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:
这是我的尝试:
<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:
<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:
<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:
<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).
