WPF DataGridCell Margin
提问by BrianKE
I have the following data grid:
我有以下数据网格：
<DataGrid Name="PropertiesDataGrid"
ItemsSource="{Binding PropertiesDataView, UpdateSourceTrigger=PropertyChanged}"
SelectedItem="{Binding SelectedProperty, Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}"
AutoGenerateColumns="False"
CanUserAddRows="False"
MaxHeight="200">
<i:Interaction.Behaviors>
<helper:ScrollIntoViewBehavior/>
</i:Interaction.Behaviors>
<DataGrid.Columns>
<DataGridTemplateColumn Header="">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Command="Delete"
Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">
<Image Source="../Resources/red_x.ico"
Height="15" />
</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTextColumn Header="ID"
Width="50"
Binding="{Binding ID}"
ElementStyle="{StaticResource CenterTextCellStyle}"
IsReadOnly="True" />
<DataGridTextColumn Header="PropertyName"
Width="*"
Binding="{Binding PropertyName}"
ElementStyle="{StaticResource LeftTextCellStyle}" />
<DataGridTextColumn Header="PropertyValue"
Width="300"
Binding="{Binding PropertyValue}"
ElementStyle="{StaticResource LeftTextCellStyle}" />
</DataGrid.Columns>
</DataGrid>
Applied to this data grid is the following style:
应用于此数据网格的是以下样式：
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="Height" Value="22" />
<Setter Property="Margin" Value="5,0,0,0" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Grid Background="{TemplateBinding Background}">
<ContentPresenter VerticalAlignment="Center" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
This style adds 5 pixels of spacing to the left of the cell contents and centers the text vertically.
此样式在单元格内容的左侧添加 5 个像素的间距，并使文本垂直居中。
I would like to set the margin of just the first column's cells (<DataGridTemplateColumn Header="">) to 0. How can I set this in the DataTemplate. I know the Margin has to be set on DataGridCell (found by using Snoops) but do not know how to implement in the <DataGridTemplateColumn.CellTemplate>
我想将第一列单元格 ( <DataGridTemplateColumn Header="">)的边距设置为 0。如何在 DataTemplate 中设置它。我知道必须在 DataGridCell 上设置 Margin（通过使用 Snoops 找到）但不知道如何在<DataGridTemplateColumn.CellTemplate>

Cascade the style:
层叠样式：
<DataGridTemplateColumn Header="">
<DataGridTemplateColumn.CellStyle>
<Style TargetType="{x:Type DataGridCell}" BasedOn="{StaticResource {x:Type DataGridCell}}">
<Setter Property="Margin" Value="0" />
</Style>
</DataGridTemplateColumn.CellStyle>
