我是wpf的新手。我有一个DataGrid表格wpftoolkit,我只需要在选择行并且记录不是最后一个(新记录项目)时在模板中显示按钮
<dg:DataGrid AutoGenerateColumns="False" DockPanel.Dock="Top"
ItemsSource="{Binding Source={StaticResource Entries}}"
Name="dataGrid" >
<dg:DataGrid.Columns>
<dg:DataGridTextColumn Header="Term" Width="2*" Binding="{Binding Path=Term}"/>
<dg:DataGridTextColumn Header="Definition" Width="5*" Binding="{Binding Path=Definition}"/>
<dg:DataGridTemplateColumn Header="">
<dg:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Click="btnRemove_Click">Remove</Button>
</DataTemplate>
</dg:DataGridTemplateColumn.CellTemplate>
</dg:DataGridTemplateColumn>
</dg:DataGrid.Columns>
</dg:DataGrid>
如何将Visibility属性与datagrid绑定?
我没有完全解决方案,在未选择行时禁用按钮:
<dg:DataGridTemplateColumn >
<dg:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Content="Remove" Click="btnRemove_Click" >
<Button.Style>
<Style TargetType="{x:Type Button}" >
<Setter Property="Visibility" Value="Hidden" />
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type dg:DataGridRow}}, Path=IsSelected}" Value="True">
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</DataTemplate>
</dg:DataGridTemplateColumn.CellTemplate>
</dg:DataGridTemplateColumn>

一种解决方案是为Visibility属性编写ValueConverter,该属性被绑定到DataRow。在ValueConverter上检查它是否是一个新行,然后将Visibility设置为Hidden else Visible。
