选中时更改网格行的背景颜色

Question

我的itemscontrol当前正在正确加载每一行。 我试图让它改变用户选择时每行的背景颜色。

<Grid>

                                    <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}" />
                                </Grid>
                                <DataTemplate.Triggers>
                                    <DataTrigger Binding="{Binding selected }" Value="True">
                                        <Setter Property="Background" Value="Yellow" TargetName="dst" />
                                    </DataTrigger>
                                </DataTemplate.Triggers>
                            </DataTemplate>
                        </ItemsControl.ItemTemplate>
                    </ItemsControl>
                </Grid>

当前看起来像这样：

我尝试添加一个DataTemplate.Triggers但它并没有做任何事情。 您如何准确地检测到items控件中的一行已被选中？ 我发现的唯一示例使用了datagrid 。 我尝试将我的更改为datagrid而不是itemscontrol ，但是这样它不会加载数据。

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>

仅显示一堆线，每行中没有数据。

我是WPF的新手，所以我真的无法弄清楚我在做什么错。

这是您想要使用MVVM使用DataGrid im的内容

Window.xaml

<Grid Margin="10">
        <StackPanel Orientation="Vertical">
            <Label Content="DataBases" Width="150" Height="50" HorizontalAlignment="Left" FontSize="20"/>
            <DataGrid Name="DgDataSource" AutoGenerateColumns="False" CanUserAddRows="False" ItemsSource="{Binding SourceData}">
                <DataGrid.Columns>
                    <DataGridTextColumn Header="ServerName" Binding="{Binding ServerName}" Width="2*"/>
                    <DataGridTextColumn Header="SourceDatabase" Binding="{Binding SourceDatabase}" Width="2*"/>
                    <DataGridTextColumn Header="DestinationDatabase" Binding="{Binding DestinationDatabase}" Width="2*"/>
                    <DataGridTemplateColumn  Width="*" Header="Status" >
                        <DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <Button Content="{Binding Status}" Command="{Binding EnabledCommand}"></Button>
                            </DataTemplate>
                        </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>
                </DataGrid.Columns>
            </DataGrid>
        </StackPanel>

    </Grid>

查看模型

 public class WindowViewModel
    {
        public ObservableCollection<DataSource> SourceData { get; set; }

        public WindowViewModel()
        {
            Initialize();
        }
        private void Initialize()
        {
            SourceData = new ObservableCollection<DataSource>
            {
                new DataSource() {Status = "Stop", ServerName = "Test 1", SourceDatabase = "Unknown",DestinationDatabase = "blabla....."},
                new DataSource() {Status = "Work", ServerName = "Test 2", SourceDatabase = "Unknown",DestinationDatabase = "blabla....."},
                new DataSource() {Status = "Stop", ServerName = "Test 3", SourceDatabase = "Unknown",DestinationDatabase = "blabla....."}
            };
        }
    }

模型

 public class DataSource
    {
        public string Status { get; set; }

        public string ServerName { get; set; }

        public string SourceDatabase { get; set; }

        public string DestinationDatabase { get; set; }

    }
