visibility}" Value="Collapsed"></Setter>
                                    </Trigger>
                                </Style.Triggers>
                            </Style>
                        </TextBlock.Style>
                    </TextBlock>
                    <TextBlock Name="textbox2" Text="{Binding Officer1Fechamento}" Margin="10,0,2,0" TextAlignment="Center" Width="Auto" Visibility="Collapsed" />
                </StackPanel>
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>

我使用我需要的配置创建了另一个属性。由于我在其他属性中没有值，因此非常适合。

<TextBlock Text="{Binding Officer1Percentagem}" TextAlignment="Center" Grid.Column="0" Grid.ColumnSpan="3"/>
<TextBlock Text="{Binding Officer1Abertura}" TextAlignment="Right" Grid.Column="0"/>
<TextBlock Text="{Binding Officer1Fechamento}" TextAlignment="Right" Grid.Column="2"/>
