我的DataGridCell样式中的ToolTip存在问题。当我尝试在工具提示中显示单元格的内容时,此内容会消失。我必须在每个单元格上显示此工具提示,并且我会以dinamically方式生成列,因此我无法绑定到任何属性名称。这是我的片段:
<Style x:Key="dgCellStyle" TargetType="{x:Type Controls:DataGridCell}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Controls:DataGridCell}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<Grid Background="{TemplateBinding Background}">
<ToolTipService.ToolTip>
<ContentControl Content="{TemplateBinding Content}" />
</ToolTipService.ToolTip>
<ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="Center" Margin="0,2"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
<Setter Property="BorderBrush" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsKeyboardFocusWithin" Value="True">
<Setter Property="BorderBrush" Value="{DynamicResource {ComponentResourceKey ResourceId=FocusBorderBrushKey, TypeInTargetAssembly={x:Type Controls:DataGrid}}}"/>
</Trigger>
</Style.Triggers>
</Style>
有没有人有任何想法? 感谢

如果您要将工具提示添加到DataGridTextColumn
,
您可以使用DataGridTextColumn.CellStyle property
,
请参阅以下代码段:
<DataGridTextColumn Header="ScreenName" Binding="{Binding Name}" >
<DataGridTextColumn.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="ToolTip" Value="{Binding Age}" />
</Style>
</DataGridTextColumn.CellStyle>
</DataGridTextColumn>

更新: -
如果您动态生成列,则可以在网格上处理MouseMove
事件。
然后,您可以将鼠标的坐标转换为行句柄,并相应地更改网格的工具提示。
Something like
:
private void dataGrid_MouseMove(object sender, MouseEventArgs e) {
var point = dataGrid.PointToClient(e.X, e.Y);
var hittest = dataGrid.HitTest(point.X, point.Y);
toolTip1.SetToolTip(dataGrid, hittest.Row); // **add Tooltip control to the Application!!!**
}
