Wpf DataGrid Add new row
提问by Mandar Jogalekar
I have managed to get DataGridto show new row for adding new item.
Problem i face now is i want data in the rest of wpf DataGridto be read only and only new row should be editable.
我设法DataGrid显示新行以添加新项目。我现在面临的问题是我希望 wpf 其余部分的数据DataGrid是只读的，并且只有新行应该是可编辑的。
Currently this is how my DataGridlooks.
目前这就是我的DataGrid样子。
<DataGrid AutoGenerateColumns="False" Name="DataGridTest" CanUserAddRows="True" Grid.Row="2" ItemsSource="{Binding TestBinding}" >
<DataGrid.Columns>
<DataGridTextColumn Header="Line" IsReadOnly="True" Binding="{Binding Path=Test1}" Width="50"></DataGridTextColumn>
<DataGridTextColumn Header="Account" IsReadOnly="True" Binding="{Binding Path=Test2}" Width="130"></DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
But since I have kept the columns read only, a new row also adds as read only which is what I don't want.
但是由于我将列保持为只读，因此新行也添加为只读，这是我不想要的。

<DataGridTextColumn Header="Account" IsReadOnly="True" Binding="{Binding Path=Test2}" Width="130"></DataGridTextColumn>

</DataGrid>
<Button Content="Add new row" HorizontalAlignment="Left" Margin="0,10,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click_1"/>

Just simply use this Styleof DataGridRow:
只需简单地使用这个Style的DataGridRow：
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource Self},Path=IsNewItem,Mode=OneWay}" />
</Style>
</DataGrid.RowStyle>
