有没有一种样式WPF DataGrid NewItem占位符的样式 [英] Is There A Way To Style A WPF DataGrid NewItem Placeholder

问题描述

我有一个定义如下的简单数据控件

I have a simple data control defined as follows

<DataGrid x:Name="ScheduleDataGrid" AutoGenerateColumns="False" CanUserAddRows="True" CanUserDeleteRows="True" Margin="5" ItemsSource="{Binding ScheduleItems}">
    <DataGrid.Columns>

        <DataGridTextColumn...></DataGridTextColumn>
        ....
        <DataGridTextColumn...></DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>

我指定了CanUserAddRows = True。如广告所示，这会在网格底部放置一个空白行，供用户添加新行。

I have specified CanUserAddRows="True". As advertised, this puts a blank row at the bottom of the grid for the user to add a new row.

有没有一种方法可以独立于新项目占位符的样式

Is there a way to style that new item placeholder independently of the rest of the grid?

推荐答案

是的，可以更改该占位符行。

Yes it is possible to change that placeholder row.

看看我刚才做的这个例子。

Take a look at this example I just made.

<Window.Resources>
    <Style TargetType="{x:Type DataGridRow}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding}" Value="{x:Static CollectionView.NewItemPlaceholder}">
                <Setter Property="Background" Value="Yellow"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</Window.Resources>
<Grid>
    <DataGrid AutoGenerateColumns="False" CanUserAddRows="True" ItemsSource="{Binding List}">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Test" Binding="{Binding Path=Name, Mode=TwoWay}"/>
        </DataGrid.Columns>
    </DataGrid>
</Grid>

该占位符行将显示为黄色背景。

That placeholder row will appear with yellow background.
