Infragistics的XamDataGrid AllowEdit属性绑定不工作

Question

在我的XAML我想AllowEdit我XamDataGrid的绑定属性

<igDP:XamDataGrid.FieldSettings> 
    <igDP:FieldSettings AllowEdit="{Binding Path=DataItem.Approved}"/> 
</igDP:XamDataGrid.FieldSettings> 

但它不工作。所有其他绑定工作正常。有任何想法吗？我是新来的WPF所以任何帮助，将不胜感激

Answer 1

也许你有约束力ObservableCollection？如果是这种情况，则无法编辑您的项目。您可以尝试绑定到BindingList。

Answer 2

显然，你（仍然.....）不能将此属性绑定：http://www.infragistics.com/community/forums/t/10907.aspx 叹息......

Answer 3

我使用样式来绕过这个限制，如：

<igWPF:Field Name="SomeValue"> 
    <igWPF:Field.Settings> 
    <igWPF:FieldSettings EditorType="{x:Type igWPF:XamNumericEditor}"> 
     <igWPF:FieldSettings.EditorStyle> 
     <Style TargetType="{x:Type igWPF:XamNumericEditor}"> 
      <Setter Property="IsReadOnly" Value="{Binding DataItem.IsReadOnly}" /> 
     </Style> 
     </igWPF:FieldSettings.EditorStyle> 
    </igWPF:FieldSettings> 
    </igWPF:Field.Settings> 
</igWPF:Field>

我通常在@ larsmona的回答中使用了一种风格来实现这一点。最近我学会了使用CellBindings和FieldBindings来实现这一点。
