选中时更改网格行的背景颜色
Change Background color of grid row when selected
我的 itemscontrol
当前正在正确加载每一行。我试图让它在用户选择它时更改每一行的背景颜色。

</Grid>
目前看起来像这样:
我尝试添加一个 DataTemplate.Triggers
,但它没有接缝做任何事情。您如何准确地检测到已选择 itemscontrol 中的一行?我发现的唯一示例使用 datagrid
。我尝试将我的更改为 datagrid
而不是 itemscontrol
,但是它不会加载数据。
数据网格:
<DataGrid x:Name="grd" Background="White" DataContext="{Binding DatabaseServers}" Grid.Row="2">
<Image Source="{Binding StatusImage}" Height="10" Width="10" />
<Label Grid.Column="1" HorizontalAlignment="Left" Content="{Binding ServerName}" />
<Label Grid.Column="2" HorizontalAlignment="Left" Content="{Binding SourceDatabase}" />
<TextBox x:Name="dst" Grid.Column="3" Text="{Binding DestinationDatabase , Mode=TwoWay, UpdateSourceTrigger=LostFocus}" VerticalAlignment="Top" />
<Label Grid.Column="4" Content="{Binding Status}" VerticalAlignment="Top" />
<Button Grid.Column="4" BorderThickness="0" HorizontalAlignment="Center" Width="50" Margin="3" Content="{Binding Status}" Command="{Binding EnabledCommand}" CommandParameter="{Binding}" />
</DataGrid>
只是显示一堆行,每一行都没有数据。
我是 WPF 的新手,所以我真的不知道我做错了什么。
这是你想要的 DataGrid
我正在使用 MVVM
Window.xaml
