我需要一些可编辑的 DataGrid 行,而另一些则不需要。
<DataGrid ItemsSource="{Binding Items.View}" AutoGenerateColumns="False" CanUserAddRows="False" >
<DataGrid.Columns>
<DataGridTextColumn IsReadOnly="True" Binding="{Binding Timestamp}" Width="Auto" >
<DataGridTextColumn.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{lex:Loc DateTime}" />
</DataTemplate>
</DataGridTextColumn.HeaderTemplate>
</DataGridTextColumn>
<DataGridTextColumn Binding="{Binding Value}" Width="Auto" >
<DataGridTextColumn.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{lex:Loc Value}" />
</DataTemplate>
</DataGridTextColumn.HeaderTemplate>
</DataGridTextColumn>
我的项目中有一个属性 IsEditable。我喜欢这样的东西:
<DataGridTextColumn IsReadOnly="{Binding IsEditable, Converter={StaticResource InverseBooleanConverter}}" Binding="{Binding Value}" Width="Auto" >
与此同时,我知道这不可能那么容易。虽然我找不到适合我的问题的解决方案。
更新
不是那么重要,但为了更好地理解,我将从视图模型中添加更多数据。
private ObservableCollection<MeasuredValue> _last60values;
public ObservableCollection<MeasuredValue> Last60Values
{
get { return _last60values; }
set { _last60values = value; }
}
Items = new CollectionViewSource();
Items.Source = Last60Values;
和我的“测量值”
namespace PQS.Model
{
public class MeasuredValue : CloneableBaseEntity<MeasuredValue>
{
public DateTime Timestamp { get; set; }
.
.
.
private double _value;
[Range(0.0, double.MaxValue)]
public double Value
{
get { return _value; }
set
{
_value = value;
RaisePropertyChanged("Value");
}
}
private bool _isEditable;
public bool IsEditable
{
get { return _isEditable; }
set
{
_isEditable = value;
RaisePropertyChanged(() => IsEditable);
}
}
}
}
