Posted 2020-07-10 Now,DayBreak

　　前台Xaml如下：

<Grid.Resources>
    <xx:AccountStatusToVisibility x:Key="AccountStatusToVisibility" />
</Grid.Resources>
 <telerik:RadButton Visibility="{Binding Status, Mode=OneWay, Converter={StaticResource AccountStatusToVisibility}, ConverterParameter=Disabled}" 
　　Margin="0 0 5 0" Click="RadButton_Click" 
　　Command="{Binding Path=DataContext.CmdDisabled, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}" >设置启用</telerik:RadButton>

 　　后台，模板切换类：

　　　public class AccountStatusToVisibility : IValueConverter
     {
             #region "IValueConverter Members"

             public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
             {
                 if (value == null)
                 {
                     return false;
                 }

                 if (parameter != null)
                 {
                     switch (parameter.ToString())
                     {
                         case "Enabled":
                             return ((int)value == 0) ? Visibility.Collapsed : Visibility.Visible;
                         case "Disabled":
                             return ((int)value == 1) ? Visibility.Collapsed : Visibility.Visible;
                         //case "Invaild":
                         //    return ((int)value == 2) ? Visibility.Collapsed : Visibility.Visible;
                     }
                 }

                 return false;
             }

             public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
             {
                 throw new NotImplementedException();
             }

             #endregion
     }
