DataTemplate 以及Template Selector 学习笔记

1. 内容控件通过ContentTemplate,列表控件通过itemTemplate 来支持模板绑定。例子如下：

模板定义：

xaml:

<DataTemplate x:Key="RadioSelector">
            <Grid  Width="500">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="2*"/>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                <TextBlock Text="{Binding ParamName}"  />
                <RadioButton Grid.Column="1" IsChecked="{Binding ParamValue, Mode=TwoWay}" Content="True" />
                <RadioButton Grid.Column="2"  Content="False" HorizontalAlignment="Right" IsChecked="{Binding ParamValue, Mode=TwoWay, Converter={StaticResource StatusConvert}}"/>
            </Grid>
        </DataTemplate>

class:

public class StatusValueConverter : IValueConverter
  {
      public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
      {
          bool status = (bool)value;
          return !status;
      }
      public object ConvertBack(object value, Type targetType, object parameter,CultureInfo culture)
      {
          bool status = (bool)value;
          return !status;
      }
  }
