如何在IE和Chrome中获得相同的结果(半星).

在chrome:http://jsfiddle.net/Auqj8/

.star {
    font-size: x-large;
    width: 50px;
    display: inline-block;
    color: gray;
}
.star:last-child {
    margin-right: 0;
}
.star:before {
    content: '\2605';
}
.star.on {
    color: gold;
}
.star.half:after {
        content: '\2605';
        color: gold;
        margin-left: -20px;
        width: 10px;
        position: absolute;
        overflow: hidden;
}

在IE中:http://jsfiddle.net/86pqx/

谢谢.

我希望在我的属性为空时禁用我的网格,并在非空时启用.

在我的.XAML中:

  <Grid Grid.Row="2" IsEnabled="{Binding ElementName=dgCustomers, Path=SelectedItem}">
      <my:ProductsHistoryDetailView />
  </Grid>

在我的ViewModel.cs中:

    public ProductHistory SelectedItem
    {
        get { return _SelectedItem; }
        set
        {
            if (_SelectedItem != value)
            {
                _SelectedItem = value;
                RaisePropertyChanged(() => SelectedItem);
            }
        }
    }
