推荐答案

你好，萨拉斯，

.能否请您进一步介绍影响细胞颜色的条件? br/>

基本上，我们可以将CellTemplate中的属性绑定到数据源(例如Background属性显示背景色)

Hello Sarath,

  Could you please tell more about the conditions which affect the cell color?


  Basically we can bind properties in the CellTemplate to data source (For example the Background property shows the back color)

  <DataTemplate x:Key="DateTemplate" >
            
                <Border Background="{Binding CellColorData}" BorderBrush="Black" BorderThickness="1">
                    <TextBlock Text="{Binding PublishDate}" FontSize="9" HorizontalAlignment="Center" />
                </Border>
      
  </DataTemplate>

在这里，我们将Background绑定到数据源的CellColorData属性.

完成示例:

 Here we bind the Background to the CellColorData property of the Data Source.

  Complete sample:

        <DataTemplate x:Key="DateTemplate" >
            
                <Border Background="{Binding CellColorData}" BorderBrush="Black" BorderThickness="1">
                    <TextBlock Text="{Binding PublishDate}" FontSize="9" HorizontalAlignment="Center" />
                </Border>
      
        </DataTemplate>
