目前我需要在数据单元格列类型DataGridTextColumn中格式化工具提示字符串
这是我的尝试： @H_301_3@<DataGrid.Columns> <DataGridTextColumn Header ="Count Number"> <DataGridTextColumn.CellStyle> <Style TargetType="DataGridCell"> <Setter Property="ToolTip" Value="{Binding CountNumber,StringFormat={}{0:00}}"> </Setter> </Style> </DataGridTextColumn.CellStyle> <DataGridTextColumn.Binding> <Binding Path="CountNumber" StringFormat="{}{0:00}" UpdateSourceTrigger="PropertyChanged" /> </DataGridTextColumn.Binding> </DataGridTextColumn> <!-- other columns--> </DataGrid.Columns>
这是我的尝试： @H_301_3@<DataGrid.Columns> <DataGridTextColumn Header ="Count Number"> <DataGridTextColumn.CellStyle> <Style TargetType="DataGridCell"> <Setter Property="ToolTip" Value="{Binding CountNumber,StringFormat={}{0:00}}"> </Setter> </Style> </DataGridTextColumn.CellStyle> <DataGridTextColumn.Binding> <Binding Path="CountNumber" StringFormat="{}{0:00}" UpdateSourceTrigger="PropertyChanged" /> </DataGridTextColumn.Binding> </DataGridTextColumn> <!-- other columns--> </DataGrid.Columns>
我也尝试过：
@H_301_3@<DataGridTextColumn.CellStyle> <Style TargetType="DataGridCell"> <Setter Property="ToolTip" Value="{Binding CountNumber}"/> <Setter Property="ToolTip.ContentStringFormat" Value="{}{0:00}"/> </Style> </DataGridTextColumn.CellStyle>但他们都不行.例如,数字3应显示为03.有什么想法吗？
解决方法
试试这个：
@H_301_3@<DataGridTemplateColumn Width="260" Header="MySample">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Age}">
<TextBlock.ToolTip>
<ToolTip>
<TextBlock Text="{Binding Path=Age,StringFormat=0\{0\}}" />
</ToolTip>
</TextBlock.ToolTip>
</TextBlock>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
Here是对这个技巧的描述.引用：
A ToolTip is a content control,which means it doesn’t really have a display model. Since the TextBox is designed to display text,the StringFormat binding property works as advertised. Button is another example of this. (Both derive from ContentControl).
想法是在ToolTip中获得StringFormat,你需要使用TextBlock设置ContentControl：
@H_301_3@<TextBlock.ToolTip> <ToolTip> <TextBlock Text="{Binding Path=Age,StringFormat=0\{0\}}" /> </ToolTip> </TextBlock.ToolTip>最重要的是在ToolTip中设置强制ContentControl,不一定,如我的示例中所示(使用DataGridTemplateColumn).
